Cape Town, March 20 (IANS) South Africans actively took part in the Earth Hour campaign by switching off lights from 8.30-9.30 p.m., saving an average of 515 mw electricity during the hour, authorities said on Sunday.
As part of its support for the Earth Hour campaign, the country's electricity utility Eskom measured the reduction in electricity used during the hour on Saturday, Xinhua reported.
"We would like to encourage people to take action beyond this one hour, and to make energy efficiency and environmental conservation part of their daily lifestyles," Eskom said.
People are encouraged to reduce their energy consumption every day by using electricity efficiently, and switching off all non-essential lights and household appliances, said the utility.
Commercial customers, particularly shopping centres and office blocks, can also make a big difference by switching off non-essential lights and not leaving office equipment such as computers in standby mode after hours, it added.
Earth Hour is an annual global event, initiated in Sydney, in 2007 to encourage people to switch off lights and unused appliances for an hour as a symbolic demonstration of their commitment to action against climate change. (IANS)
