When I ask people what they think are the two cheapest, cleanest, safest,
most environmentally friendly, and most reliable energy technologies
available today, the answer I receive is almost always wind and solar. But
the correct answers; conservation and efficiency; have nothing to do with
generating electricity. And the first step to utilizing these technologies
is to commit, individually and collectively, to making a coherent and
lasting reduction in our consumption of energy.
