Use LED Light Bulbs
LED light bulbs are extremely energy efficient and long-lasting; an LED bulb can cut energy consumption by over 80% when compared to conventional light bulbs and can last up to 25 longer. A US Department of Energy study found that LEDs installed in 2012 saved around $675 million in energy costs. You can help by swapping an LED bulb for any regular light bulb at home.
If every American replaced one conventional light bulb with an LED, the energy savings could light an estimated 2.5 million homes.That’s the equivalent to the greenhouse gas emissions of 800,000 cars. For more information on the benefits of using LED bulbs, visit energy.gov.
