The government’s own data rebuts Trump Admin claims that wind and solar are driving up electricity prices, Politico reports share.google/RTIXPPQMXrTH...
“[T]he data say pretty much the opposite” of Trump & Secretary Wright’s claims.

Among the 22 states that drew higher-than-average shares of their power from wind and solar, 17 had below-average electricity prices in June, according to EIA data.

Solar leads EU electricity generation as renewables hit 54% share.google/WEiX2aSdEwj9... 🔌💡 ☀️

According to new data from Eurostat, renewable energy sources generated 54% of the EU’s net electricity in Q2 2025, up from 52.7% year-over-year. The growth came mainly from solar, which produced 122,317 gigawatt-hours (GWh) – nearly 20% of the total electricity generation mix.

June 2025 was a milestone month: Solar became the EU’s single largest electricity source for the first time ever. It supplied 22% of all power that month, edging out nuclear (21.6%), wind (15.8%), hydro (14.1%), and natural gas (13.8%).

In the Post (& elsewhere), Energy Secretary Wright continues to get basic facts wrong. He claims “We’ve been talking about ‘electrify everything’ for a while. Today, 15 percent of energy in manufacturing comes from electricity, same as it was 25 years ago.” False. Here's the real global data.

Well 🤬

If global temperatures continue rising, virtually all the corals in the Atlantic Ocean will stop growing and could succumb to erosion by the end of the century, a new study finds.

The analysis of over 400 existing coral reefs across the Atlantic Ocean estimates that more than 70 percent of the region’s reefs will begin dying by 2040 even under optimistic climate warming scenarios.

And if the planet exceeds 2 degrees Celsius of warming above preindustrial temperatures by the end of the century, 99 percent of corals in the region would meet this fate. Today, the planet has warmed about 1.3 degrees Celsius over preindustrial temperatures.

The implications are grave.

What if charging EVs is really cleaner than we think? Read our new open access paper below to find out why! 🔌🚗 🔌💡

Emil Dimanchev @emildimanchev.bsky.social · 21d

Excited to share a new paper I got to help out with!

How much emissions do EVs cause through the electricity they consume? How do we know?

Our paper shows that frequently used metrics *over*-estimate EV emissions.

We’ve had geothermal on two residences over the past 15 years and it was a non-negotiable feature for each home. Our HvAC operating costs have been as much as $10k/yr less than our neighbors.
Lowering the cost and complexity of installation would be a massive game changer. This is very exciting!

As soon as I heard about Dig Energy's unique approach to slashing the cost of drilling boreholes for geothermal heating and cooling by 80% or more, I knew: "if this works, this will eventually just be how we heat every building, everywhere." techcrunch.com/2025/09/09/g...

Dig Energy's water-jet drilling right promises to cut drilling costs by up to 80%, helping geothermal heating hit price parity with fossil fuel furnaces.
