Save With LED Lights

LED lights are the most energy-efficient bulbs available. They use 90 percent less energy than incandescent bulbs for the same amount of light. Unlike older technologies, most of the energy LEDs use goes into creating light, rather than wasting energy on heat. Almost any bulb currently in use can be replaced by LEDs, and they come in many different styles and tones. They might cost a bit more than a regular bulb, but they last much longer and will save you money in the long run.

  • LEDs use 90 percent less energy than incandescent bulbs for the same amount of light
    Project Drawdown, LED Lighting

    As LEDs replace less-efficient lighting, 10.2–10.8 gigatons of carbon dioxide emissions could be avoided in residences and 5.9–6.7 gigatons in commercial buildings.
    Project Drawdown, LED Lighting

    Residential LEDs - especially ENERGY STAR rated products - use at least 75% less energy, and last up to 25 times longer, than incandescent lighting.

  • Impact metric calculations

    To determine the carbon emission reduction estimates related to switching to LED lights, the following calculation was performed:

    (hours of bulb operation /day) x (number of bulbs to be replaced) x (days/year) / (months/year) x (W of Current bulb - W of LED bulb) x (0.475 kg CO2e/kWh) / (1000 Wh/kWh) = kg CO2e / month
