Switch your incandescent bulbs to compact fluorescent (CFL) bulbs. CFL bulbs use a fraction of the energy of their incandescent counterparts, produce 70% less heat, and last ten times longer than traditional bulbs. All this saves you $30 or more over the life of each bulb.
Prices of CFL bulbs have dropped. They now cost nearly the same as their less-efficient incandescent bulbs. Where a CFL will cost you $10 in electricity during its lifetime, an incandescent will use up $40 in the same time period. If every American home replaced just one light bulb with a CFL bulb, the Untied States would save enough energy to light more than 2.5 million homes for a year.
Kids have a habit of leaving lights on. Teach them not to. Better yet, install occupancy sensor switches to automatically shut off the lights when people leave the room. They’re ideal for mud rooms, powder rooms, playrooms, garages, basements, and anywhere else your kids — or you! — may forget to turn off the lights.
Tip: Dimmer switches can save energy and extend bulb life. The energy saved is not quite proportional to the amount you dim. A light dimmed down to one quarter of its input still uses half the energy.
