It’s possible to make things better! (A hopeful reminder that I need frequently.)

An energy revolution is underway in this century, though it’s unfolded in ways slow enough and technical enough for most people not to notice (and I assume it’s nowhere near finished). It is astonishing – a powerful solution to the climate crisis... [Wrote it a while ago; came out yesterday.]

the one thing i genuinely did not anticipate from this administration was its vicious, know nothing hostility to any and everything that might even be adjacent to science and scientific research. they genuinely one to destroy the entirety of the nation’s research capacity. and for what, exactly?

This is twice as money much as the Department of Energy spends on solar power R&D. We could have more solar power but instead we’re paying to build detention camps.

The rest of the world will learn an important lesson from China. Build out your renewables so you aren't as dependent on imported fossil fuels and the whims of idiots. "China’s imports of three major energy products from the US hit almost zero in June"

🇨🇳 China installed 464 GW of solar capacity in the 12 months to June☀️ That's more than the total EU solar capacity as of 2024 (338 GW) and DOUBLE the total US solar capacity (229 GW). ...in just 12 months

The thing that stands out here is so many Dems run campaigns terrified of (and thus buying into) the Fox News framing. Mamdani is rightly mocking that framing as ridiculous and it resonates. He's not running scared. He's running proud of who he is and what he stands for.

Paris urban biking DOUBLED in just one year. “Cycling in Paris has transcended mere trendiness; it’s become a fundamental aspect of the city’s identity. Despite challenges like inclement weather, cyclists continue to flock to the streets, setting new records and reshaping the urban landscape.”

“Vaulted Deep operates like a reverse oil company.” More of this, please 🙌🏻 techcrunch.com/2025/07/17/m...

I've been saying to friends for a few months that the more I study authoritarianism in other countries, the more concerned I become that the CBS story is the sleeping giant here. The process has been a simmer (people inside the network have spoken out in real-time) but don't mistake slow for safe.

oh

"As temperatures across New England soared above 100℉ in recent weeks, solar panels and batteries helped keep air conditioners running while reducing fossil-fuel generation and likely saving consumers more than $20 million." www.canarymedia.com/articles/cle...

This post doing numbers is itself a perfect illustration of why example-setting by celebrities is a massive deal when it comes to mainstreaming climate. Visibility is the name of the game!

We should be putting a gargantuan amount of money into solar and storage. War economy levels. It should be free to have a guy from the government solar your house up. Electricity should basically cost nothing.

moood. but yet we persist

Down with AI, up with AC

Maybe this is just rage bait at this point, but I find it Interesting that heating uses 4x the energy globally as cooling does, but authors of AC-shaming articles like this never call for people to just “tough it out” through the winter without heating their homes 🤔

An example of why when ppl ask me how I feel about about our climate future I say that despite despair over the climate impacts we are already seeing I am more optimistic than I’ve ever been that we are making progress.

Transit ridership in major French urban areas is now substantially higher than it was in 2015—while in the US, it's still way down. No major US urban area has higher per-capita ridership than it had a decade ago. On this metric, the US is headed in the wrong direction. www.urban.org/urban-wire/t...

🌡️ June 2025 was the 3rd warmest June globally 🥵 June 2025 saw an exceptional #heatwave impact large parts of western Europe 🌊 This heatwave was made more intense by record ocean temperatures. #climate change means heatwaves are: 🌞more frequent, 📈 more intense & 🌍 impact more people 🧪⚒️

I make the case for local permitting reform to make distributed solar cheap in New Jersey. The same argument applies everywhere. Cut the insane red tape that is a big reason why rooftop solar costs 2-4x as much in the US as it does in other peer countries. www.njspotlightnews.org/2025/07/op-e... 🔌💡

Developing nations leapfrogging the fossil fuel stage. We're seeing this in Pakistan with rooftop solar, in Ethiopia and Nepal with electric vehicles. Hugely important for all of us.

