Narrator: Doing something good for the planet is easier than you think. Just turn off the lights while you watch your favorite show. If we all turn off two lights in our homes for an hour everyday, we'll save more than five billion kilowatts of electricity nationwide each year. The amount of coal it takes to produce that much electricity could fill up the Empire State Building, almost three times.
When we work together to conserve, we can all enjoy a healthier, brighter future. This Earth week, pledge to turn the lights off any time your screen is on. You could win an energy efficient TV and other green prizes. Help spread the word. Lights off, screens on.There may be small errors in this transcript.
