Green Living Feature of the Week - CFL Lighting


One of the easiest ways for environmentally conscious people to make a difference is by using Compact Flourescent (CFL) bulbs for lighting.  I've used them exclusively in place of incandescent bulbs for about 5 years now, and love them.  They are more expensive, but they last 10 times longer than incandescent bulbs.  More significantly, they consume about 75% less electricity.  An incandescent bulb is very inefficient; it is essentially a heating element in a vacuum tube.  Most of the energy is converted to heat; light is almost a by-product.  CFL's run much cooler, converting more energy to light.  Not only do they help the environment, they save the consumer a lot of money.

I saw an impressive statistic, that every household in the U.S. replacing one incandescent bulb with a CFL would result in the same emission reduction as taking 1 million cars off the road. 
Wow-- think of the effect of replacing ALL incandescents with CFL's! 

CFL's do contain some mercury, so they should be recycled rather than thrown in the trash.  I'm taking them to the local Home Depot; all of their stores accept CFL's.   If there is not a store locally, the Earth911.com website shows nationwide recycling locations for almost all recyclables.

The next generation of energy efficient lighting is LED (light emitting diode) lighting.  The LED runs even cooler and uses even less power than the CFL, but is more expensive.  Recent improvements in LED technology should reduce prices as production increases.
