WHAT'S IT ABOUT?

WWF’s Earth Hour is a unique annual phenomenon that focuses the world’s attention on our amazing planet, and how we need to protect it. At 8.30pm on 23 March hundreds of millions of people turned off their lights for one hour, on the same night, all across the world in a huge, symbolic show of support.

For 2013 as we all switch off our lights, we want the focus to be on the kind of energy we use. Because to create a better future for our planet we need to move away from dirty fossil fuels and onto clean green renewable energy which works with the awesome power of nature, not against it.

It's not too late to join millions worldwide who want a bright future for our planet. Sign up and add your name to our UK map.
