Earth Hour 2016 will be held on Saturday 19 March between 8.30PM and 9.30PM in your local time zone. The event is held worldwide towards the end of March annually, encouraging individuals, communities households and businesses to turn off their non-essential lights for one hour as a symbol for their commitment to the planet.
Earth Hour is a worldwide grassroots movement uniting people to protect the planet, and is organised by WWF. Engaging a massive mainstream community on a broad range of environmental issues, Earth Hour was famously started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage more than 7000 cities and towns worldwide, and the one-hour event continues to remain the key driver of the now larger movement.
That is a decision that has to be made individually but usually the overhead lights in rooms (whether it is your house or a business), outdoor lighting that does not impact safety, decorative lights, neon signs for advertising, televisions, desk lamps, the list goes on and on.
There are a few lights we can say with certainty that should NOT be turned off, including safety lights in public spaces, lights for aviation guidance, traffic lights, security lights, just to name a few. We ask people to use common sense. Before you turn off any lights for public spaces, Earth Hour recommends you check with local officials or community centres.In your own home, use common sense with respect to safety. Keep small night lights on for basic safety especially in halls and on stairs.
Make sure you have alternative light sources handy before Earth Hour starts, like torches or flashlights. That way if you need to see, you have a light source close at hand, and you can still respect the spirit of Earth Hour and keep yourself and your family safe.
