Unpopular clean energy opinion: reducing air pollution, which kills millions, is more urgent and important than fighting climate change. Both important of course. Fortunately both problems can be mostly solved by the same tools too, so there's no question of "what should we do?"

I recently saw a pitch deck talking about the great opportunity to take advantage of high ancillary services prices in CAISO. PSA for the industry: that opportunity already expired. It was always a thin market (a few 100 MW) and the new batteries killed it last year. It's over.
