Now in its 4th year – Earth Hour has continued to spread across the globe, but participation in Australia appears to have decreased from previous years. In this article we compare reported electricity savings during the past 4 Earth Hour events, and look at the effects of Earth Hour on the NEM in 2010.







Earth Hour 2007 – Impact on Australia’s National Electricity Market
