Utility scale solar is built on the ground, no roof work required, very safe. The panels can be recycled almost entirely, similar to the utility scale battery storage that can back it. Tesla is scaling up utility storage manufacturing, Redwood Materials is scaling up recycling to close the loop and provide cheaper feedstock once there’s enough raw materials in the loop. Europe’s entire wind potential could power the world.

New nuclear is a pipe dream (~10-15 years from breaking ground to first kWh produced), but old nuclear generators should be ran as long as safely possible. Big fail on Germany’s part here, although natural gas price spikes will force their hand on more renewables, transmission (including cross border interconnectors), and battery storage.
