USE LOW-ENERGY
LIGHT BULBS
A simple environmental measure that will save money is to replace traditional, incandescent
bulbs with low-energy versions.
They use 80 percent less electricity than incandescent bulbs but produce as much light – a 20-watt energy-
saving bulb is equivalent to a traditional 100-watt bulb. They are also designed to last far longer – five or even
10 years – than traditional bulbs.
Changing just one incandescent light bulb to a low-energy light bulb in every home in the U.S. would save
about 62 million kilowatt hours over the lifetime of the bulbs, which is enough energy to light about 32,000
homes for a year.
