The "cheap energy" metrics tend to look at the cost per kWh delivered when the intermittent generators are producing. I've seen the estimates on the cost of "solar/wind plus storage," and I remain somewhat pessimistic that those will actually be delivered, at those costs, in quantity. The easy answer here is to simply use energy when it's available. I do this in my office. It's a bright, sunny day, and I have a bunch of extra compute rigs doing assorted BOINCy tasks at the moment, though sometimes they do video transcode or other things. When it's a dark winter day, I use a lot less energy. And before getting too excited about the state of lithium energy storage, grab yourself a copy of Cobalt Red by Kara. It's an exceedingly disturbing read on the state of cobalt mining in DRC.
