Amazing chart. Energy *importers* have invested about 5x as much in renewables and nuclear as in fossil fuels since 2022. Energy *exporters* have invested about twice as much in fossil fuels as in renewables and nuclear.

Fantastic graphic...
The world's energy importers are investing at MASSIVE scale into cleantech.
No one wants to be dependent on imported fossil fuels.

i don’t think people realize how insane the produced water situation has become out in the permian
New: Oil companies, running out of space to store brine that bursts free with other fossil fuels, are using AI to scour the surrounding geology — hoping they can get to suitable underground formations faster than the competition as production skyrockets texastribune.org/2026/05/21/…

btw, regulators confirmed to us this morning that the 19 new turbines (and the 27 already on site) are not part of an air permit granted in March, meaning xAI has more than 1 GW of unpermitted gas power at Colossus 2 right now
May 13
NEW: xAI appears to have added more than 500 MW (!) of unpermitted gas turbines to its Colossus 2 campus in a matter of weeks, according to internal emails between the company and regulators

My goodness there is a lot of happy talk about data centers *lowering* customers' rates. It hearkens back to gentler times when there was still juice to squeeze and the glass wasn't full.

Huge. A Brookfield-backed datacenter company is pulling out of a major project in Virginia, that they had been working on for years, due to growing political opposition bloomberg.com/news/articles/…

We can't afford to pour tax dollars down the drain like this: "The irony is that the interim state route [37] project, slated to cost over $500 million, will be underwater within two decades of completion, due to sea-level rise it helped cause."

Don’t forget, this didn’t just happen. Mandates work!

This was shocking to me. Lighting has gone from the largest residential use of electricity to the sixth-largest in my lifetime. Clothes dryers alone now use more aggregate electricity than lighting in people's homes.

This is actually ridiculous.

Solar was 3/4 of global growth in electricity last year. Wind was 1/4.
China was the majority of growth in solar, in wind, and in total.
Coal was down in China and globally, up in the U.S.

New research released for #EarthDayEveryDay finds that despite the rapid growth of renewable energy usage, the even-more-explosive growth of data centers is delaying the transition to a cleaner grid in ways that could harm the air we breathe. environmentamerica.org/cente…

We've been banging the drum about data center-driven delays in coal plant retirements since early 2025. And here are two more. On Earth Day, no less. abc27.com/pennsylvania/penns…

Coincidentally, today we're releasing two briefs tracking the slowdown in fossil fuel plant retirements and the implications for our air. The first finds that ~ 1/3 of the coal-fired capacity that had been slated to go offline by the end of 2025 hasn't. frontiergroup.org/resources/…

The second tracks air pollution emissions from units at 15 power plants whose retirement dates have been delayed, finding that in 2023, those units produced >25,000 tons of sulfur dioxide, 27,500 tons of nitrogen oxides and >250 pounds of mercury. bsky.app/profile/frontierton…

There's a big impact of small #SolarPower because it can deploy fast and everywhere.

US small-scale solar hits record 1.9 GW in Q4 2025: Distributed solar accounted for 15% of all new US power capacity in 2025, as residential and community projects reached record installation levels. dlvr.it/TRpdsG #Photovoltaics #EnergyStorage #RenewableEnergy

Big TY @azcentral for publishing op-ed by @ArizonaPIRG Education Fund's executive director. "If you are a consumer who has an electric, gas and water utility regulated by the commission, this means you could be faced with a triple blow to your budget annually for five years...".

Opinion: Approved formula-based utility rates could mean higher bills for consumers more often than in the past, benefitting the companies, not you. azcentral.com/story/opinion/…
