Two LED lightbulbs!
"We're also giving employees in most of our offices around the world next-generation, super-efficient LED light bulbs to encourage energy efficiency. (LEDs use up to 90% less energy than incandescent bulbs and 50% less energy than a CFL.) In the average U.S. home, lighting accounts for about 20% of the electricity bill. If every Googler changes out one incandescent light bulb for one of these LEDs, the combined impact would be the equivalent of taking over 4,000 cars off the road for one year!"
(In case you're intereseted, the bulbs come from Lemnis Lighting.)
