I read an article about this last month... and just recently saw it on TV as well.
If each household in america were to change a single lightbulb to the new "compact flourescent" type (Ya' know... the little twisty spiral bulbs) the energy savings and resulting reduction in pollution would be equal to taking 11 million cars off the road.
So please kids... tell your parents. The bulbs don't cost but a few dollars more to buy. They last for years so you rarely ever have to replace them... and they will lower your power bill.
I switched every single bulb in my little apartment to one of these... and my power bill dropped by $20 a month. Think of what you guys living in 2-3 bedroom houses can save by simply changing your lightbulbs.
