Cost Recovery for Energy Efficiency Programs – An Ignorant Idea

Energy Efficiency1 comment

If you haven’t seen Michaels’ recent self-indulgent video, you might want to do that now.  It is many hours of video shooting reduced to a fine sauce, just under four minutes.  My interview, for example, lasted maybe 45 minutes and maybe 30 seconds of it are included in the video.  One line I’m pleased to have been captured and included was the statement that there is a limitless supply (and immense variety) of learning available in our industry.  One thing I know little about is the guts of the utility business and cost recovery for energy efficiency programs.  So why not write about that and see if I can avoid being a fool.

This post is brought to you by the report The Old Model Isn’t Working: Creating the Energy Utility for the 21st Century, by the American Council for an Energy Efficient Economy (ACEEE).

Since there are always new readers, I’ll say it for the 300th time, investor owned utilities are regulated monopolies.  As ACEEE points out, just imagine how ridiculous it would be to have duplicative competitive delivery of power to your house.  It wouldn’t work for a bunch of reasons but space is limited so I’m not going to explain any of that.

Rates are comprised of investor return on the rate base plus operating expenses.  Consider the rate base to be long-term hard assets – power plants, transmission and distribution (T&D), and the opulent headquarters buildings downtown, complete with restaurants, Starbucks, and spas.  The cost of owning this stuff is stock dividends, bond dividends/yields, and bank interest.  Operating costs obviously include fuel, and I would guess trucks.  And despite what they say, employees are an expense and not an asset [1], [2].

Take the cost of all that stuff, including profit for investor/banker, and divide by energy sales to arrive at the allowed cost of energy.  Here I go out on a limb.  Profits are very sensitive to economic activity.  Since utilities are monopolies with not-quite-guaranteed profit, their profit margins are low.  Sales growth is tiny, if anything.  Return on investment for investors is primarily the dividend yield, which is protected like Fort Knox.  The first thing I’m thinking is yields are 3-4% for major utilities in the US.  It would seem[3] very foolish to buy US bonds at a yield of 1.5% against this kind of return.

Energy efficiency programs are obviously at odds with the utility business model.  It would be like Carl’s Jr. running ads: “Feeling a little chubby today?  Get a clue: 67,000 calories in one of these babies.”  I’m not sure why they erode the appeal with that slice of tomato.

The programs cost the utility money to run (reduced earnings), erode sales (reduced earnings), and provide no ROI on the dollars spent (no earnings).  Cost recovery for energy efficiency programs gets all the hype.  I’m going to run out on a limb again at the risk of revealing my ignorance of this subject.

What does DSM stand for?  Demand side management.  (I’m firmly on the ground hugging the tree trunk still; not out on a limb yet)  By what measure are goals set for energy efficiency programs?  Energy, NOT demand.  Now I’m on the branch ready to go out on a limb.

What if we incentivized utilities for energy savings by allowing them to hike demand charges while decreasing energy prices somewhat?

To get higher return on assets for investors, one way to do it is use the stuff more.  It’s obvious.  There are lots of megawatts of generating capacity that get used a couple hours, a day, or few days a year.  Charging more for demand will increase investor ROI and incentivize customers to squish their annual peak demand lower, but get more full load hours from the rate base.

Unfair for large power users?  Not really.  It is like lowering and flattening tax rates while removing deductions.  Taxpayers would squeal that their health insurance, mortgage, property tax, kid, this that and the other expenses will no longer be written off, and they will pay more taxes.  NO!  Cut the rates so by the end of the year, the same dollars are paid.  Ditto for tariffs.  Increase demand charges, cut energy charges, and pay the same by the end of the year.

Let’s see.  Return comes from the assets.  The operating costs are a pass through.  Well, let’s heap some of the pass through cost onto return on assets for investors.  But this will not make utilities whole for their operating expenses.  Good!  Therefore, they will have an incentive to reduce their operating expenses/losses – a huge one of which is fuel, coal, natural gas, all producing CO2.  This would reward energy efficiency, pressure end users to reduce peak and run flatter, and get more operating hours and revenue from utility assets.

What is the problem here?  I don’t get it.

Demand Side Market Transformation

Energy Efficiency0 comments

Last week I was reading a couple regulatory dockets; one by a citizen and another by an intervener.  They made some good points, including a situation of being locked out of the market[1] in one’s own state, to which I replied, “Welcome to the party.”  Both dockets had a ring of “market transformation”.

Our friends at the American Council for an Energy Efficient Economy (ACEEE) define market transformation as, “The strategic process of intervening in a market to create lasting change in market behavior by removing identified barriers or exploiting opportunities to accelerate the adoption of all cost-effective energy efficiency as a matter of standard practice.”  I think I am correct in saying that behavior in this sentence includes consumers choosing CFLs over incandescent as one example, and in a broad sense, consumer choices.

Some market transformation, per my definition, has been very successful, including the CFL example mentioned previously.  ENERGY STAR® appliances, including refrigerators, have been another one, to the point that some programs are dropping refrigerators from their portfolios.  Another odd one is ground source heat pumps.  In certain spheres, ground source heat pumps have taken on a cult-like following, and to say ground source heat pumps don’t make the meter spin backwards in every application is blasphemy[2].  After beatings from “trade allies” for a heat pump study Michaels completed a few years back, I found last winter that MidAmerican Energy is dropping them from their energy efficiency plan going forward due to lack of cost effectiveness.  Touché.

Aside from equipment choice, market transformation to its advocates includes training the masses to be energy experts – contractors, controls companies, architect and engineering (design) firms, and so on.  This sort of market transformation is never going to happen.  Why?  It is easy to teach people to care for their lawn.  It isn’t easy or cheap to teach people how to successfully replace four knee joints per day.  Have you ever seen a knee surgery performed?  To an ignoramus it looks easy – like carpentry, cobbling, and seamster rolled into one.

Barrier number one, therefore, is time and money.  It reminds me of a manufacturer one time that wanted us to show them in a day or two how to be do-it-yourselfer energy efficiency experts.  That would be like satiating a couple thousand ravenous souls with two croissants and a few mackerel.  That is, give “us” the equivalent of an engineering degree and 10-20 years’ experience in a couple days.  If only it could be reproduced and stored on a micro SD chip placed under the tongue, dissolved into the bloodstream, and stored permanently in the brain.

Barrier number two:  Few capable of sawing lumber and wielding a hammer and chisel are interested in becoming an orthopedic surgeon.  Nor does the orthopedic surgeon really want to become a neurosurgeon or dermatologist.  The core building blocks of the MD profession, as they are with engineering, are similar.  Energy efficiency, particularly for large commercial and industrial systems and process optimization, requires highly trained and experienced talent.  Even converting a commissioning agent to retrocommissioning (RCx) agent is no small feat because they are substantially different services.  In the former, the professional is ensuring the systems are built and operating as intended, while the latter only cares about the design intent for purposes of understanding how it is supposed to work.  Any RCx agent worth paying is going to go far beyond the design intent to capture savings in addition to recognizing design flaws or mistakes that result in waste – and how to fix it.

