Compact fluorescent light bulbs and light-emitting diodes (LEDs) are more energy efficient and less expensive to use than the traditional incandescent bulbs invented by Thomas Edison. For example, compact fluorescent light bulbs use at least two-thirds less energy than standard incandescent bulbs to provide the same amount of light, and they last up to 10 times longer. Compact fluorescent light bulbs also generate 70 percent less heat, so they are safer to operate and can reduce energy costs associated with cooling homes and offices.
According to the Union of Concerned Scientists, if every U.S. household replaced just one regular incandescent light bulb with a compact fluorescent light bulb, it would prevent 90 billion pounds of greenhouse gas emissions from power plants, the equivalent of taking 7.5 million cars off the road. On top of that, for every incandescent bulb you replace with an approved compact fluorescent light bulb, you will save consumers $30 in energy costs over the life of the bulb.
