Compact Fluorescent Light bulbs (CFLs) use 66%-75% less energy than a standard incandescent bulb and last up to 10 times longer. Replacing a 100-watt incandescent bulb with a 32-watt CFL can save $30 in energy costs over the life of the bulb.
As a result of technological advances, new CFLs are much less expensive than they used to be. They also start more quickly without flickering; and the light they cast is visually much warmer and more appealing than it was years ago.
There are LED Light bulbs available that use even less energy than CFLs and can last for many years. While LED bulbs remain a more expensive incandescent alternative than CFLs, LED manufacturing technology is improving every day.
Installing higher efficiency bulbs will also save time as you won't have to change them nearly as often as incandescent bulbs.
Step 1: Choose the correct bulb and wattage for each receptacle in your home.
Step 2: Take out the old bulbs from their receptacles and put in the new bulbs.
