Here’s a bright idea. Take a big step towards energy conservation in your home by switching to energy-efficient light bulbs. Because electricity in most households is still generated in power plants that burn fossil fuels, any wasted electricity, even in the home, can be extremely taxing on the environment—in terms of both resource depletion and carbon dioxide emission.



Quite simply, some light bulbs are less efficient than others. Incandescent light bulbs, the kind that fit into most household lamps, turn the vast majority of the electricity they consume—as much as 95%, according to one source—into heat, rather than light.



By contrast, compact fluorescent light bulbs (pictured), or CFLs, combine substantially increased efficiency with a significantly longer lifespan. Because of their increased efficiency, an 11-watt CFL, for example, will produce about as much light as a 60-watt incandescent bulb. And because of their longer lifespan, that same CFL should continue lighting up your room for as long as 15,000 hours, whereas your incandescent bulb is likely to last only about 1000 hours.
