LED Bulbs
75% less energy, 25x longer life. Saves $225/year per home.
LED bulbs use 75% less energy than incandescent and last 25,000 hours—25 times longer than a traditional bulb’s 1,000-hour life. By 2027, widespread LED adoption in the US could save the equivalent of 44 large power plants’ annual output, making this swap the highest impact per dollar.
