In this series published in Bulletin of the Atomic Scientists, Amory Lovins joins three other atomic experts in discussing ideas for how to curb carbon dioxide emissions, reduce global temperatures, and sustain economic growth. Lovins’ proposed solution is to stop wasting energy. He points out that saving energy is cheaper than buying it, a concept that makes environmental and economic sense. He argues that the climate problem is not necessary or economically sensible; it is an artifact of wasted energy and money. When we take steps to save energy, we will also be saving money and the climate.
