With credit to Ameren, here is what it said:
"Even one person switching to compact flouescent lighting will save money and give the environment a boost. If every American home replaced just one traditional bulb with an Energy Star-qualified CFL, we would save more than $600 million on annual energy bills and enough energy to light more than 3 million homes for a year. Why CFL's are a bright idea
- CFL's use 75% less energy than incandescent bulbs
- CFL's last up to 10 times longer than incandescent bulbs, and produce less heat
- You can save $30 to $60 over the life of each CFL bulb you install
- CFL's help reduce the demand for electricity, which in turn helps delay the need for new power plants."
