Exactly this. We can't focus on reducing costs easy, what we can is focus on obtaining energy easy and clean. Civilisation energy demands will only grow. So focusing on web taking 1% less energy will not be as impactful to all of us as pushing for more green energy.

I think the biggest issue now is not ability to generate energy ( we have passive and active green energy sources ) but Storage.

And It would probably be for the best to find kinetic ways to store and release energy. Ofc I might be wrong and in the end batteries and solid state batteries solutions might be the winner. But I think kinetic storage is kinda low hanging fruit not many companies are looking into.

Also kinetic energy storage usually shouldn't degrade as fast as fluid based batteries.
