LED bulb

Switching your lightbulbs to energy-efficient LED’s does not just lower your electric bills. It also reduces carbon pollution and global warming.

Ralph Cavanagh of the Natural Resources Defense Council says LED’s are one of many recent innovations in energy efficiency. When used by homeowners, businesses, and utilities, the benefits quickly add up.

Cavanagh: “When I started my work in the seventies, everyone assumed that in order for economic growth to occur, energy use had to grow just as fast or faster. And on that logic, a healthy and growing economy meant an inexhaustible appetite for giant new polluting power plants. Coal and nuclear were the typical orders of that time. What’s happened since is an energy efficiency revolution that has completely broken the linkage between energy use and economic health. Since the mid-nineteen-seventies, the U.S. economy has more than tripled in size, but total energy use is up less than thirty percent.”

Coal still supplies a lot of the nation’s energy. But as the U.S. transitions to more wind and solar, Cavanagh says efficiency remains important.

Cavanagh: “Energy efficiency improvements allow that clean energy to go further.”

So changing lightbulbs helps create a brighter, cleaner energy future.
