LEDs use 90 percent less energy than incandescent bulbs for the same amount of light
Project Drawdown, LED LightingAs 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 LightingResidential LEDs - especially ENERGY STAR rated products - use at least 75% less energy, and last up to 25 times longer, than incandescent lighting.
Energy.govImpact 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
