This is an expanded version of an article that was published in the Bulletin of the Atomic Scientists, in which Amory Lovins joins three other atomic experts in discussing ideas for how to curb carbon dioxide emissions, reduce global temperatures, sustain economic growth, and summon the necessary political leadership. Lovins’ creative 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 protecting against climate change.
