Why Energy Efficiency? – Five Findings

By Energy Rant No Comments
This year ACEEE published a three-part series on why people and companies invest in energy efficiency. First, they provide some guesstimates of energy efficiency investment in the United States. Their researched estimates vary from $60 billion to about $120 billion, annually. Is this a reasonable guesstimate? According to their State Scorecard, program spending on natural gas and electric demand-side management programs held steady at about $7.5 billion in 2016. Check. The International Energy Agency pegs worldwide investment at $231 billion and about $40 billion in the U.S. Check. As a laugh test, $100 billion is a measly 0.5% of the…

Energy Efficiency in a Land of Renewable Foie Gras

By Energy Rant No Comments
A couple weeks ago in Renewable Energy, Bad Parents, and Strawberries, I wrote that the value of an electrical generating resource depends a little on how cheaply it can produce energy (kWh), but a LOT on when and the (new word alert) dispatchability of the resource. For instance, California already has so much solar generation at the wrong time of day that it needs to dump kWh by paying producers to quit. This is demand response in reverse, or (new term alert) supply response. Yes, they are curtailing less than 1% of sales, but they are also two years ahead…

Renewable Energy, Bad Parents, and Midwest Strawberries

By Energy Rant 2 Comments
If you enjoyed the greatest modern decade of sports, when MJ went six for six in the NBA finals, you would remember this McDonald’s commercial nearby. In it, Larry challenges Michael to a game of trick shots for Michael’s Big Mac and Fries. (I don’t know why my adolescent idol, MJ, would agree to play for something he already paid for, but…) As you can see, the game quickly progresses into an outlandish game of “first to miss, loses.” It leaves off with a shot from the top of Chicago’s fourth tallest building, the Hancock Tower.

Reverse Diversification Coming to a Utility Near You

By Energy Rant One Comment
In my Personal Finance class as an undergraduate, our instructor used the term diworsification for large stalwart companies. Diworsification occurs when a company buys another company it knows nothing about and isn’t complimentary to the core business. Utilities got into this in the wild west days of 1990s deregulation, buying telecommunication and even real estate companies. That didn’t end well, and they went back to their core business of the regulated monopoly.In recent years we have experienced a reverse diversification of our power supply – namely in the reliable, conventional, thermal power plant sector. We still get almost half our…

Energy and Demand Resource Soup

By Energy Rant 2 Comments
The AESP 2017 National Conference is in the rear view mirror. While I was, unfortunately, not able to attend many sessions, most of that time was spent talking with a lot of people. I absorbed a lot of information and hopefully some wisdom. This post discusses the increasingly complex and intertwined electric grid. Shifting Role to Grid Managers My findings from the conference jive with a recent article I read in Public Utilities Fortnightly (PUF). The subject of that article was the Power of Innovation, a utility executive’s roundtable that included representatives from Edison International, Exelon, Duke Energy, Oncor, Southern…

Things You Need to Know Re Electric Vehicles

By Energy Rant 2 Comments
Last week I wrote about understanding the customer and knowing what they want, whether the customer is the utility, regulator, or the end user of energy. Taking this a step beyond, the customer/client may not know what they want. For example, a hypothetical customer may want to control all energy use in their house from a smartphone, 100% renewable energy, and a smart-grid connected electric car. I am convinced once the hoopla settles, customers will want (1) cheap, reliable energy, and (2) any help to be more successful. Three weeks ago, I wrote about Messing with Near Perfection. That post…

Distributed Energy Resources – Messing with Near Perfection

By Energy Rant One Comment
A couple years ago at an AESP conference, we had a fascinating speaker and topic. It was one of those that had me thinking deeply and philosophically. The subject was technology and the future. The takeaway: every problem is either a technical problem or one of human flaw. As for technical problems, there is nothing short of violating the laws of physics, including the second law of thermodynamics, that humans can’t and won’t someday solve: cancer, heart disease, failed or destroyed body parts, and of course, energy, and even aging. As we say at Michaels, (although we are not yet…

Residential Demand Charges; Harpooning Red Herring

By Energy Rant No Comments
On the one hand, this article from Utility Dive, The flaws in the utilities’ push for residential demand charges, had me shaking my head left and right in disagreement. On the other, not so much considering Solar City’s Chief Policy Officer co-authored the article. The article suggests that rather than using demand charges for residential customers, whether they generate renewable energy (solar) or not, utilities should use time-of-use rates instead. Time-of-use rates are a step in the right direction, but demand rates are still more equitable. Electricity Bills For new readers, here is a quick overview of various ways utilities…

Utility Scale vs Small Distributed Generation – Protection by Savage Suffolks

By Energy Rant No Comments
The June issue of Public Utilities Fortnightly (PUF) featured a supplemental, special report in collaboration with Navigant Research. One of the interesting articles in that publication is Impacts, Threats, Opportunities of renewable energy production. It compares utility scale to distributed renewable power generation. To refresh your memory, or perhaps for new subscribers, see my post on the Bogus Energy Internet of Things where I describe, in relatable terms, that distributed dinky power supply compared to the grid makes very little to no sense. The PUF/Navigant article backs this with the prices of wind and solar renewable energy generation for distributed…

Market Forces Give (Carbon Reduction); Market Forces and Flawed Policy Take Away

By Energy Rant No Comments
What is the purpose of the Clean Power Plan? To reduce emissions to 30% below 2005 levels by 2030? No. It has major flaws for actual, as in reducing tons of carbon dioxide release to the atmosphere, but I will come back to that later. As reported in Clean Power Plan Coma Phase, the country is already half way to the CPP goal, and it hasn’t even taken hold yet. Instead, it has begun the decades long legal battles with an initial vote of confidence handed down by the Supreme Court. How did we achieve 50% of the progress already?…
