It's not free, but it's the good part nonetheless - nuclear energy and thus increase in people trained to operate and build nuclear reactors.

Nuclear energy is, planning-wise, very high quality, you have a lot of control in scaling the output.

That allows, together with lots of accumulators of various kinds (pumping water up and such), to actually make renewables with uncontrollable output useful.

Making the average cost of energy better than just that of nuclear.

So, when Microsoft dies, those reactors and people will be of value.
