10 Easy Ways to Save Money & Energy in Your Home
3. Replace incandescent light bulbs.
The average household dedicates 11% of its energy budget to lighting. Traditional incandescent light bulbs convert only about 10% of the energy they consume into light, while the rest becomes heat. The use of new lighting technologies, such as light-emitting diodes (LEDs) and compact fluorescent lamps (CFLs), can reduce the energy use required by lighting by 50% to 75%. Advances in lighting controls offer further energy savings by reducing the amount of time that lights are on but not being used.
Here are some facts about CFLs and LEDs:
CFLs use 75% less energy and last about 10 times longer than traditional incandescent bulbs.
LEDs last even longer than CFLs and consume less energy.
LEDs have no moving parts and, unlike CFLs, they contain no mercury.
