Energy is cheap; people are expensive. One kilowatt hour costs about ~80 seconds of a human's time, if the kwh and the human are both in Chicago and the human gets federal minimum wage and costs nothing in overhead.
(Any human fitting this definition is also spherical and frictionless, i.e., existing nowhere outside of physics textbooks.)
Bonus points: this remains true if one does not value money but one instead counts costs totally in carbon credits, which is one of those things that the environmental movement passionately believes and yet doesn't spend much time thinking of the implications of.
