Insane new research. Scientists gave asthma patients free electric stoves to replace their gas stoves, then checked to see if symptoms improved. Not only did symptoms improve, ditching gas was *better than medicine.* Details in today's newsletter: www.climatecoloredgoggles.com/p/electric-s...

Researchers used electric stoves to treat asthma. It worked.

Great coverage of our working paper. 2 things I wish made it in the story: 1. Strong reasons to think that scaling up the grid reduces prices long run—excellent news for electrification. 2. The big risk with data centers is uncertainty—what if they don’t stick around to pay for all the new stuff.

To estimate whether data centers raise electricity bills, you need to solve a classic econometric problem: data centers pick low-price locations, which makes them look good. Our solution involves Dwight Eisenhower. New working paper with @asawatten.bsky.social and Geoff Blanford 🧵

It is shocking (intended) to think what's going on here is that the world has other options besides oil, unlike in 1973. And that's why the price shock is 1/3 while the supply shock is 3x. Looking forward to your papers in 2029 :p

Average residential electricity rates compared to inflation. While prices for goods are surely downstream of energy costs, it is notable that inflation spiked first and rates followed. Gray are individual states, black is US average, blue is CPI.

Some version of this point has been made for at least 20 years. And I guess economists still need to make it! The biofuel/renewables hokey pokey.
Fact 1: both renewable diesel and SAF are $2-$5 per gallon more expensive to produce than their fossil counterparts. Therefore, they need substantial subsidies to be cost competitive, otherwise they will not be produced.

Fact 2: the federal renewable fuel standard (RFS) requires that a minimum quantity of biomass-based diesel fuels be used in the United States each year. SAF counts as biomass-based diesel in the RFS. If the industry produces more biomass-based diesel than required, then the RFS subsidies will disappear. It has no incentive to go above the mandate because of the first fact. Therefore, more SAF means less renewable diesel in aggregate.

Final EIA-860 is out, and 2025 really did it: 54 GW of new U.S. electric capacity, 96% clean. Solar again carries the offense, and we built more storage in 2025 than the cumulative total through 2023. More and more and more additions... but also record low retirements.

BTC is a computation treadmill. Jensen's paradox (⬆️efficiency=>⬆️demand) is weak for many things (cars, lights) bc demand is inelastic. Not so for crypto mining! Makes sense. Miners mine until marginal cost=marginal benefit. ⬆️eff=>⬇️mc=>⬆️mining=>⬇️mb. An EPRI brief: www.epri.com/research/pro...

It's important to cover all the bases
Google Gemini answers: No, if confidence intervals overlap, the difference between the two estimates is not statistically significant. However, it's possible for the difference to be statistically significant even if the confidence intervals overlap.
