Summary: Residential and commercial lighting uses about 5% of U.S. electricity (EIA) and 10% of a households electricity (EIA-RESC). Since LED (light-emitting diode) bulbs use so much less electricity than other types of lighting and replacing older bulbs with LEDs is so cheap and simple, this solution should be implemented immediately.
LEDs last 20 times as long as incandescent bulbs and use about 1/4 of the energy for the same amount of light (DOE). California put in place high efficiency standards for lightbulbs January 1, 2018, which meant that only compact fluorescent (CFC) and LED bulbs could be offered for sale. Compact fluorescents are half as efficient as LEDs (WBUR) and also have a toxic disposal problem because of small amounts of mercury in the bulb.
In 2015, only 29% of U.S. households had even one LED lightbulb (EIA-RESC).
Goal: Substitute LED lighting for older types of bulbs in all possible fixtures in and outside of buildings (residential, commercial, industrial, government, street lighting).
