Use Solar/Wind and convert it to green hydrogen or green ammonia. We've reached the limits of pumped hydro and batteries are not dirt cheap yet. Green hydrogen and ammonia solve multiple problems. Both are fossil fuel products now.

Hydrogen is corrosive and explosive, next to impossible to store/transport safely. Green Hydrogen for immediate consumption at industries that require high heat and electricity is not an option.

Green ammonia for fertilizer and as energy storage.

With abundant oversupply of solar, we can start building alternatives to all fossil fuels.