Like consumer choice, markets can be transformed and are transformed on the demand side of the equation.  While buyers obviously don’t understand the details of RCx, or they would do it themselves, they love the benefits and the word spreads to propagate the service/program – transforming the market.

market transformationLastly, when it comes to market transformation, supply cannot be dictated.  The market, like every other, gravitates to the best products and services.  A layperson example of this is farming.  Many today would like the family farm of the 1950s – the ones that include 25 head of swine, a dozen dairy cows, a few beef cattle, seven egg-laying chickens, a collie, and three cats to take care of the mice.  That doesn’t work anymore.  Why?  Because the market calls for cheap food, and that’s why prices for many items have remained the same or even fallen in the past 25 years – for sure when adjusted for inflation.

A prosperous market serving these advanced programs consists of few firms that really know what they are doing.  Spreading it around isn’t cost effective, nor will it last; i.e., transform the market.  Market transformation agents want the 1950s farm with today’s cheap food.  They cannot both be had.

[1] Locked out of the market means other firms provide program funded services to end users, free or massively subsidized by the program.

[2] Ground source heat pump systems work great for many applications and have many strong attributes, but like everything else, they are not the best in all applications, particularly for residential when competing against natural gas.  Refer to the referenced report.

Energy Management System: Not Another Litter Box

Energy Efficiency0 comments

In recent weeks, I have been spending considerable time examining energy management system projects for energy efficiency program evaluation on the east coast.  My conclusion is this: blown opportunity abounds.

The program documentation for one particular project drips with evidence that the project is a free rider, which means the project would have happened anyway in absence of the program.  How do I reach this conclusion?  First, the calculation methodology could work if the user knew what they were doing, but it is clear they either don’t know what they are doing or don’t care to get it right – sell the project, throw some information at the utility in return for cash.  Second, it is a dual fuel (gas and electric savings) project. It appears the project was sold on the merits of electric savings, and the gas savings were pasted on like duct tape holding a tail light in place – again, hand waiving for cash.  Lastly, the return on investment with a simple payback period of about 10 years isn’t nearly good enough for a commercial office building.

The larger issue is the building HVAC design and the seemingly blown opportunity with this energy management system.  This reminds me of the question, “So what keeps you motivated and going all these years in energy efficiency, Jeff?”  Part of the answer is there is an infinite volume of stuff to learn in this business.  In this case, one never ceases to see weird HVAC system designs, regardless of how many hundreds of buildings have been examined.

The aforementioned facility appears to have been built in the 1980s based on its architectural features.  Stick with me through the next couple sentences.  The documentation is poor and inconclusive and leaves me guessing, but it has the fingerprints of a variable air volume system with packaged terminal air conditioners on the perimeter.  For most people who don’t know what this means – think central ducted and cooling system in a home with an electric space heater and window air conditioner in each room, to boot – but this is more like an apartment with the central heating and cooling system AND separate heating and cooling capability in each housing unit; or in this case, office.  Central systems battling it out with crappy motel-like equipment.  You know – human sacrifice, dogs and cats living together; mass hysteria.

The first blown opportunity is construction of this mess.  The design of the HVAC system in this building is the polar opposite of what we posited in last year’s American Council for an Energy Efficient Economy, aka ACEEE, Summer Study for buildings.  It is overly complex, duplicative, and primed for heating and cooling systems fighting one another.  In this case, the heating is delivered by super costly electric resistance heat, and  the central heating system (fuel source = natural gas) provides only about 20% of the heating BTU’s.  The rest is from electric toaster coils.  Meanwhile, central areas of the building probably need cooling all the time, and so, the central system provides it, likely to the perimeter areas as well.

The second blown opportunity is concurrent with the installation of the energy management system.  This customer installed an energy management system at a cost of maybe a couple dollars per square foot.  There is no mention of controlling stuff to minimize or eliminate rampant simultaneous heating and cooling, and I’ll bet my house that this is occurring excessively.  This sort of blown opportunity is unfortunately more the norm than the exception.

Articles are published far and wide talking about the energy efficiency potential in buildings, but the industry is too ignorant, and I say this with affection, to capitalize on the real opportunities.  The uninformed observer would think these sorts of energy management systems would be milking the last drops from the turnip when that is not the case at all.

Energy Management SystemOur industry needs to transform to what I call knowledge based programs for large commercial and industrial sectors.  Recruiting an army of “trade allies” (I hate that term) to do the heavy lifting, unsupervised, is not nearly enough.  Program implementers need to do far more than herd cats.

Leveraging projects with knowledge includes things like design, specification, scope of work review, and optimization of the design and control sequencing prior to implementation; followed by functional performance testing of measures once implemented.

This leveraging maximizes benefits for everyone involved.

  • Customer saves more energy; gets higher ROI
  • Happy customer = good business for cat
  • More impacts for program
  • No free riders

One of these Days

Energy Efficiency, Retrocommissioning (RCx), Tax Stuff0 comments

Our friends at the American Council for an Energy Efficient Economy (ACEEE) have published another source report worthy of a post on this blog.  The title of this report is Frontiers of Energy Efficiency: Next Generation Programs Reach for High Energy Savings, which can be found here.

The report is quite a detailed whomper, but I gravitated to the commercial and industrial sections of the Executive Summary to see what they have to say.  They are singing our (Michaels) song all the way baby, and we can hum to that tune.  Only my dogs will listen to my lyrics in some sort of multi-tone delivery.  The only song I can sing really well is Pink Floyd’s “One of these Days”.

For commercial, ACEEE’s tune is completely in line with recent post “End of Lighting”.   Cost effective LED lighting is not there yet in terms of cost effectiveness as an alternative to linear fluorescent sources.  Wonderful.  Instead, pay dirt is in systemic designs that a simpleton could not mess up.  These include single zone systems such as ground source heat pumps, variable refrigerant flow, and “efficient” rooftop units.  Papers presented on our website and one presented at the ACEEE Summer Study, as luck would have it, are available for more detail.

They go on to say that for new construction “design tools and standardized designs of common building types have been developed to achieve higher performance for a greater number of new buildings.”  Well, by golly!  This too sounds familiar.  However, I would add that programs need to foster and guide market players through these cookbooks as normal people, including contractors, don’t live and breathe energy efficiency on a daily basis.  The options need to be boiled down into distinct recipes for design builders for construction.  There are also, as outlined in the above linked ACEEE paper, systems that should be avoided because they are easy to dork up operationally, and there are others for which efficient heating and cooling sources are just not available in the market.  These include packaged rooftop units, which serve something like 70% of commercial building space in the country.

Continuing on with existing facilities, ACEEE promotes systems commissioning, retrocommissioning, and “strategic energy management”, the definition for which can be boiled down to setting targets, working toward them, and keeping an eye on things.  Yes, indeed, these are no brainers, but not normal.

Commercial buildings can be split into two groups: those for which there are great energy-saving opportunities and those that have little opportunity.  The latter group is cheating.  They don’t provide ventilation.  They may not have air conditioning (lots of schools in the Midwest).  They simply don’t maintain facility spaces meeting ASHRAE standard 62 ventilation and ASHRAE standard 55 comfort conditions at all times.

Similarly, ACEEE says the big money for energy savings for industrial end users is with process optimization.  I would add to this supporting system optimization.  Industrial customers are extremely reluctant to mess with their direct process, as this could affect their product quality.  Instead, typically a huge amount of energy is consumed and wasted by supporting systems: cooling water systems, fans, pumps, blowers, refrigeration, compressed air, as a few examples, and especially the control systems that serve these systems.  They say the next generation of programs must move beyond equipment replacement – well, hallelujah!

