"Man Acts"

Interestingly, Ludwig von Mises has a concise response to the claim that we can obtain 100% of our electricity needs from renewable, non-biofuel sources; man acts. That is, human action can be independent of solar and wind patterns, and hence no matter how good solar, wind, and hydro power work, we can pull a trick and load down the system beyond what it is supplying.  Hence we need some "on demand" systems and/or storage.

One would figure a guy smart enough to get a professorship at Stanford would figure this out, but apparently there's a lot of politics involved in getting an office in Palo Alto where ability in logic is not necessarily a requirement.
