Less and less solar as the year winds down, but still 100% WindWaterSolar for part of the 218th day this year (67% of all days)

53% of all '25 demand supplied by in-state WWS (v 49.7% in '24 & 45.7% in '23)

Gas down 16% v '24 & 37% v '23
Demand down 2.1% v '24 & 1.4% v '23 due to growth of roof PV

As @mzjacobson.bsky.social says, there are no miracles needed. We have almost all the tech required to address human-caused climate change. But @doctorvive.bsky.social is right. We need the courage to deploy those technologies as rapidly as possible. 🧪🔌💡☀️💨💧🔋 www.iea.org/reports/worl...
