Switching to LED bulbs saves money and the planet
Conservation February 26, 2020

Solar panels and wind turbines get a lot of attention these days, but a more common medium is helping reshape America’s energy economy right now: The simple light bulb.

In fact, there’s been a quiet light bulb revolution in the United States over the past decade, with many homes moving to more energy-efficient lighting. That general shift has already decreased electricity demand in the country.

According to the Natural Resources Defense Council, there are about six billion screw-in sockets in homes across the United States and two to three billion of those still have inefficient incandescent or halogen bulbs in them. 

LEDs, or light-emitting diodes, are the most efficient light bulbs on the market, according to the Department of Energy. They use up to 85 percent less energy than traditional incandescent bulbs, the ones with a thin wire filament inside, and can last up to 25 years. 

If every home in the country switched those sockets over to LEDs at once, we’d save an estimated 38 million tons of carbon dioxide emissions a year. 

If that doesn’t sound like much, it’s equal to the emissions from about seven million cars and the United States would save about $14 billion on lighting annually. On a personal level, every household could save roughly $100 a year on its electrical bill, depending on variables like electricity rates where a person lives, etc.

The cost of LEDs tends to be higher than traditional incandescent bulbs, but that’s rapidly changing as technology improves.
