A 'green' shopping list ranges from LEDs to solar panels

Many of us are not likely to sit down and craft a "green" shopping list. But it's not a bad idea to mull over what you might want or could afford. "Almost every product I have bought in recent years has been purchased to save me energy and money," said Jim Detjen, Knight Professor of Environmental Journalism Emeritus at Michigan State University. Among other things, he and his wife, Connie, have replaced all of their incandescent lightbulbs with either compact fluorescent lightbulbs, or more recently LED bulbs.
