Lighting may account for as much as 20 percent of the energy use in your home. According to the Department of Energy, new, more energy efficient lighting options allow you to have the same amount of light in your home for less money.
You may still have a few around your home, but the old, incandescent bulbs you’ve relied on for years to produce light are no longer being manufactured. Now, look for LEDs and CFLs to save energy and lower your bill.
According to Energy Star, high quality (or Energy Star®-qualified) LED bulbs:
- Use at least 75% less energy than incandescent lighting.
- Last 25 times longer than incandescent lighting and about two to five times longer than fluorescent lighting.
- Give off light in a specific direction, so they are more efficient than incandescent and fluorescent bulbs which waste energy by emitting light in all directions.
- Operate more efficiently, with little wasted heat, so they also can reduce cooling costs and are cooler to the touch.
- Are more durable. They don’t contain glass components so they won’t easily break like conventional or CFL bulbs.
According to Energy Star, high quality (or Energy Star®-qualified) CFL bulbs:
- Are simply small versions of the long fluorescent tubes you often see in a kitchen or garage.
- Are not as efficient as LEDs, but use 25%-35% of the energy used by incandescents to provide a similar amount of light. They also last about 10 times longer (7,000-24,000 hours).
- Contain a small amount of mercury, so they should be disposed of properly when they break or recycled at end of use. See the EPA's website for more information.