Lastly, just as I mentioned in November, utilities, but especially regulators, need to get off their fuel-switching-fixation horse and promote programs like combined heat and power (CHP).  As ACEEE states, backing my post, CHP reduces costs for all customers.  Possibly, they explain why in the rest of their tome, I explained why in Bait and Switch.  Nearly all new power generation plants are fueled by natural gas.  They generate electricity and dump huge amounts of heat to the surroundings (rivers, lakes, air, whichever the case may be).  The conventional wisdom is that CHP incentives for electric customers would benefit gas utilities by driving up gas demand.  Oh really?  Where does the electricity otherwise come from anyway?  Natural gas![1]  Get over it.

For this week’s “I told you so” finale, The Wall Street Journal reports that the budget deficit for the first quarter (October-January) shrunk compared to a year ago, “partly as a result of a surge in individual income-tax revenue in December.”  And, “The revenue boost might have been a one-time event. The Congressional Budget Office earlier this week said an increase in withholding taxes in December might reflect early payment of some compensation, because people were anticipating higher tax rates in 2013.”

Just following through on a promise from a mere three weeks ago, taxes matter.

[1] On the margin that is, and on the margin is where utility programs operate.  It’s all about the last kWh or kW to be provided.

Old School EE

Energy Efficiency, Government, Retrocommissioning (RCx), Tax Stuff, Uncategorized, Utility Stuff0 comments

Forging on from last week’s Arthur Fonzarelli crash into Arnold’s chicken stand, this week I will posit some challenges and problems presented with state takeovers of energy efficiency programs.  Per last week’s post, Wisconsin has fallen from 8th place in the nation to 17th place since the state essentially took over its energy efficiency programs.  This is according to the American Council for an Energy Efficient Economy, ACEEE, a well respected national think tank (my term) and advocacy organization for energy efficiency.

One problem is the money moves further away from where it is collected.  The further program spending is from the point of collection, the less care there is in its cost effective investment and avoidance of waste.  This is natural, and it is a fact.  A local, charitable non-profit is going to more carefully spend its money because local donors are right there to see the results for themselves.  If they want continuing donations, the local charity will be very frugal.  Moving on to local government, citizens know school board members, city council members, county commissioners, and so forth.  Do you think these representatives are going to be a little more sensitive to their largess when constituents may verbally tear them apart while filling up the tank at Kwik Trip or blast them in front of everyone at the next board meeting?

On the other end, taxing and spending at the federal level comes with very little accountability or care.  We have revenue rolling in from all over the country – income, payroll, Medicare, excise, corporate, and a few dozen other taxes and fees – and we have spending at 1.5 times that rate all over the world.  Spenders don’t care about taxpayers because they are not personally confronted by them.  The people responsible are insulated like mob bosses.  Write to one.  You’ll get a form letter describing how great their legislation is on an unrelated topic.  Nice. Have you ever been around a US senator or house representative?  They ooze with goo, and slide like (per my Tennessee friend) a greased eel in a barrel of snot.

When money is collected by a utility and spent for its customers, there is clearly more responsibility in spending that money.  For one thing, they are under the eyes and thumbs of the regulators.  They are in Wisconsin too, but the regulators hand pick the administrators, and thus there is an inescapable bias – like what is the best car on the market – mine because I selected it and I’m smart.  It’s human nature, man.  That’s all I’m sayin’.

Utilities have relationships with customers, and those are very important to the utility.  For state-run programs, not so much.  This presents another round of challenges.

First, good account managers understand their customers’ businesses and needs.  They are a tremendous resource and lever in a utility-run program.  With utility-administered programs, money is budgeted for account managers to assist with energy efficiency projects, so they are deeply involved in many cases.  For state run programs, not only is the budget absent, there is no carrot (goals) for saving customers’ energy.  Account manager time is extremely taxed so if it isn’t part of their responsibilities, they simply will not / cannot help.

Another result of not understanding customer business and needs is a lack of deep, structural, and lasting energy efficiency planning.  It is akin to the difference between long-term planning for a small business such as ours versus hitting quarterly earnings targets for a large corporation.  There is a huge difference between twisting a customer’s arm to replace all their lighting and throwing some program money at them, versus digging in and solving problems, reducing maintenance costs, improving productivity, and increasing profits and operating income – and maintaining and in fact continuing down the road.  Account managers live for this stuff.  We live for this stuff.  Persistence!

As alluded to in last week’s post, Wisconsin’s programs are low-cost and widget[1] based.  The programs are very similar to those in Illinois and Michigan.  Recall that while Wisconsin slipped from 8th to 17th since 1998, Michigan climbed from 46th to 12th (ouch).  Michigan also has low-cost widget based programs, but Michigan is very new to energy efficiency (and programs are run by utilities).  Conversely, Wisconsin represents a very mature market for EE.

Meanwhile, utilities in neighboring Minnesota and Iowa, two other mature markets, have moved on to successful industrial, process, retrocommissioning, and new construction programs for commercial and industrial customers.  They have vibrant energy analysis programs to assist customers with identifying, planning, and prioritizing implementation of cost effective measures.  Wisconsin point-blank shuns this sort of informational / road-map assistance to guide complex customers to higher profit and improved cash flow.

Furthermore, where utilities own the programs there is de facto competition among them to look good to their customers and to the regulators.  There is vibrancy.  Things change.  Things improve.  They have to keep pace.  They want to be better.  In absence of this: same old, same old, until the entire state is compared against others and then the results aren’t liked.

In my 17 years in the business, I can tell you the days of en masse studies and energy audits rotting on the shelf with no ensuing action; and customers not caring about energy cost and not viewing energy as a strategic resource have changed dramatically.

We were even told by one of our major utility clients in a neighboring state that their management sees energy efficiency as a source of income rather than a “red headed stepchild”[2] as it used to be viewed.  Times have changed, dramatically.  Like Dan York from ACEEE mentioned in his letter to the Cap Times, “neighboring states rank higher than Wisconsin because they continue to push for higher energy savings through increased investments in energy efficiency. Wisconsin, by contrast, is standing still and by doing so, is getting left behind”. 

[1] Widget-based simply means standard option A versus more efficient, somewhat more expensive option B.

Being a critic and a manager, I always love it when somebody else does my work for me and I can lay low, because I often feel like a grumpy old man.  For example, some of my guys are tougher and harsher than I am on issues, people, and their work both inside and outside the company.

On a related note, there is a big difference between whining and complaining.  I use a more vivid term for the latter, and I’ll leave it to the reader to guess what that is.  How does one define the difference?  The difference is whining has a woe-is-me connotation, and “me” has not done, and is not doing anything about it.  “Me” has not suggested alternatives, made any changes, taken the snake by the fangs, talked to the right people, voted, written letters to the editor, met with the person they’ve had a grievance with, and so on.  Instead, “me” whines to people who have no control over the situation, say a spouse.  Can you relate?  One of the Tough-Mudder pledges includes, “I do not whine.  Kids whine.”

Kids are allowed to whine because they are not mature enough to live with the consequences of bad decision making.  It’s for their own good.  Parents set the rules and therefore parents must be petitioned for changes.  Come to think of it, this isn’t whining at all.  Go for it kids.  You are clearly qualified and in the right position to complain to parents incessantly, and per definition, tell the ignorant parents they are directly responsible for your oppression.


