CFLs use one quarter of the energy of a comparable incandescent bulb. Each CFL can save more than 400 pounds of coal over its lifetime.
Most electricity in NC comes from burning coal, oil and other fossil fuels. This creates
pollution that contributes to ozone, haze, climate change and other air quality problems. If every NC home replaced just one standard bulb with a CFL, it would reduce the amount of carbon dioxide released into the air by 217 million pounds per year.
CFLs last up to 10 times longer than standard
bulbs, and each CFL saves about $40 in electricity over its lifetime.
To replace standard soft white bulbs, choose a warm white or soft white CFL. For brighter light for reading and tasks, choose a cool white or daylight CFL.
All fluorescent light bulbs- including CFLs- contain small amounts of mercury, so recycle or dispose of them properly. Using CFLs actually reduces mercury in the environment,
because burning coal for electricity produces mercury, and CFLs save so much electricity.
