Earth Hour

Tonight is Earth Hour – an opportunity to send out a big message about our commitment to cutting our energy usage and safeguarding the future of our planet. Earth Hour is asking you to turn off your lights and non-essential electrical appliances at 8pm (your local time) tonight.

The first Earth Hour was held in Sydney, Australia between 7:30 pm and 8:30 pm on 31 March 2007. The 2007 Earth Hour is estimated to have cut Sydney’s mains electricity consumption by between 2.1% and 10.2% for that hour, with as many as 2.2 million people taking part.

You’ll all have noticed that Google has turned the lights out on their homepage today!

Of course: this won’t really cut energy usage or help the climate. Because the power stations will still be running and producing the same amount of energy. But this is an opportunity to send out a really strong message to others and to our neighbours and to raise awareness of climate change issues. So I’ll be participating in Earth Hour from 8pm to 9pm tonight and I call on readers to join in!
