Recent projects have led me to examine how deregulated electricity markets work. Since I am naturally curious, I wanted to investigate differences between electricity price performance of deregulated states versus those of regulated states. This week we examine the impacts of regulation/deregulation on pricing, and next week, we will look at the impacts that renewableRead more

Energy storage is easy and cheap. Grid-grade electricity storage is complex and expensive. Definitions of energy storage vary. Some consider hot water, chilled water, or ice to be stored energy. It’s really storing the benefits of energy consumption. For phenomenal refreshers and mental strolls down memory lane, see Storing Energy v Storing Benefits and SomethingRead more

“Don’t drink the Kool-Aid” and being as objective as possible are how I roll. If you feel otherwise, by all means, let me know. Driving across Southern Minnesota recently, a billboard like the image nearby caught my eye. I thought this would be worth looking into to see what they have to say. As IRead more

I spent last week at the Association of Energy Services Professionals (AESP) National Conference in New Orleans. Our industry is in transition once again. Substantial changes are on the horizon. Let’s recap some highlights and lowlights in the utility and demand side management industries the past few decades. As nuclear power was going to beRead more

This post features concepts everyone can use to identify terrific savings opportunities, even if you did not take beloved calculus and thermodynamics. Let’s review a general hierarchy of typical energy efficiency families: 1. Shut it off 2. Slow it down, set it back (temperature, etc.) 3. Reduce waste 4. Retrofit or replace with efficient equipmentRead more

Exergy is a sexy word (maybe only to energy nerds), but it represents a vital class of measures and opportunities as we sprint head-on into the game changer (cliché alert) that will be the post-gravy-train-of-lighting-retrofit-era of energy efficiency. Pay attention! Exergy, also known as availability, is the total useful energy that can be captured beforeRead more

Upon reading some manager/principal/owner interviews in business publications, the publisher asks, “What keeps you awake at night?”  My answer to that would be: Nothing.  The reason for this is utilities are regulated monopolies and the energy efficiency program portfolios they run are cost effective.  I.e., we, as an industry, are contributing to net wealth generationRead more

In Stalin Lives, I mentioned our plan for securing an ENERGY STAR® clothes washer and dryer for our house.  What I did not mention was that the local appliance stores do not even stock gas-heated dryers. Think about how stupid it is to generate electricity with maybe 35% thermal efficiency, lose 10% of it toRead more

This will blow your mind.  How many large power plants (500 MW) does it take to cook the thanksgiving turkey across the nation – just the ones cooked with electricity?  Answer is provided below.  Guess.  Don’t be a loser.  Guess. I’ve seen perhaps 100 ads for dust collecting contraptions that everyone including the buyers knowRead more

In 1984 was not like 1984, I talked about greeting change with gusto to win the future but with few specifics.  This post will cover one such “innovative” way for all stakeholders to benefit from energy efficiency. The typical utility-sponsored energy efficiency portfolio works like this: A small percentage of billed energy consumption, aka aRead more

This week features an overload of potential topics but let’s start with this one: Can we put some adults in charge in certain seats of power in Washington.  I’ve mentioned in previous posts, the EPA is running wild when it comes to mandating emissions requirements from power plants.  Lisa Jackson, head of the EPA andRead more

As administrations and congresses come and go, one thing remains the same: “there is no clear energy policy”, and “we need to reduce our dependence on foreign oil”.  Neither one is ever addressed. First, what the heck is a clear energy policy anyway and are we sure we want one?  When the government messes withRead more
