But there's no reason to not use resources we already have at hand? And what you're suggesting would be better handled with government research grants or private investing.

What are renewables?

Solar panels last for 25-years and there is no set recycling method for them.

Wind turbines need consistent maintenance and blade replacement. Old blades go to the trash heap. Still only 12% efficient when they're working.

Biogas essentially creates CO2 in the process, and even more when its methane constituent is burned. And the process usually requires more energy than burning CH4 yields... aka non-renewable.

Geothermal... for now, I guess. Entropy will inevitably win that race, however, and our unifying, warm little rock will freeze.

Hydrothermal... for now as well.

Even thorium, with its large abundance, is finite in availability.

So what is a renewable energy source in a grandeur scheme?

Uranium isn't infinite either, however we can build reactors that basically use nuclear fuel to create even more new fuel. It's not perpetual energy but it's about the closest thing.

Fusion would run on the most abundant atoms in the universe. It's a technology that's "just 20 years away" and has been since the 70s, but it should become viable sometime this century.

The point I'm making is your "urgency to optimize renewable technology" shock and awe is well-scripted and hasn't been the answer for over a decade now. It's time we allow nuclear fission to be the answer, as a society. Can we decide on that?

Except we've already reached 'peak oil' in terms of usage due to the advent of electric/hydrogen transportation. The pipeline is being funded by the private sector, and will increases the efficiency/reduces ghg emissions from the transport of the fuel.

Renewables are not going to be able to replace fossil fuels until we have good storage options. They're already cheaper than fossil fuels, and we'd be shutting all of our coal plants down if renewables were reliable enough.
