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).

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
