Yeah that is nuts. That China you dislike, well I got some of their panels and batteries and elasticity increased supply while now I suspect I will net profit from my electricity supplier. May have to tell the tax man!

So scale that up and you could produce GW of power with solar batteries and throw in some wind and longer storage (gravity or hydrogen) and maybe a backup gas for like a rare week of no wind or sun.

And you can just keep scaling up. It is the AWS of power.
