How Many Lightbulbs Does it Take to Change the World? One. And You're Looking At It. Very interesting article in the August issue of Fast Company about Walmart's huge push to sell 100 million compact florescent lightbulbs in the next 12 months (one to every customer).

"...if every one of 110 million American households bought just one ice-cream-cone bulb, took it home, and screwed it in the place of an ordinary 60-watt bulb, the energy saved would be enough to power a city of 1.5 million people."