The American Council for an Energy Efficient Economy (ACEEE) recently issued their state by state report card, and I didn’t pay that much attention because things don’t change a ton from year to year.  However, one thing I checked on is Wisconsin’s standing since Focus on Energy (FOE) began.  For those who don’t know, Focus on Energy is Wisconsin’s state-run energy efficiency program portfolio.  Back in the 1990s the stakeholders thought deregulation was going to sweep the industry and there would be competition for electrons.  And although there would be alternatives, Wisconsin, as did some others[1], took programs away from the utilities and centralized it to the state level.

Wisconsin’s first giant mistake was to have a major branch of the Wisconsin State Government be responsible for the program.  I believe that was the department of administration.  Shortly after going statewide with the pilot phase, the governor and legislature raided the cookie jar and eviscerated FOE when the first budget “crisis” hit as a result of the recession preceding the current never-ending one.  Then it moved under the purview of the Public Service Commission (PSCW) to shield it from cowardly lawmakers.

Nevertheless, since just before FOE (1998) to present day, Wisconsin has fallen from 8th in the ACEEE ranking to 17th.  It is dead last among neighboring states: MN-9th, IA-11th, IL-14th, and MI-12th.  I noticed Michigan was ranked 46 in 1998!

Ok.  I wasn’t going to point this out in this blog, except for a letter to the editor from ACEEE’s Dan York, published by Cap Times (Capitol Times – Madison).  Mr. York did my work for me as described above.

A spokeswoman for the PSCW claimed FOE has fallen behind in spending but not in results and therefore, ACEEE’s rankings were wrong.  Mr. York responded with the smackdown letter to the editor, stating that ACEEE incorporates both spending and results into its rankings, and he also thanked Wisconsin for paying attention.

What is the problem?  Cue up my opinions.  While the program has moved out of direct control of lawmakers and the administration, it still has a heavy dose of political influence.  I have met and know, to some degree, especially with reinforcement of many, many people in the industry, the staff at the PSCW.  While I have some disagreements with their views, this I can say: they clearly have the best interest of the state in mind, and in fact, at the top of their decision making processes.

Does anyone need examples of problems with the political system?  Per Winston Churchill: “…it has been said that democracy is the worst form of government except all those other forms…”.  A few keywords and phrases regarding our political system/democracy: endless protesting, tea party, senators hiding out at Super 8 in other states, occupiers, budgets not being passed for four years, totally partisan legislative voting.

I have no evidence of PSCW staff being politically influenced, but the commissioners themselves are political appointees, “serving”[2] at the pleasure of the governor.  I do not know how, when, or for how long commissioners are appointed, as I know for the US Supreme Court (SCOTUS).

Anyone think even SCOTUS is blind to ideology?  Everything SCOTUS decides is personally and/or politically motivated.  If justice were blind, many decisions would be 9-0.  Instead, decisions are massively partisan.  A couple courts ago, we could just get rid of eight judges that always split the vote 4-4 and keep Sandra Day O’Connor, the “swing” vote.  More recently, just keep Anthony Kennedy, the swinger.  The point is, partisanship seeps into everything at state and federal governments.  This is a problem, and there are others as well.


I haven’t watched prime time TV for 25 years at least, but I remember an episode from Happy Days, ironically set in Milwaukee, when The Fonz was having an identity crisis and he had to recapture his cool by jumping 14 barrels or something stupid like that.  Complete with drum roll, just as he cleared the ramp, they cut it off, “To Be Continued” for next week (when he crashed into Arnold’s chicken stand).

To be continued.

Lessons from NYC Benchmarking

Energy Efficiency, Utility Stuff0 comments

New York City recently completed its report for the benchmarking of all its “large” facilities, generally with square footage of 100,000 or greater.  The results of the study are not surprising.  You may be thinking, “Who cares about NYC?”  Answer: this post includes universal challenges with benchmarking whether it’s Batswana or the Yukon.

The benchmarking was completed using ENERGY STAR Portfolio Manager, which as far as I can tell ranks buildings by source Btu[1] per square foot, otherwise known as energy intensity.  For example, it uses a factor of 3 for electricity, which is one over the efficiency of delivering electrical Btus to the site.  In other words, it takes 3 units of energy from coal, natural gas, nuclear fuel, etc, to provide one unit (Btu) of electricity.


Finding #1:  Energy intensity varies all over the place, by factors of 4:1 to 7:1 depending on building type.  Buildings at the high end of energy intensity consumed 4 to 7 times more energy per square foot than miserly buildings.  This is not surprising and can be due to a myriad of factors.

  • First, energy intensity can vary by a factor of three between misers and hogs.
  • Second, some may be “cheating” because they provide no ventilation for their occupants.  You know, clammy caves.
  • Third, some buildings may not be fully occupied, although decent benchmarking should account for this, but it’s still a crap shoot.
  • Fourth, some buildings are difficult to classify – they may legitimately have five building types – retail, healthcare, residential, office space, and lodging in a single facility.
  • Fifth, there are plenty of places to screw up and make mistakes.  More on this later.

Finding #2:  Older buildings have lower energy intensities.  This is consistent with a white paper I wrote a little over a year ago and with a related paper presented at the American Council for an Energy Efficient Economy (ACEEE) Summer Study for Buildings last month.  Stunningly, the energy intensity by building vintage in five categories decreases in each step from newer buildings to older buildings.  Older buildings use less energy.  There are no hiccups.  The reason is, HVAC designers lost the forest amongst the trees, started going down paths of centralized heating and cooling systems that are terribly complex and poorly understood.  See the papers noted above.  Older buildings may, for example, have window air conditioners with horrible efficiency and old steam radiators, but they damn well have the radiators off when it’s hot as blazes outside and the window shaker is running.  This is typically not the case with the newer Rube Goldberg colossi HVAC systems.  It would be surprising to not have cooling at the central air handler and some heating going on at the occupied space even when it’s 85F outside and the humidity is thick as a stick of butter.

Finding #3:  NYC buildings are more efficient than others in the nation.  Haha, har har, hardy har har.  I don’t buy this at all.  The results may say so, but first the data set for comparison is almost 10 years old, from 2003.  But you just said Jeff, that new buildings waste more energy.  Yes, but not many buildings adding to the “new” (post 1960) have been built in that period, and secondly, energy use in buildings tends to rise with rising plug loads and associated energy required to offset those loads (cooling).

Finding #4:  Apartment buildings have a smoother and narrower (more uniform) distribution curve than office buildings.  Again, this gets back to the single zone systems one is likely to experience in apartment buildings versus the enormous variation of systems one would see in these office buildings.  The single zone systems provide heat or cooling and not both at the same time.  This results in two things: lower energy use and more predictable energy use.


Cited Challenge #1: Building square footage.  Yes, this can be challenging, but it is easy compared to other challenges that weren’t noted.  These include the usual cases where one meter – electric, steam, chilled water, and/or natural gas serve more than one building.  E.g., district metering.  How were these allocated?  Conversely, many times buildings have multiple meters, sometimes for logical reasons such as additions. At other times, a large gas supply to a boiler plant may be interruptible and there may be a second meter serving a kitchen, and that is on firm / non-interruptible.

Cited Challenge #2: About 100 consultants provided the benchmarking services and data.  Whoa!  Thirty firms did most of the buildings.  Nevertheless, I can all but guarantee some of these firms have no business providing these services.  Benchmarking is like chiropractic or physical therapy.  You need to read the symptoms (building characteristics), assess the patient (energy data and how it matches what you see and hear), and use subtle tests to confirm your findings – does it make sense?

