Led's: Heroes Of Efficiency

The Cheapest, Simplest and Quickest way of saving Money,
. . . is to become more efficient with our use of energy.
Light-emitting diodes, or LED light bulbs are quickly becoming more affordable and
. . . even more efficient than compact fluorescent bulb, or CFL.
Today, the average efficiency of an LED lightbulb is about 100 lumens per watt,
. . . about 20% higher than the LED lights available just last January.

The more energy efficient a home is, the less electricity it consumes.
. . . And that means fewer carbon dioxide emissions from coal-fired power plants,
. . . as a way to combat climate change.
