How many light bulbs does it take to change the world?

At 8.30pm this Sat March 23, millions of Earthlings will switch off the lights for Earth Hour, in a symbolic act of solidarity for climate action.

It’s a great chance to show our leaders that we humanoids DO care about the planet, and to raise public awareness about climate change and sustainability at the same time.

And this year, Earth Hour is ramping it up, challenging people to go beyond the hour and switch off for good by switching over to renewable energy. So we thought we’d turn it over to you to make the switch to GreenPower and then let the pollies know you want Australia to be green powered!
