This Week in Cleantech

Grist

Paul Gerke and Mike Casey cover how old batteries, solar panels, wind blades and grid gear are becoming a new source of critical minerals, and how Britain plans to balance a fast-growing grid. They dig into Zeke Hausfather’s analysis showing wind and solar avoided 3.7 billion tons of carbon pollution in 2025, and why tandem solar panels could help the US catch China. Grist’s Benton Graham explains the battery-powered commuter trains coming to Boston, Chicago and the Bay Area. Cleantecher of the Week is chef Christopher Galarza, whose study found unsafe NO2 levels in gas-fired kitchens.
