An interested layperson foolishly tackling the incumbency most entrenched in just about every aspect of our lives: alternating current electricity in buildings.

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientistβ€”because the person felt she did didn’t deserve the recognition.

If New England's full 3.5GW fleet of offshore wind had been operational last winter (instead of being attacked by the Trump admin), the region's blackout risk would have been cut by 75% and consumers could have saved *over $400 million*. πŸ”ŒπŸ’‘

Senate Dems should heed this warning. Yes, we care about affordability. But that is not the primary concern when Americans are being gunned down in the streets.

Nice piece on the struggle of directing people's attention to the horizon - climate change - when fascism is staring at you in the face.

When it all gets too much for me, I get busy trying to get rid of fossil fuels (in my own life, in society around me).

NY wind project resumes | China grid investment to β€˜surge’ | Global elite β€˜concerns’ - Carbon Brief A New York offshore wind project is to resume construction after a federal judge temporarily lifted a suspension put in place by the Trump administration

State Grid, China’s main grid operator, will invest 4tn yuan ($574bn) to upgrade the country’s power grid over 2026-30, an average of 800bn yuan in investment per year, reports Reuters. πŸ”ŒπŸ’‘

Do one doubts that you can make a firm dominant grid work.
They have enough hydro and biomass capacity to cover their firm demand, but not enough water to cover their annual GWh.
This is a great use of VRE as a resevoir extender, but doesn't scale / extend unless you have the hydro resource. πŸ”ŒπŸ’‘

Batteries are the fossil fuel killer.

China knows and would prefer to not be reliant on fossil fuels from place like Venezuela. So they do this.

US Electric Grid Heading Toward 'Crisis' Thanks to AI Data Centers | Common Dreams The massive energy needs of AI data centers spark political controversy in 2026. Concerns rise over impact on grids, environment, and utility bills.

Rob Gramlich, president of power consulting firm Grid Strategies, told CNBC that he expects the debate over data centers to become even more intense this year once Americans start getting socked with even higher utility bills. πŸ”ŒπŸ’‘ @robgramlichdc.bsky.social

Any discussion of how a few actors are protesting Trump's takeover of the Kennedy Center has to consider how Republicans have tried to slash social spending for the arts β€”Β and denigrate the arts and humanities as legitimate fields β€”Β since at least Reagan, if not longer.

It’s the β€œseason of love and giving”…but this year, doesn’t it seem more like a β€œseason of fear and taking”? Like many of you, I’ve been saddened by the human impact of draconian government budget cuts and how angry many housed Americans are at unhoused Americans.
