Energy efficiency

Switching to energy-efficient lighting in your home is one of the easiest things you can do to start saving energy and reducing carbon emissions. It’s also one of the fastest ways to cut your energy bill. Imagine illuminating your home using the same amount of light, but for less money.

An average household dedicates about 5% of its energy budget to lighting.
Smart lighting choices save you money. By replacing your home’s five most frequently used light fixtures or bulbs with models that have earned the ENERGY STAR®, you can save up to $75 each year. The most energy-efficient lightbulbs available today are CFLs and LEDs, both of which offer many choices that typically use 75% less energy. Energy-saving incandescent bulbs use about 25% less energy than traditional varieties.

What’s the Difference Between New Lightbulbs?

Incandescent bulbs use a lot of energy to produce light, with 90% of that energy consumed as wasted heat. (They are also no longer manufactured.)

Energy efficient lightbulbs, like light-emitting diodes (LEDs), halogen incandescent bulbs, and compact fluorescent lamps (CFLs):

  • Provide choices in illumination levels and the light's color appearance
  • Can initially cost more, but will save you money, use less energy, and last longer
  • Can be used with outdoor fixtures and will save energy, versus other "always on" bulbs. 

CFLs and LEDs are also available as floodlights and can be used in exposed fixtures to withstand weather. Look for ENERGY STAR®–qualified fixtures that are designed for outdoor use and come with features like automatic daylight shutoff and motion sensors.

CFL Light Bulbs

  • Use less electricity than traditional incandescent bulbs and can pay for themselves in less than nine months
  • If Energy Star®–qualified, use about one fourth the energy and last 10 times longer than a comparable traditional incandescent bulb that puts out the same amount of light
  •  Contain a small amount of mercury; they should always be recycled at the end of their lifespan 
  • See EPA's website for more information 

LED Light Bulbs

  • If Energy Star®–-qualified, use only 20%–25% of the energy and last up to 25 times longer than traditional incandescent bulbs
  • Use 25%–30% of the energy and last 8 to 25 times longer than halogen incandescent bulbs
  • Are one of today’s most energy-efficient and rapidly developing technologies
  • Work well indoors and outdoors because of their durability and performance in cold environments