Cited Challenge #3: A compilation of stuff I noted above with multiple buildings served by single plants, utility meter data by service address and not by facility (difficult to match meters to specific facilities), having a building address with no matching meter address, and so on.

Learning Curve

All credit to the auditors and authors.  They have recognized the data as a bit shoddy and unreliable and thus it will not be made public on a building by building case.  My humble suggestions would be to sharply reduce the number of benchmarking companies to a handful that really know what they are doing.  While it is always far easier to recommend than do, give them access to utility customer information systems so they can investigate meter discrepancies themselves.  This is not intern work or work for statisticians or MBAs.  It requires experts with a long track record of evaluating facility fingerprints and recognizing whether the energy data provided is the right data, all the data, and only the data that applies.

Delta Lambda Jamba Effect

Energy Efficiency, Utility Stuff0 comments

I was recently pushed over the edge again by multiple opinion pieces declaring that energy efficiency is a waste of time and money because of rebound effect.  Rebound basically means that if consumers buy an efficient appliance, car, or light bulb, they will simply use it more and therefore save less, or even use more energy at the proverbial “end of the day”.

First in this series was an opinion piece from a Cal State Fullerton professor published in The Wall Street Journal.  Below is my response to the journal:

Robert J. Michaels’ commentary on August 20th suggests energy efficiency does not capture estimated savings from widgets (lights, air conditioners) because of rebound effect, which put simply is the theory/fact that lower operating costs of widgets results in more widget use.  No one, including the fast growing energy efficiency industry, disagrees with rebound effect.

However, Mr. Michaels uses a Mexican refrigerator program example to demonstrate his point.  Why not use an example of delivering subsidized Toyota Priuses to the rural Chinese?  Certainly a Prius uses more gasoline than a moped or a rickshaw.  He dismisses out of hand a recent rebound study performed by the American Council for an Energy Efficient Economy because it “examined only a minority of rebound findings…”  [If only we could say with such ease that some of the stuff we review during program evaluations is totally bogus…]

Energy Efficiency Resource Standards produce real results.  Standards in many states include targets that actually reduce total energy consumption, and they are being met as evidenced by independent third party evaluations.  Energy efficiency, and its cousin demand response, are used as virtual power supplies to sell into forward capacity markets, including those on the east coast and northeast.

Electric utilities are more or less regulated monopolies, and as such regulators need to, and do a good job of balancing the needs of consumers (low energy cost) and the needs of utilities and their shareholders (return on investment).  The regulatory model to date has relied on ever growing sales and profit.  However, with energy efficiency slowing, and even reversing revenues and profits, this model will need changing in coming years.  One of our recommendations is to allow utilities to invest in energy efficiency on the customer side of the meter and earn the same weighted cost of capital as they would with new power plants.  Another is “decoupling”, which allows utilities to maintain return on fixed costs of power plants and distribution systems while sales decline.

Energy efficiency is no longer a hobby for geeks and hippies.  Large multi-national corporations including food processors, auto, appliance, high technology, household products, and diversified product manufacturers are investing heavily in energy efficiency to be competitive, reduce risk of energy price volatility, and of course immediately hit the bottom line.  Even commercial real estate and multi-family housing owners are wising up to the capital generating capacity of energy efficiency in their facilities.  This wouldn’t be happening if Mr. Michaels’ theories were accurate.

As mentioned on this blog one time recently, who buys a dinky car with good mileage to drive it more?  Nobody.  Dinky cars are tools to get from A to B.  They are not recreational vehicles.  When people buy efficient air conditioners they don’t get the urge to keep their house at 57 degrees in July.  A new refrigerator isn’t going to be set to 30 degrees or have its door held open to view the contents for long periods of time.

One effect of having more money left in consumers’ pockets is they may buy more stuff, which takes energy to produce, transport and use.  I’m sure there is some of this, but parents may also decide to send their kid to Columbia rather than the local community college with the savings generated from their new clothes washer.  Does that consume more energy?  No.  The kid flies to New York and back a couple times a year rather than driving to the community college every day, thirty miles round trip, with dad’s 14 year old gas guzzler.

Or, did they ever think of this?  Savings from new windows result in enough free cash flow to replace the energy guzzling TV with a new efficient one.  I.e., the opposite of rebound is also true in many cases.  Earnings generated from the first wave of energy efficiency measures finance the next round.  In fact, I’ve actually demonstrated before that energy guzzling buildings have an easier path to real energy independence (net zero) because they have an enormous flow of cash going out the door each month to pay the electric and gas bills.  Redirecting this hemorrhage to energy efficiency accumulates so much cash that eventually the money that used to flow to the utility can be used to purchase on-site renewable energy AFTER the much more cost effective EE measures have been implemented and paid off.

What is the opposite of rebound?  How about slam dunk?  Let’s call it the “delta lambda ja

A Radical Idea

Energy Efficiency, Government, Tax Stuff, Utility Stuff1 comment

This week I was gleeful to find American Council for an Energy Efficient Economy released a study on my two favorite subjects on which to rant: taxes and energy efficiency!  Yeah!

I blogged about tax-distorting effects of EE about a year ago in EE V IRS,with many of the same arguments noted in the recent ACEEE paper.  The ACEEE paper points out that:

  • Since the cost of energy is a business expense, it is tax deductible and therefore, the tax code penalizes to the tune of 35% the bottom line improvement from saving energy.  As I mentioned in EE V IRS, the United States had the second highest corporate tax in the electrified world and this week; congratulations (!), we’re number one as Japan has dropped theirs below ours.
  • On the flip side, when companies invest in EE, 35% goes to the government.
  • The EE investment is depreciated over time.  This I discussed last week in Petroloons .

First, one sharp criticism of the above logic: not taking is not giving.  In other words, avoiding tax payments to the government is not the same as getting something from the government.  This drives me crazy.  It’s the same as saying I give our company a case of soda every day because I haven’t been shoveling the contents of our soda cooler into my bag every night (steeling it) for myself.  Do murderers save the lives of everyone they don’t kill?  Ok.

Jack Kennedy was absolutely correct stating that cutting and simplifying the tax code results in efficient allocation of capital.  Today, the tax code is corrupting with carve outs, societal engineering, and tax breaks for all kinds of crap that ties capital up in stupid stuff.

The feds tax repatriated capital, that is, money earned by US companies overseas and already taxed overseas by countries in which they operate.  This is insane.  Bring cash back home for investment and it first gets a 35% whack taken by Uncle Son of Sam?  Washington likes to bash these companies for doing stuff overseas and the “tax breaks” they get for moving jobs overseas.  The “tax break” is not getting slapped with a double tax.  Not murdering is not the same as saving lives.  Ok.

Another distortion is tax on capital gains and dividends.  Trillions of dollars are parked in stupid stuff, like Apple’s $100 billion stash of cash.  Why such a ginormous pile of cash?  A major reason is shareholders don’t want to pay tax on dividends.  Likewise, capital in equity in mature companies and starving the next generation of wealth creators.  When an investor considers a 15% loss right out of the gate by divesting one place to invest in a better place, 15% is a huge barrier.