Zohran has become a sensation simply by virtue of being a palpably nice person who cares about his community, wants to make their lives a little easier, and thinks the rich could contribute a little more to help with that. The far right and hard centre have absolutely no good answer to this.

New: Trump has issued a new executive order targeting the solar and wind industries, instructing the Treasury Department to limit how many renewable energy projects can still claim clean electricity credits under OBBA www.whitehouse.gov/presidential...

punishing the industries that are building out new electricity generation quickly while simultaneously warning of future blackouts is contradictory behavior. full stop. i wish i had even one small silver lining to point to

One of my first exchanges on this website was someone telling me that batteries were far too expensive to be part of the solution when paired with solar. I told them I didn't think they understood what was happening. That was around Sept 2023. People still don't get it. They will soon.

Battery storage just hit a watershed moment: $51/kWh in China, down 30% in 12 months. While fossil fuels get slower & pricier, batteries are getting cheaper and better. This isn’t a trend—it’s now a rupture. Solar + storage is now the default for new energy. Everywhere. ⚡📉 #BESS #EnergyTransition

"The bottom line is that Trump and DOGE made drastic cuts to the NWS and the NOAA. Retired federal scientists warned the cuts could hamstring forecasts and make extreme weather events less predictable and more dangerous."

In a sane world, this would be the biggest, most important news story in the world. ‘Tipping points’ experts issue urgent message to world leaders. “Every fraction of a degree above 1.5°C matters. And every year of “overshoot” matters too.” “It’s ultimately a matter of survival.” #ClimateCrisis

I know we don't feel like there's much to celebrate this July 4th. It's been a rough several years. So I want to talk about how we're making history right now.

Freedom from kings. Freedom from fascism. Power to the people forever. ♥️ Happy Independence Day 🇺🇸

America is beautiful, contradictory, unfinished. I am proud of our country even as we constantly strive to make it better, to protect and deepen our democracy, to fulfill its promise for each and every person who calls it home. Happy Independence Day. No Kings in America.

Trump's "Big, Beautiful Bill" has passed. The consensus is clear: this will be bad for the climate, environment, and clean energy. Check out a round-up of partner coverage on the topic 🧵

A little good news! The New Jersey Legislature just unanimously passed S4100, which would allow families statewide to get permits nearly instantly for rooftop solar and home battery projects using an online, automated platform administered by the state. Governor Murphy should sign it.

What does the One Big "Beautiful" Bill mean for the US energy transition, household and business energy costs, electricity supplies and emissions? We've published a quick summary report of our findings here: doi.org/10.5281/zeno... #OBBB 🔌💡

• Mamdani is not in the country illegally • He does not have any connection to 9/11 or jihadist terrorism • Mamdani hasn’t actually said or done anything antisemitic • He did not call to ‘globalize the intifada’ • He’s not a communist

I think it’s really important, when considering what we’re investing in for the future of decarbonization, to consider that techs depending on cooling water might simply be seasonally unviable under future climate conditions

In October 2024, multiple top-tier media outlets told me their editors wouldn't approve stories on our Project 2025 modeling because Trump disavowed the plan. And here we are. heated.world/p/this-is-ex...

There is race underway to electrify the world. US lawmakers are voting on bill this week that will choose whether the US stays in the race or withdraws. My newsletter this week: www.bloomberg.com/news/article...

renewables tax is out of the senate bill now

It's not hyperbole to say that Pakistan is on track to leapfrog traditional power grids and jump straight to loosely-connected (and when needed, off-grid) distributed solar + battery systems. It's like developing countries leapfrogging land-lines and moving straight to cell phones. It's incredible.

They want to close the NOAA lab (GML) that brings you this, the most iconic time series in the environmental sciences. gml.noaa.gov/ccgg/trends/

My senator! Thank you @warnock.senate.gov 🙏🏻

Wind and solar are not fringe technologies in the US. They have overtaken coal in 24 states since US coal generation peaked in 2007. This includes red states such as South Dakota, Oklahoma, Kansas and Texas... ...and, as of 2024, the US as a whole!
