ThinkGeek's carrying a line of simple, low-priced LED light-bulb replacements. They last ten years and draw one thirtieth of the power consumed by incandescents. I think the only downside here is that something that's this long-lived is bound to be obsolete long before it's burned-out. That's the green paradox: green manufacturers focus on long-lived tech because that's good for the landfills, but they also do such good R&D that the next generation of products is often miles better and miles longer-lived, which presents the dilemma of throwing away green technology before it's used up in order to replace it with wildly more efficient successor technologies.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