Any tax reform must lower barriers between capital and where it is best invested.  This is what JFK meant by efficient allocation of capital.  Now, on with the three ACEEE recommendations:

  • Tax revenue, not earnings – a “radical” idea.  Actually, this would be a sales tax or value added tax.  Eliminating the current abomination and switching to a revenue neutral sales tax would be fantastic for the economy (and ¾ of Washington DC lobbyists would find themselves out of work).  Capital would flood into the country and be cut loose from unproductive proverbial stuffed mattresses.
  • The second is a “more surgical” approach that puts a cap on tax deductable energy costs.  Bad idea.  This would penalize energy intensive companies and distort the market again, nudging companies that produce jobs overseas.
  • The third is a “more complex but perhaps more elegant approach”.  Complex to me is butt opposite of elegant, but ok.  This option would develop a standard deduction for energy costs that varies with the type of business.  Screeeeeeeeeeaaaaaaaaach!  Needle across the record.  This again would be a market-distorting, game-the-system, screw-the-system approach akin to Rick Santorum’s proposal for zero income tax for manufacturers.  Suddenly, everyone is a manufacturer.  How does one define manufacturing?  Is a brew pub a manufacturer (hardly) or a service company?  Is printing manufacturing?  We print stuff for sale.  You get the point.  Just imagine if we set this tempest loose.  We should be generating wealth and not playing games to avoid the taxman.

Jeff Ihnen’s solution:  Create revenue neutral tax cut by eliminating all market distorting tax breaks and carve outs, and eliminate the double taxation on repatriated greenbacks (I believe this was in the Simpson-Bowles committee that was/is entirely ignored).  Here is a “radical” idea: let utilities invest on the customer’s side of the meter.  Energy efficiency is a resource.  There is concern about the old utility business model based on a forever growing market that doesn’t work anymore (because the market isn’t growing).  So let’s allow utilities to invest in energy efficiency on the customer side of meter and let them earn their weighted cost of capital as they do selling energy.  This fixes the problem of losing revenue and profit to EE and greatly reduces the tax-distortion and hassle of EE by making EE an operating expense rather than purchased assets.

Amen.  Where do we start?


Opt Out Ruse

Energy Efficiency, Government, Utility Stuff0 comments

In October 2011, the American Council for an Energy Efficient Economy delivered a report, “Follow the Leaders: Improving Large Customer Self-Direct Programs”.  But before I discuss/interpret that, what is a self-direct program?  Some large energy users wish to opt out of utility sponsored energy efficiency programs, and specifically they want to avoid paying the energy efficiency cost recovery rider.   This particular rider is a surcharge, similar to tax on gasoline that is supposed to be used for roads.  These large energy users state they can better invest this money in their own energy efficiency program – a self direct program.

On average, this rider may be 1% for an electric utility.  So a large energy user with an annual electric bill of $5 million would “self-direct” the use of the $50,000 they would otherwise pay to the utility to deploy to their own energy management program.  These customers think they can better invest their own money.  I would consider this an ignorant and unwise assertion and I’ll get to this later.

The executive summary of the report, summarized and paraphrased by me, provides no surprises:

  1. Only a small fraction of self direct programs capture savings that benefit all users as utility-run programs do.  Programs should benefit all customers, even non-participants.
  2. Provisions vary widely and some do not require any sort of measurement and verification.
  3. The majority of self-directed programs are poorly structured.
  4. Programs cannot claim to achieve the same bang for the buck as would be realized with the larger utility-delivered program.
  5. Self direct provisions are popular among policy makers.
  6. Long term impacts of these programs are unknown.
  7. Without oversight these programs are “unfair” to other rate payers.

My executive summary of the ACEEE executive summary:  Self direct programs are weak, sparing more vivid prose.

Let’s first address the reason these programs exist, which is summarized in number 5 above.  Opt out / self direct programs exist because lawmakers are beholden to large corporations (in this case, or unions in other cases) that don’t want to pay for these programs.  When necessary, upholding the political class trumps the best interest of society.  One doesn’t hold a seat in the House of Representatives for 50 years without playing by these ideals.  Term limits anyone?  How about logical, geographically random congressional-district boundaries rather than having those in power draw the lines (gerrymandering) to keep them and their party in power 10 years at a time?  Ok.  So I meander, but this is the root cause.

The “we can better invest our $50,000 than someone else can” argument is bunk.  Fifty thousand dollars may sound like a lot to you or me, but not for a political fundraiser or a huge facility.  For $50,000 one has to, presumably, write a plan, implement stuff, and evaluate with M&V.  This requires substantial effort and skills not possessed by large users.  As the report found, not going to happen.  These customers would do well to spend $50,000 on new equipment that they think might save energy.  Whether it would or not is another question.

Here is the bottom line – if these customers sincerely want to reduce their energy consumption and cost, they are foolish for opting out.  The truth is they are “not foolish” (get to this below) because they have no serious intention of spending that money on EE.  They just want to keep the $50k.  Opting out for customers that think they can better invest their own tiny bit of money is foolish for the following reasons:

  • Overhead associated with the program is borne by all rate payers.  There are enormous economies of scale.
  • Customers can get their money back many times over.  Smart companies, and we know many of them, regularly pull hundreds of thousands of dollars from these programs for implementing energy efficiency.  Some of these companies are publically traded and have great earnings.  Do you suppose there is a connection with being energy efficient, leveraging programs, and taking money from competitors that would rather opt out if they could?
  • They lack expertise, possibly with the exception of lighting, to know what their ROI numbers look like.
  • Huge customers WILL get the attention of their utilities and/or program implementers.

Huge energy users participating in EE programs should however, be allowed to get all their money back and then some.  In the example above, I use a $5 million customer.  Depending on the level of rider, a substantially larger customer with $20 million in annual consumption may be capped out by program limits.  Such a company that cannot recover their annual contribution to the program has a valid point.

A few other random comments from the report:  Three primary reasons large users feel obliged to opt out: (1) Programs are not responsive to their needs.  I doubt it.  See the last bullet above.  However, having evaluated many industrial programs, I understand this point in some cases.  To the hammer (program) everything is a nail (lighting), and that’s how they work – pretty weak.  (2) These customers have already implemented all cost effective measures.  (LOL) and (3) they are subsidizing other rate classes.  Uh huh, like I as a residential customer and tens of thousands of other customers don’t subsidize all rate classes too.

The report indicates that some states have “structured” self direct programs and shows which states those include.  I imagine ACEEE is reporting what they are told but we work in some of these states and the term “structured” must not entail hardly anything.  It’s one-way only feedback and don’t look behind the curtain.  In other words, we only get to review end-user plans that are opaque, vague, and vacuous and those go in a file somewhere – probably in the offices of the lawmakers who let them get away with this.  And, field investigations are not allowed.  If this is structured, what does the relaxed plan look like?

Great report.  Hats off to ACEEE.

Goats in Sheep Clothing

I could do an entire rant on this but it would require too much random research, so maybe I’ll pass these along as I see them.  I was reading a press release from an energy efficiency company I had known for a long time.  The “About ___” section of the press release says “___has been revolutionizing commercial and industrial facilities with proprietary energy management systems…”  I was thinking, wow, they must have moved beyond lighting because I thought they were “just” a lighting company.  Turns out, hell no.  Every single case study in their portfolio is a lighting project.  Energy management systems?  C’mon.  Energy management systems are synonymous with building automation systems, direct digital control systems – facility wide digital controls for HVAC converging to a computer and almost always accessible by internet.


On the informative front, Ceres, which I know very little about, released a report on utility EE portfolios nationwide.  Again, I’ve taken the data and merged it into a more telling story, at least more telling in what I’m interested in.  That is, cost effectiveness at delivering savings and ratio of savings to sales (relative savings).  The table below is sorted by relative savings.

