Saturday 23rd March, 8:30-9:30 is Earth hour and it gives us a chance to turn off the lights and celebrate the dark. More than 2 million individuals and 2,000 businesses in Sydney took part in the First Earth hour in 2007. It has now grown to millions of people in over 5000 cities across 135 countries.
While Earth hour is here again, in its seventh year, the focus has changed shifting from just turning off the lights for an hour (which is still a good thing) toward a broader longer term approach to energy use. Looking at supporting renewable sources of energy supply like wind and solar.
