Global organisers of Earth Hour, a grass roots movement for the environment asking people to switch off electricity for an hour on 24 March, say they hope to energise millions of people and that “every action counts”.

Landmarks go dark for Earth Hour in 2016.

The event, now part of WWF’s campaign to highlight the dangers of climate change, has seen the lights go out in participants’ homes and at global landmarks for one symbolic hour every year since 2007.

Officially, the event takes place “wherever in the world you are at 8.30pm for you” – but many people will be marking the hour at different local times.

If you are getting involved, we’d like you to tell us how and to hear some of your most inspiring ideas ahead of the event. Are you going further than switching off lights and other electrical products in your home? Maybe you’ve persuaded other people such as colleagues, friends or fellow members of a community organisation to take part?