I included the recent ACEEE rank for the states in which the utilities serve.  This provides some interesting insight as some large utilities that rank very high in relative savings were not viewed very favorably in the ACEEE analysis.  Bear in mind that ACEEE rankings are for entire states and include other metrics.  Interesting divergences include Nevada Power which serves nearly everyone in the state (3rd Ceres, 17th ACEEE), and Salt River – Phoenix (7th Ceres, 17th ACEEE).  The Ceres analysis indicates California (#2, ACEEE) towers over Massachusetts (#1, ACEEE).

Note however the states and utilities do not always align well, or there may be asterisks for some.  For example, Wisconsin Power and Light has a small fraction of the EE business in WI while state run Focus on Energy would dominate the ACEEE ranking.  Additionally, WP&L has only a commercial/industrial program.  Duke Energy is smeared across multiple states.  Note also that relatively tiny utilities in Texas are in the Ceres report while the giants are not, for whatever reason.

Regarding program spending per kWh saved, generally speaking where electricity costs are high (New England / New York), the cost to save energy is also high.  However, by this metric again, it seems California got a lump of coal from ACEEE compared to Massachusetts, which has much higher cost per kWh saved, and I don’t think the energy costs are that disparate among the two.  Also, generally speaking, states and utilities that have had programs a long time (the easy stuff is gone), have somewhat higher cost per kWh saved.

Electric Bills and Waldo

Energy Efficiency1 comment

Recently, the American Council for an Energy Efficient Economy issued a report, “The State of the Utility Bill” and I thought, “now there is a topic for plenty of discussion.”  No, that was no joke, although there was an interesting finding that I found to be very hilarious:  All of the ~100 bills analyzed in the study (100%) included the amount due to the utility from the customer.  I would say not having the amount due would have its disadvantages.  (that WAS a joke)

I’ve witnessed and studied many issues regarding end user understanding of energy, energy consumption, and end uses – e.g., lighting.  Our industry reminds me a bit of the political talking heads on TV.  They hyper analyze things for which only they or a political news addict, and not the common voter is going to notice or care about.  An example might be a response to a question on a hypothetical crisis in the Middle East.  The pundits will quibble over the order of responses or their indicated aggressiveness as suggested by the candidate or even the question.  Meanwhile, the average viewer is looking only for whether the recommendation would include blowing the enemy  to kingdom come, finger-wagging sanctions, nothing, or withdrawing from the region altogether.

Likewise, there is a disconnect between what we think end users think or know and how they actually think and what they know.  The utility bill is damn complicated to the average end user and even more so than the average energy professional realizes.  The bill might include different seasonal rates, tiers, time of use, demand charges, ratchet clauses, and even more complex algorithms.

I learned long ago that when we need energy records for a customer, the best form is to get copies of actual bills and a close second is the utility’s CIS (customer information system) data.  When the customer says, “Oh, I have all that in a spreadsheet.  I can just give that to you.” I cringe because they won’t have what we need or it will be wrong because they can’t pick the right numbers off the bill – like finding Waldo.  I don’t want it.  It’s virtually guaranteed to be wrong.

The ACEEE report indicates just over 90% of the bills include comparison to the previous month’s consumption.  I can’t find that Waldo on my bill.  I do have comparison to year-ago consumption, the next most common element found in the study.

Average daily usage.  Now what does that tell anyone?  Anyone?  It doesn’t even tell me anything, except that’s the form in which I am provided for the comparison to last year.  I did buy a $9 retractable clothesline from Menards a few months back and it looks like our bills are very roughly 4 kWh lower per day versus the same year-ago period.  Of course air conditioning is mixed in and that’s a monkey wrench.  However, they provide average temperature, which is reported to be provided on only 38% of bills per ACEEE.  I could do a weather calibration for that.  However, I know that is a waste of time because there are other substantial factors – weather independent end uses – that will result in any weather adjustments being far down in the grass of normal usage variation.  How about that?  There is enough information to do a weather adjustment, which only  1% of customers MAX, could mathematically do, and of that 1% probably only 10% know weather normalization is a waste of time for a single energy bill.  (single, not aggregate for a representative sample of a bunch of customers)

What would be useful is a monthly bar chart including the trailing 24 months with overlapping years for monthly comparison.  Neither my gas or electric bill has this but my water bill does!  Good grief, I buy electricity from a huge utility, natural gas from a dinky regional supplier and I get water from my village – population of the metro area is about 800 (this includes all the zeros – no typos or omissions).


Benchmarking provides incredibly useful information.  Yeah.  Let’s do that.  The state of Iowa is wanting to do this for (I’m not sure exactly) government facilities including schools.  There was an RFP and one (1) proposal was received.  Why exactly, I’m not sure but I would say this – I would guess the buyer does not understand how difficult it is to do benchmarking right.  It’s like recent rants where I said even measuring ambient outdoor temperature is difficult and the person doing it has to know what they are doing and literally understand heat transfer, including primarily radiation from surrounding objects and convection off the same objects.

Benchmarking requires knowing the type of heating and cooling systems and more specifically, the heating and cooling fuels, square footage, and of course utility consumption.  The guy doing the benchmarking has to know whether the results look reasonable.  The following are my unscientific estimates for how many benchmarking analyses would be correct for the following methods and skills of the benchmarking guy.

  1. Blindly collecting square footage data and energy consumption with no ability to do even a laugh test: 35% correct
  2. Number 1 but throwing out anything that looks really weird, like 50 kWh per square foot for a school or 0.15 therm per square foot for a hospital: 45% correct, not to mention a great many will be discarded
  3. Number 2 plus contacting the utility to make sure you have all the data for the facility.  Many times benchmarking is wrong because there are data missing because not all meters serving the building are included:  55% correct
  4. Number 3 plus calling the customer to ask them about their heating and cooling systems and fuels used for these systems:  75% correct
  5. Number 4 but rather than doing a phone call, going on site and looking for meters and systems yourself ensuring you have all the meters serving the building and only the meters serving the building:  92% correct

There you have it.  If an experienced expert can do everything in his/her power, there are still things that may not be able to be benchmarked with confidence due to:

  • “Campus” meters – here campus being any meter serving multiple buildings (k-12, college/university, health care, military, and even corporate) without submetering on each building.
  • Storable fuels like propane, fuel oil, and chicken manure.  Tank levels and piles vary from month to month and so determining consumption requires accurate levels plus deliveries.
  • No meters – what are you talking about, Jeff?  Steam coming from a campus plant with no submetering.  You can know how much natural gas the central plant uses or you can guesstimate the consumption eying the pile of chicken manure (or coal) and tracking deliveries.  Old central steam plants for example can have rather enormous heat losses to pipe tunnels, making for melted snow and green grass in winter.  A good bit of analysis is required to weed this out.

I avoid requests for proposals where I don’t think the buyer understands how difficult it is to do a job I can live with and for those RFPs there is always an ignorant bidder who doesn’t know the difference.  Unfortunately, there is no money in telling the buyer what they are asking for is very difficult and that they are going to get crap for results from Cliff Clavin and Associates.

One more thing on benchmarking, total Btu per square foot, mixing all fuels together is a little better than nothing.  Electric should always be separated from fossil fuel consumption.


