The Power of Negawatts: Energy Efficiency

Reducing the impact of our use of energy is one of the key technical, political, and even moral challenges facing human society in this century. While our sources of energy have to be made cleaner, our first priority must be to use energy more efficiently. Efficiency measures are cheaper, cleaner and faster to install than any other energy option. And we lose nothing in the bargain – the point of efficiency is to allow us the same levels of productivity or comfort, but with less power.
