Advocates for 100 percent renewable energy often compare the effort needed to meet that goal to efforts to put a person on the moon.
The truth is this: We’re closer to 100 percent renewable energy today than we were to the moon in 1961, when President Kennedy made his famous pledge to land there by the end of the decade.
Here’s another truth: It’s not going to be pretty. We have unleashed powerful climactic forces that can’t just be shut off like a dirty, obsolete coal plant. Every day those forces are intensifying and interacting in ways that profoundly affect people right now. We can no longer afford to debate whether we should or can’t pull off this monumental task. We must focus on how to achieve it – and on that front, there’s more reason for optimism than you might think.
JFK didn’t have the blueprints for the Apollo landing craft in his pocket when he said: “I believe this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth.” But within a remarkably short time, we have developed the technologies that can free us from the dirty, dangerous and expensive energy sources of the past.
