Climate change communicator. Focus on what scientist and economist wonks tell us, and the controversies, because everyone opposes at least one major solution.

    Curtailed solar + wind. Will update when CAISO separates solar, wind; guessing solar, wind generation for Nov, Dec. Wind at low capacity factor many days since Oct 31, 1/3 of Jan (10% cf = 16.1 GWh). Hydro, small hydro both below last year. So why so much solar curtailed?

    A great piece unpacks the critical lesson behind the apparent riddle: Why can adding more "cheap" wind & solar may be more costly than adding an "expensive" clean firm resource like geothermal?

    Final vote: FAILS. But Wiener can bring it back tomorrow if he whips 3 votes over night.

    THIS!! Super important step. this will help evaluate a critical path to decarbonizing worldwide shipping. Low-C hydrogen, blue & green, will make this possible. ⁦⁩ to run ship fitted with ammonia fuel cells

    Donald Trump must be convicted and removed from office. Because he will always choose his own personal interest over our national interest. Because in America, right matters. Truth matters. If not, no Constitution can protect us. If not, we are lost.

    Here is a blunt reality: if Chief Justice Roberts is saying nothing about Republicans violating the rules openly and leaving the chamber during these presentations he is violating his own role and oath and should be roundly condemned.
