Energy use dimmed during Earth Hour

Following up article about the Earth Hour event.

Energy authorities say the impact of last night's Earth Hour event was the equivalent of two large power stations being temporarily shut down.

National landmarks like the Sydney Opera House and Melbourne's Federation Square were dimmed, as lights were switched-off across the country to help combat global warming.

Paul Bird from the National Electricity Market Management Company says it prompted a sizeable drop in demand for power.

"We're still finalising the data, but we do believe that there was at least 1,000 megawatts reduction across the national grid, which is a significant reduction across the states, south-eastern and eastern states of Australia," he said.

Earth Hour encouraged people to turn-off lights and electrical appliances for an hour, to help combat climate warming.

Mr Bird says demand dropped during the hour, but then rose again.

"There was a significant energy reduction, not only in the capital cities, we also detected it across regional centres as well,'' he said.

We participated last night, we turn off all lights and unplug unnecessary electricity for an hour then out for dinner.

If we all stick together, we can make a CHANGE!
