Earth Hour 2015

Thank You For Participating!

On March 28, 2015, hundreds of millions of people around the world in over 7,000 cities in 172 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. Major landmarks, cities and businesses joined the movement, including the Empire State Building in New York, John Hancock building in Chicago, Gateway Arch in St. Louis, hotels and casinos along the Las Vegas Strip, National Cathedral in Washington, D.C., Los Angeles Airport, and the Space Needle in Seattle just to name a few.

Now that the lights are back on, we can build on Earth Hour’s momentum and work together to create a better future.

Let's Go Beyond the Hour

Tell President Obama to Take Strong Climate Action.The US is uniquely poised to help drive climate action at home, and at the same time, rally other countries to make commitments to fight climate change. Sign our petition to President Obama and tell him you support his Administration moving as quickly and aggressively as possible to reduce US carbon emissions and contribute its fair share to helping the world face down the threat of climate change.

Learn what you can do to help fight climate change in your community and at home. Each and every one of us can continue to engage in the movement to help animals, people and nature by taking these eight steps to fight climate change:

  1. Sign up for an energy audit for your home. Often these are free from your utility and they'll help you find ways to cut energy use and save money, too!
  2. Lower the thermostat on your hot water heater to 120 degrees Fahrenheit.
  3. Unplug all appliances when you’re not using them, and turn off your computer and monitor when you no longer need them. Contrary to popular belief, turning them on and off will not cause damage.
  4. Wash clothes in cold water (especially clothes with vibrant colors). This not only reduces hot water usage, but it is better for your clothing as well.
  5. Air dry dishes rather than using the heated drying cycle in the dishwasher.
  6. Buy products that have the Energy Star label on them. All Energy Star products meet strict guidelines set by the US Department of Energy.
  7. Bike, walk or take public transit to work one day (or more!) per week.
  8. Buy renewable energy from your energy provider. Most utilities offer this option, and it is usually not much more expensive than paying for dirty energy.

Earth Hour is a great reminder that by uniting and connecting behind a common purpose we can make a meaningful difference. Not just for one hour, but every day. Thank you for participating in Earth Hour this year. We are honored to have you standing with us in action.
