Did you ever notice that the only kind of energy environmentalists don't mind wasting

... is human energy?

Environmentalists in the main genuinely detest devices (such as automobiles or dishwashers) that save human energy, and often (especially in such tools as dishwashers) save water and fuel energy. But I've found that environmentalists tend to have a sort of Ghandian vision of a world made up of small villages in which people work long hours on subsistence crops and live short lives. Tools that take us out of that sad vision are the ones they hate.
