The only lasting way out of the fossil dependency is shifting electricity generation to renewables and nuclear. And electrifying the economy as rapidly as possible. We will present our electrification strategy before the summer. Electrifying Europe means making Europe more independent.

There's a certain category of commentator who wants to advocate for ignoring climate change who thinks "but what about the eventual heat death of the universe" is some kind of argumentative trump card and it's embarrassing every time. This is next level, though.

Back in DC for the week just in time for the most snow we've had in a decade. Since the National Guard is still here loitering around metro stations looking bored, seems to me the least they could do is get some shovels in hand and help dig out.

Going to be hard to provide real assurances while the administration is trying to illegally cancel hundreds of obligated contracts, literally rob a bank to claw back disbursed funds from the financial agent for the Greenhouse Gas Reduction Fund, and is defending those attempts in multiple courts.

National security concerns raised by the Pentagon during the leasing and planning of offshore wind projects south of New England were also fully mitigated, because that’s part of what the much maligned NEPA process does: Balances legitimate competing uses for America’s public lands and waters.

3 of the 5 wind farms just halted are in New England 🔍 There were "no major military issues that came to the fore in New England,” Bill White told me in August. He represented Mass. on a federally-led task force siting offshore wind farm areas. Here's the public record of the task force. 👇 🧵

10. In other words, in 2012 new production benefited domestic producers AND consumers. But today, new production only benefits producers. That's a fundamentally different policy and political environment. And note also that domestic consumption is basically flat for the last 20 yrs.

This is incredible (good news too): “After a 40% fall in 2024 in battery equipment costs, it’s clear we’re on track for another major fall in 2025…The economics for batteries are unrecognizable, & the industry is only just getting to grips with this new paradigm” www.pv-magazine.com/2025/12/12/b...

Batteries now cheap enough to make dispatchable solar economically feasible

Energy think tank Ember says utility-scale battery costs have fallen to $65/MWh outside China and the United States, enabling solar power to be delivered when needed.

In March, I was on an "Abundance" panel where I said that if Congressional Republicans repealed IRA credits for building clean energy at a time of skyrocketing demand, they were going to own the blame for rising energy bills. I think some people thought I was engaging in motivated reasoning. Welp!

We won’t have all the data for awhile yet but I’m predicting the 30C Alternative Fuel Refueling Credit is going to do way more to expand EV charging nationwide than any other program. (And could have done even more if not for arbitrary geographic restrictions imposed by Congress.)

It’s almost as though these competitively awarded grants in a highly oversubscribed program were selected on the basis of merit and need, not politics or ideology. But that was in the olden times of (checks watch) less than a year ago.

Before catastrophic floods swept through the Alaska Native village of Kipnuk on Sunday, the EPA canceled a $20 million grant intended to protect the community from extreme flooding. www.nytimes.com/2025/10/14/c...

Programmatic review provides a faster permitting process, so this change will result in unnecessary delays for bringing new generation online. In the Biden admin, responsibly expanding programmatic reviews was among many unsung reforms that brought federal permit times down by ~25% from 2022-2024.

🚗⚡ EVs win everywhere A new study shows that in every US county, electric vehicles now emit less greenhouse gas than petrol cars, no matter how you drive them. 🔗 pubs.acs.org/doi/10.1021/... #SciComm #EVs #ClimateAction 🧪

Greenhouse Gas Reductions Driven by Vehicle Electrification across Powertrains, Classes, Locations, and Use Patterns

We assess the cradle-to-grave greenhouse gas (GHG) emissions of current (2025) light-duty vehicles (LDV) across powertrains, vehicle classes, and locations. We create driver archetypes (commuters, occasional long-distance travelers, contractors), simulate different use patterns (drive cycles, utility factors, cargo loads) and characterize GHG emissions using an attributional approach. Driven by grid decarbonization and improved electric vehicle efficiency, we are first to report electric vehicles have lower GHG emissions than gasoline vehicles in every county across the contiguous United States. On average, a 300-mile range battery electric vehicle (BEV) has emissions which are 31–36% lower than a 50-mile range plug-in hybrid electric vehicle (PHEV), 63–65% lower than a hybrid electric vehicle (HEV), and 71–73% lower than an internal combustion engine vehicle (ICEV). Downsizing also reduces emissions, with a compact ICEV having 34% lower emissions than an ICEV pickup. We present the first evaluation of LDV emissions while hauling cargo, showing that carrying 2500 lbs. in a pickup increases BEV emissions by 13% (134 to 152 g CO2e/mile) compared to 22% (486 to 592 g CO2e/mile) for an ICEV. Emissions maps and vehicle powertrain/class matrices highlight the interplay between vehicle classes, powertrains, locations, and use patterns, and provide insights for consumers, manufacturers, and policymakers.

Their antipathy appears limited to the technologies that pose a near-term threat to an unnecessary gas expansion. Existing hydro has mostly already been uprated. SMR, conventional nuke, new hydro, marine kinetic energy sources will all take years to develop. Wind, solar, storage — not so much.

Justin Gerdes@justingerdes.bsky.social · 11mo ago

This announcement today from DOE affirms something that came up time and again at the POET/UMERC marine energy conference I attended last week. At least so far, Trump's antipathy for renewables has not been directed at hydropower and marine energy: www.energy.gov/eere/article... 🔌💡

Highlighting synchronous compensators is good; unfortunately Bloomberg is again repeating the fallacy that the precipitating event of the Spain blackout was solar failing. Thermal generators went down first, and then Spain’s grid regs (which can also be revised!) took solar offline as a precaution.

Bloomberg News@bloomberg.com · 12mo ago

The fix for solar power blackouts is already here — so why are so few countries investing in it? @akshatrathi.bsky.social‬ explains bloom.bg/3V9Ox2L

Earlier today, Bloomberg published what appears to be updated 'commence construction' guidance for wind and solar projects seeking to claim tax credits under the GOP megabill. BLUF: We should take no comfort that it "could have been worse" and there is very little to celebrate. 🧵:

Overturning the basis for America’s tailpipe emissions rules could actually raise prices at the pump — according to the Trump administration itself.

~17,000 Tribal homes in the U.S. still do not have electricity, including many in the Southwest. Off-grid solar and storage is by far the most cost-effective way to electrify these homes. Just needlessly, recklessly, pointlessly cruel to deny Tribal families access to power and refrigeration.

Sixth IRS commissioner in seven months unwilling to face jail time when directed to share confidential taxpayer data. Never thought I’d say this, but kudos to Billy Long. Political appointees violating federal law at other agencies should probably take a good look in the mirror.

Argument mostly resolved by this super interesting and depressing figure: doi.org/10.31223/X57... Clearly we're in a new normal. Open question - do we know yet whether the new normal is more like 2020/21 or more like 2023? I suspect the latter, since Canada is so darn big & it keeps burning. /end

Annual maps of smoke PM2.5 for the lower 48 over 2006-2023. Substantial increases over time in smoke across the US, but the increase is starkest in the Eastern half, and for 2023 the Eastern half is smokier than the Western half.
