Demand Management for Good

By Energy Rant No Comments
The last few posts featured an overview and complete report card on load management to get beyond net zero to real zero, a term I discovered last week. As promised, I will describe some permanent peak load reduction opportunities this week. Like many efficiency solutions, blocking and tackling approaches are the most effective. Peak Load Reduction – New Construction I’m going to stick with some big hitters. A person could write forever on this topic. Home Envelope Single-family homes must be super-insulated to minimize heating loads in cool/cold climates. The cartoon below provides a nice example of super-insulated versus code…

Better than Best Programs with Market Transformation

By Energy Rant No Comments
Last week I couldn’t resist responding to the ISO New England’s report, 2021 Economic Study: Future Grid Reliability Study Phase 1 because it paralleled what I wrote a couple of weeks earlier in Electrification At Scale. This week, we’re back to better than best practices in efficiency programs. Last time I described how downstream rebates are often wealth transfers because they are downstream of key decision points and barriers. As I replied to a job candidate who asked me how I would approach a utility to try to persuade them of this, I described how our purpose for being in…

The Non-Energy Benefits of COVID, and Energy

By Energy Rant No Comments
Way back in April, I had generated a list of non-energy benefits of the COVID. One was the lack of traffic. That made driving easier and running a little safer with less hassle. Second, my, uh, wellness trainer stopped making trips to Europe, so rather than being gone a week a month, he’s never gone. As a result, my Feng and Shui have been in balance. Third, my car insurance company has credited my account a few times because they think I’m driving less – which reminds me of the fourth: gasoline prices are lower than ever, inflation-adjusted. Fifth, I’ve…

The End of Lighting

By Energy Efficiency, Energy Rant 4 Comments
Believe it or not, I did not have a rant topic in mind going into Saturday morning – my rant writing time.  But the fog burned off quickly as a topic came into view – one that arose during the prior week.  Incidentally, I once heard a “meteorologist” instructor say he always scolded his students for saying fog “burns” off.  Instead, they should say the fog lifted.  What?  Fog is suspended water droplets, not vapor.  Water vapor in air, or as steam, is invisible.  When fog “burns off,” it changes from visible water droplets to invisible vapor, so while “burn…

Need Not Miracles

By Energy Efficiency, Energy Rant, Renewable Energy, Sustainability No Comments
Thousands, make that millions of people, including some smart people and congress people, when talking solutions for our energy efficiency low-carbon future are continuously babbling about “technology” that will save us all.  Bill Gates says we need Miracles.  Whadahyou talking about man?  The White House announces $130 million for a new building energy efficiency effort - “a multi-agency initiative to spur regional economic growth while making buildings more energy efficient.”  It will be “an Energy Innovation Hub focused on developing new technologies to improve the design of energy-efficient building systems”.  Get ready for cold fusion to reemerge. Let me tell…
