No. The main point of Earth Hour is to show the world that a solution to the world's environmental challenges is possible if we work on them together - together our actions add up!

Earth Hour only asks that you turn off non-essential lighting. This does not mean you have to turn off your refrigerator, but we do encourage you to be part of this global action by switching off your lights, as well as making a commitment to go beyond the hour with a long-term behavioural change.

Safety and security lighting should remain on.
