Powering the Future

A new book hints at the alternative-energy sources we may soon be tapping into.

Chances are you’ve heard of hybrids and biofuels, but what about oil-producing yeast and turbinelike buoys that transform ocean waves into electricity? Those are just a couple of the alternative-energy sources that may power the future according to Fred Krupp, president of the Environmental Defense Fund and coauthor, with Miriam Horn, of the new book “Earth: The Sequel” (Norton).

“Everyone knows the current story of melting glaciers, rising sea levels, worsening hurricanes, dying coral reefs,” said Krupp. “‘The Sequel’ is the story of what happens next. We are just on the threshold of a great race.” While he says oft-cited solar power technology is our best bet for now, Krupp emphasizes that quirkier projects, like algae concoctions that eat up carbon emissions, are essential elements of a smart, diversified energy strategy. NEWSWEEK’s Katie Paul talked with Krupp about why he thinks the next industrial revolution looks bright green. Excerpts:

NEWSWEEK: You seem to be a big fan of solar energy. Why do you think there’s so much promise to it?
Fred Krupp: We have two chapters on solar energy at the beginning of the book because we think there’s tremendous potential there. Every hour, the sun provides the earth with as much energy as all of human civilization uses in an entire year. So, if you could capture just 10 percent of it on a piece of 100-mile square piece of land, you could power the entire United States.