  • The incandescent ban advocates are proposing a switch to using lumens as the metric for selecting light bulbs for purchase at your favorite home improvement store. Uh huh.  Around 1980 the US was going to be the last country on the globe to convert to metric units.  You know base 10 everything with common sense conversions like a milliliter equals a cubic centimeter.  Fuggeddboutit!  Not gonna happen.  There is plenty of fodder for a stand alone rant on this one.
  • ACEEE in their Utility Bill study noted above calls utilities “regulated monopolies”.  Cool.  This is what I’ve called them for years and didn’t know whether this was offensive to them.
  • Lastly – another mind blower – the US is set to become a net exporter of refined petrol products.  This is good news if you ask me –a strong manufacturing sector.  To clarify just in case – yes, this is refined petroleum products and not crude oil.  Many readers were ranting this is misleading – only to a dolt.  Plot and data courtesy, The Wall Street Journal.


Efficiency, Politics, Policy, and Economy

Energy Efficiency, Government0 comments

Recently, the American Council for an Energy Efficient Economy (ACEEE) released its annual state rankings for energy efficiency.  We noticed Wisconsin slipped a few pegs to 16 while Iowa remains near the top at 11.  The top states for EE programs include the usual suspects: California, Massachusetts, Vermont, and New York.

As we discussed the rankings in house, my comment was, you probably don’t want to be in the top 10 on this list because those states are on the business-unfriendly end of the spectrum.  They have big EE spending congruent with heavy regulation.

So you guessed it; this rant analyzes economic performance, politics, and business friendliness along with the ACEEE rankings.

I did some digging to see what sort of correlations there were between state energy policy, political leanings, and economic growth.  One can make all sorts of arguments; my favorite including “if it weren’t for xyz, it would be much worse.”  But I never buy that bologna.  Likewise, I don’t buy excuses for why savings aren’t being accrued as estimated, unless something radical has changed – like half the occupants left the building and turned out the lights.  This is why we look at savings on energy bills and don’t bother with weather normalization or other excuses.  Nobody can argue with meter reads from billing data.

I used growth in gross state product for the past 10 years as a metric for economic vibrancy.  I used the average percentage of votes for Democratic candidates for president over the past four elections as a measure of state political leanings and simply ranked those from low to high.  Finally, ranks states for business friendliness with a survey of about 550 CEOs.  The CEO rankings include considerations of tax and regulation, workforce quality, and living environment.

The rankings for all categories are shown in the data at the bottom of this blog so you can peel it off and do whatever you want with it.  FYI – I left out District of Columbia because that is a whacked out, in more than one way, “state”.  Therefore, you will see some 51s in the scatter plots.

Plots are worth a thousand words so I plotted ACEEE ranking against political leanings and ACEEE ranking against economic vibrancy.  There is a strong correlation between energy efficiency policy and the states politics.  Liberal states dominate the high end of the ACEEE rankings as shown in the chart below.  Bear in mind that low numbers are high rankings.  For example, see the first dot in the lower left corner of the plot.  That represents Massachusetts, which was ranked number one by ACEEE and the state has the most liberal record in presidential elections.

It is interesting to point out the outliers.  The most conservative state is Utah and they have an ACEEE ranking of 17.  Idaho, the third most conservative state is ranked in the middle at 26 by ACEEE.  On the other end is Delaware, the 10th most liberal state with an ACEEE ranking of 31.  Delaware, however is the size of my back yard and has almost no Interstate highway so anything is possible there.

To my surprise, there is a very weak correlation between energy efficiency and economic growth.  It’s actually better than I thought because big states like California and Michigan have good EE rankings and horrible economies.  Generally speaking however, higher EE rankings have less economic growth.  This is what I was referring to regarding not making excuses.  But..but…but…  I don’t care.  It is what it is and you can send your excuses to your senator where it can be ignored with the rest of the correspondence he/she gets.

See the first point on the left in the chart below?  That’s Massachusetts, which had the third worst economic growth over the 2000-2010 period.  Yeow!  That crappy growth was a bit of a surprise to me.  California was 34th in economic growth – actually considerably better than I would have guessed.  Subtract Apple from the state’s GSP and it would probably be 45th place.  Subtract the rest of Silicon Valley and it would be 50th I would bet.

Washington (the state) has the best combination of energy efficiency and economy.  Missouri appears to be a convincing dead last in this combination.

Actually, when I said the second quintile is probably where you want to be from an EE perspective, I was correct, somewhat.  The second quintile of states for high EE ranking have the second worst economies, but better than the first quintile, bogged down by rust belt states of Michigan, Wisconsin, Illinois, and New Jersey.  Actually, the states with the worst EE rankings have the best economies, so I was right in that sense, unfortunately.

Finally, I roll it all together: energy efficiency, CEO business friendliness, economic growth, and political leanings.  Once again, I remind you that large numbers are low rankings.

First a few comments on business friendliness.  Texas is top ranked by CEOs as the best place to do business.  California is dead last.  In a post a few months ago, I pointed out the hilarious fact that Gavin Newsom, California’s Lieutenant Governor, with several legislators in tow visited Texas to see why Texas was sucking jobs out of California like a Hoover vacuum cleaner.  What a dope.  Maybe he should discover this thing called the internet.

When considering workforce quality and living environment have to be sky high for California, you know their tax and regulatory climate is hell on earth.  Steve Jobs apparently alluded to this in his recent biography by Walter Isaacson, saying “it is almost impossible to do so [build a factory] these days in America, largely because of regulations and unnecessary costs.”  For examples, Google “delta smelt” to see how “saving” this minnow ruined farmers in California, or check out this recent article to “save” a sucker (a fish that is) in Southern California.  There are a plethora of states that would be happy to export some Asian carp to replace this bottom feeder if that’s what they want.

But on with the comprehensive results shown in the chart below – Based on trailing economic performance and current energy efficiency and CEO rankings representing future potential, it appears that the fourth quintile of states ranked by ACEEE is the optimal place to be.  These states include Indiana, Texas, Virginia, Montana, Georgia, Kentucky, Alaska, Arkansas, Louisiana, and Nebraska.  These states are ramping up EE programs.  The average CEO rank for future business development of top EE states is almost 40.  That is terrible!  These states include Massachusetts, California, New York, Oregon, Rhode Island, Vermont, Washington, Connecticut, Minnesota, and Maryland.

But…but…but – I don’t care.  As my basketball coach used to say, “If ifs and buts were candy and nuts what a wonderful world it would be.”



State by state data are provided below.

GSP Rank = ranking in growth of gross state product from 2000 to 2010, constant dollars.

CEO Rank = survey results of 550 chief executives for business friendly states considering taxes, regulation, workforce, and livability.

Democrat Rank = Ranking of states by percent of votes for the democratic candidates in general presidential elections for the trailing four cycles.

Obviously, many states have tied scores for ACEEE.  However, I have no idea how they have four tied for 17th place, a 19th and a 21st.  You can probably find out in the full report.


Hey, if you are a highly ranked energy efficiency individual, and if you still take showers, you might consider one of these LED shower-powered lights for your shower.  Does two things: saves lighting energy and water flow.  Good luck!  I came across this on the Sylvania website where I was visiting to vociferously complain about the expensive headlights on my car that simultaneously burned out after a measly 8 months surrounding summer use (very little).  This was the second pair (the other a different brand) of high output headlights that failed early.  Avoid them, especially if changing the head lamp is like threading a needle in a soda can – sharp edges and all.
