Energy saving lightbulbs are available for every type of location, lamp, and use. Bulbs that are dimmable, that fit in your ceiling fan, outdoor lights, track lights, fixtures, and lamps.
Let's take an example.
You live in Illinois, and you want to change out TWO 6-watt bulbs for compact fluorescents. Over the life of your new bulbs, you will save $44.93 in your energy bill. And you'll be doing the country a favor, because you will stop 670 pounds of greenhouse gas from going into the atmosphere.
So do it. Where? Lots of places.
One of the country's leaders in selling and making the lightbulbs easy to find is Wal-mart. In 2006 Wal-mart put on a campaign to sell to every one of its 100 million regular customers just ONE compact fluorescent bulb. Yes, they are doing it to make money. And yes, they are doing it to save energy as well, which saved Wal-mart. The company anticipated a $2.6 million saving from changing its refrigerator-case lightbulbs in 500 stores.
You can also buy the bulbs from Home Depot, Walgreens, CVS drugs, KMart, Target, and many other stores.
How can you help the world, too? According to the EPA,
"If every American home replaced just one light bulb with an ENERGY STAR qualified bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars."
