Compressed air energy storage has been used for decades, but only at two facilities in Germany and Alabama, built before solar and wind started creating challenges for power grid operators.

“This is a pretty simple concept,” said Bobby Bailie, director of business development for energy storage at the German industrial firm Siemens. “You’re pushing air into a cavern, storing that energy. And at times when you need it, you pull it back out.” — The Los Angeles Times

The group of neighbors has explored the ways it could fight to get the paint job removed, including how it could be seen as graffiti under city code, how it could violate signage laws and how it fails to fit in with the character of the neighborhood.

Proposition 105, a measure backed by a group called Building a Better Phoenix, would halt all future light rail expansions, directing already-earmarked tax dollars toward “other transportation improvements”—mostly road construction. Like a number of efforts to kill urban-rail plans around the U.S., the initiative to stop Phoenix’s transit development has ties to Americans for Prosperity, the advocacy group funded by David H. Koch and Charles Koch. — CityLab

The Autorité Environnementale (AE) has issued a statement saying a future scenarios study by the airport had underestimated the project’s environmental impact and overestimated its economic benefits. The new Terminal 1 extension is scheduled to open at the start of 2023 [...] However, it appears those plans clash with France’s new target to be carbon neutral by 2050, prompting the environmental agency to demand clarification. — Architects Journal UK
