As the price of solar energy technology drops, people are finding creative ways to tap into one of our most abundant resources. Just how much of our energy can come from solar and will it truly be accessible for all? We'll visit a "solar sheep farm" in eastern North Carolina that's boosting renewable energy and grass-fed lamb production. In Atlanta, Georgia, Interfaith Power & Light works with congregations that feel a moral obligation to clean up the planet. And we check out creative applications of solar, from solarized stadium car parks to community solar for all.
