This branch confused me. Not the kind of efficiency that I was asking about. This would actually be an advantage for countries that have a lot of hydropower. I think the advantage on this one would be for America (and perhaps Japan or some other places?) over China.
However the efficiency question I was asking about was the cost of building computing capacity that sometimes waits idly for the wind to blow versus the cost of batteries to keep the computers running. But on reflection I think the calculation is more complicated than I was thinking. There is also a savings from the idle time in that the servers are not wearing themselves out when they are just waiting. Also need to consider the cost of adding new servers over time. In general the CPUs are getting less expensive, but then you need to consider the value of getting the answers faster, and then you need to consider the possible advantages of thinking more carefully about which questions to ask in the first place...
