Some folks pin excessive weight on the federal government’s influence over our efficiency and load management industries. Even though billions/trillions of dollars are allocated through the “Inflation Reduction Act” and “Bipartisan Infrastructure Law,” those funds are fleeting. What’s more enduring? Rising electricity prices and load-balancing authorities are pushing for more baseload generation and transmission-line construction – things that are always met with stiff resistance by state and local governments and stakeholder groups. Utility Dive recently reported that electricity prices outpaced the broader U.S. consumer price index. Well, gee, why would this happen? Have fuel prices increased? No. You’d think electricity prices…

This week's Energy Rant is written by Kenny Porter and Tyler Kashdan of Michaels Energy. As I shoveled my way out of the recent record-breaking snowstorm, I couldn't help but reflect on the monumental effort it took to move all that snow. It reminded me of our work in outreach. Not the physical lifting of snow, but the weighty task of convincing customers that their time isn't wasted and that real benefits await them by enrolling in utility energy efficiency programs. We're dedicating this blog to talk about our role as Account Managers. So Much Waste Did you know that commercial…

Energy efficiency program administrators can be quite conservative regarding change and innovation. I love hearing, “Bring us new ideas that have been successful in three or four other programs.” There you are! The pinch is on. Energy efficiency codes and standards have raised the bar consistently such that incremental savings from one code change to the next are exceedingly scarce. The gravy-train days of incremental widget-efficiency improvements, including lighting efficacy and heating and cooling equipment efficiencies, are quickly closing. Vehicles A nice parallel to diminishing returns on efficiency is vehicle mileage. The following chart shows fuel energy consumed per thousand…

For years, I wondered how the national debt would result in Great Depression-level pain and a reset not unlike bankruptcy. The national debt doesn't need to be paid back like we often hear or read in the news. It just needs to be maintained at manageable levels, defined as not letting the borrowing cost get to a prompt supercritical situation that overwhelms everything else. Financing costs are becoming alarmingly high – already more than we spend on national defense – about $1 trillion annually. When tax revenues to finance the debt are insufficient, or if debt markets bomb, the Federal Reserve steps…

Two weeks ago, I described an array of district heating and cooling plants that serve medical, college, industrial, and even city-scale loads. Last week, I explained options to decarbonize district heating and cooling plants. Those options include converting systems from steam to hot water as equipment reaches the end of its useful life, heat recovery chillers, and, most importantly, energy efficiency in facilities and processes served. But before getting started on efficiency, I must add that there are also many barriers to shutting down a district steam plant and transitioning to distributed heating and cooling plants. First, there are loads other than space…

Let's begin with Oxford Dictionary's definition of decarbonization. Noun: reduction or elimination of carbon dioxide emissions from a process such as manufacturing or the production of energy. Last week, I introduced central or district plants that serve multiple buildings with steam, chilled water, and, in many cases, electricity. District plants serve colleges, healthcare, manufacturing campuses, and, in some cases, entire sections of cities. This week, I describe issues and strategies to save energy and decarbonize these plants. As I learned early in my energy efficiency career, it is essential to understand the design logic behind the system before recommending modifications. Steam moves…

I would like to see a poll of peoples’ suggestions for decarbonization. My guess is solar panels would be near the top; next, maybe an electric vehicle; after that, maybe electrified appliances and HVAC. Are any of these investments cost-effective? Keeping it simple, are the accrued savings over the life of the project or object more than the cost? It depends on the baseline alternative and various stackable incentives. Without guessing and getting into details, I believe consumer electrification and decarbonization are driven more by non-financial matters. What about commercial and industrial facilities? It gets decidedly more challenging because the…

I took advantage of the cold weather this week to demonstrate ice formation again. Caution: video ahead. When I take to Google and ask, "What is the freezing point of water?" it apparently depends on my location 🙄. You probably know that the boiling point of water changes with barometric pressure, but the freezing point also changes with pressure – but over a much greater range of pressure, as shown below. A change in the melting point of ice of two degrees Fahrenheit requires 2000 pounds per square inch (psi). The range of atmospheric pressure everywhere on the planet only varies…

My top "strength," according to Gallup's CliftonStrengths survey, is context, which means knowing and understanding history to assess situations and inform and guide decisions. "Those with Context are the people in our lives who instinctively look to the past to understand the present." How does this affect my perspectives? Historical context serves as an impenetrable bullshit filter. I.e., we've been here before. I recognize this pattern, and I'm not joining the mob. See you later. We're Going to Starve If you're over 50, you were probably told that we would run out of food. Here are some zingers from the 1970s. "Population will…

The depth of decarbonization will ride the line where the net of cost and convenience meets that of conventional alternatives. Polling from the University of Chicago indicates 38% of Americans are willing to chip in one (1) dollar per month to fight climate change, down fourteen percentage points from 2021 (presumably, that 14% are willing to pay nothing now). Or, as one Wall Street Journal article noted in November, “Someone has to pay for it, and shareholders and consumers decided this year it wouldn’t be them.” For instance, I like to cut, split, stack, haul, and burn wood for heat. It must burn hot…
