Change a Light Bulb

If every household in America changed just one traditional light bulb to a energy-efficient compact fluorescent bulb at home, combined efforts would save 5.6 billion kilowatt-hours of electricity per year or $526 million a year in electric expenses. This would save enough energy to light more than 2.5 million homes for a year and prevent greenhouse gases equivalent to the emissions of nearly 800,000 cars.

CFL light bulbs use 2/3 less energy than standard incandescent light bulbs and last up to ten times longer. Replacing a 60-watt incandescent with a 13-watt CFL can save consumers at least $30 in energy costs over the life of the bulb. CFLs last longer and come in different sizes and shapes to fit almost any fixture. Additionally, CFLs produce about 70% less heat than standard incandescent bulbs, so they are safer to operate.

Take the "Change a Light" Pledge

157,055 people like you have taken this important step. Collectively, they have pledged to change 320,965 bulbs. That means we will avoid using 90,512,130 kWh of energy and prevent 142,829,425 lbs of greenhouse gas emissions.
