Replace light bulbs with LEDs. Light-emitting diodes last 25 times as long as incandescent bulbs. They also use less energy than compact fluorescent light bulbs and lack the toxic mercury found in CFLs.

Generate energy with solar panels, wind turbines or geothermal systems—or all three. Which technology would work the best in the Washington climate? Which one would generate the most energy for the least amount of money? It's an energy showdown on the White House lawn.
