WWF Australia is holding Earth Hour later this month, which invites all households and businesses across Australia and the globe to turn their lights off and their appliances off standby for one hour at 8pm on March 29. Research has shown that if Australia’s commercial sector turned off its lights when buildings weren’t in use, and combined this action with other energy efficient technologies, it could reduce lighting emissions by up to 70 per cent, saving 10 million tonnes of greenhouse gas emissions. Earth Hour aims to demonstrate how easy and cost efficient these changes can be.
