Earth Hour 2014
On March 29, 2014, hundreds of millions of people around the world in over 7,000 cities in 162 countries turned off their lights for Earth Hour, our annual display of commitment to protect the planet.
In the United States, we made a big statement to the world on how much we care about the planet. Over 50,000 people joined the movement along with major landmarks, cities and businesses, including the Golden Gate Bridge in San Francisco, the Chrysler Building and the Empire State Building in New York, the Willis Tower in Chicago, the Gateway Arch in St. Louis, the National Cathedral in Washington, D.C., and the Space Needle in Seattle just to name a few.
Now that the lights are back on, you can go beyond the hour with simple changes to reduce energy consumption year-round.
