Home energy use can be responsible for more than twice the greenhouse gas emissions of the average car. By using energy more efficiently at home, we can lower our energy bills while also helping to reduce the risks of global climate change.

You can help change the world. You can save energy and help preserve the environment with a simple twist of the wrist. Lighting, which accounts for 20 percent of the average home's electric bill, is one of the easiest and most effective places to start saving. Just one compact fluorescent light bulb (CFL) can save an average of $30 or more in electricity costs over its lifetime and prevent more than 450 pounds of greenhouse gas emissions.

From Oct. 1 through Dec. 31, 2009, participating Iowa electric utilities are helping residents make the simple switch to energy-efficient lighting by offering special pricing on ENERGY STAR® qualified CFL purchases of 12 bulbs or less. With this special pricing, the bulbs will sell for as little as $0.99 at select retail locations.
