The IEA says renewable electricity from wind and solar are on pace to manufacture enough hardware to generate enough electricity to meet all electricity needs - the report also suggests that all energy needs can be met in time. Including industrial and transportation.

This is being done aggressively by the Chinese - who are using it for national security needs at this point. The nation spent $500 billion in clean energy - equal to the rest of the world.

It’s a common right wing/climate denier/faux concern troll line of attack against wind and solar that the materials can’t be recycled. What shows that these concern trolls are nothing more than that is that they don’t say the same things about the CO2 they’re creating.

Oh, just in case someone wants to whine about a fake thing - the cobalt that is in their phone/laptop batteries ARE NOT in power grid batteries. And are not in a majority of car batteries these days either.

Edit - solar modules will be 100% recyclableas well via multiple paths.

I’m still not sold on hydrogen being used for electricity or heating, but long distance trucking maybe. Definitely things like fertilizer, and industrial uses. I’m not certain who odd buying this hydrogen, so can’t secular there yet. But it’s in Lancaster which has a lot of industry, and it’s very near farm stuff too.

This project will be incentivized by the Inflation Reduction Act.

The amounts of space we have on oceans surfaces with more than enough offer, wind and solar generation opportunities to power the world. In fact, many times over - as well, all energy. at some point large scale, wind and solar using the same powerlines might become pretty consistent energy generators. Add in batteries and hydrogen maybe, and we’ve got a resilient system.

The key technology they’re seeking to develop are perovskite plus silicon tandem solar modules. I’ve read research suggesting this combination could reach up to 35% solar cells – meaning a 33’ish% solar module. Most solar panels today are about 20-22% efficient - reaching 33 - increase by about 50% - would probably drop the cost of solar electricity by 50% (different 50% numbers).
