Picture how big the Hoover Dam is. An absolute unit. The Hoover Dam has a power capacity of 2 gigawatts (GW).

The solar farm that the Admin just cancelled could have produces 6.2 GW of power. That's more than 3 Hoover Dams.

The thanks should go to the Resource Conservation District of San Diego!

We all need something tho because the news is bleak. And dumb.

Ok good news - We had a climate week in San Diego and at a home wildfire mitigation workshop we got 2 audience members (incl 1 HOA treasure) connected on launching a neighborhood fire safe council. So something very concrete came out, not just networking

Deleted OP because I had a glaring error - more renewable than coal electricity production, but neither are *half* of total electricity production

Lawrence Vulis @lvulis.bsky.social · 2h

It's hard to overstate how rapidly global energy dynamics and geopolitics are changing. More of the world's electricity was generated by renewables than by coal in the first half of the year.

And yeah this is essentially permanent (or 20 year, whatever lifetime of the Pv/wind install is) export of electricity production. Just a huge difference compared to oil and gas exports.

Lawrence Vulis @lvulis.bsky.social · 2h

It's in the recent ember report, also read the same. Googling and finding other mind boggling statistics.

"Solar PV exports in August 2025 alone totalled 46 GW, greater than Australia’s entire solar capacity, setting a new record in GW terms."

ember-energy.org/latest-updat...

China's clean technology exports hit record high in August, reaching $20bn | Ember

Analysis by energy think tank Ember shows that adopting a 45% renewable energy target rather than 40% would slash EU gas imports in half and save billions in gas costs in 2030.

District heating is one of the solutions for low-emission heating in cities. It's not easy due to high upfront, non-socialized investments and the complicated agreements needed.
But in Delft, a project for 6,000 homes is under construction, with geothermal heat!

Renewable energy overtook coal as the world's leading source of electricity in the first half of this year - a historic first, according to new data from the global energy think tank Ember.
