The EPA estimates that nearly 25 percent of the energy needs in the US are dedicated to lighting. Compact fluorescent bulbs are about 3 to 4 times more efficient than incandescent bulbs. The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself.
Fluorescent bulbs and Light Emitting Diode (LED) bulbs have revolutionized energy-efficient lighting. By switching from incandescent lighting to fluorescent lighting and LED lighting, the average consumer can save 50% to 80% in energy costs without any loss in lighting quality.
