A lovely good news story -- a community solar project on a former Superfund site in Illinois provides big savings to the school district and community members: vist.ly/4p7kc h/t Kari Lydersen for @canarymedia.com
How community solar turned a Superfund site into savings in Illinois
A new 9.1-MW solar array will help residents of Waukegan, Illinois, reduce energy bills. State incentives for low-income solar made the project possible.

Here's a commercial-scale thermal battery (hot rocks!) that is providing heat at 1800C, which is what you need for processes like steel & aluminum.
Industrial heat was one of those "difficult to decarbonize" sectors until, y'know, we tried.

US states should pass policy that clarifies this issue before it comes to a head. Otherwise gas utilities and their major investors will lobby to make people pay exit fees when they get off gas, potentially killing the economics of electrification.
