South Africans saved 350 MW – enough electricity to power the city of Bloemfontein – when they switched off their lights during Earth Hour this weekend, power utility Eskom said on Tuesday.
As part of its support for the Earth Hour campaign, Eskom measured the reduction in electricity used during the hour against typical consumption for this time on an average Saturday evening.
Eskom’s support is in line with the 49M movement launched recently by Deputy President Kgalema Motlanthe to mobilise South Africans to save electricity.
“We encourage every South African to ‘lift a finger’ − which is all it takes to switch off a light when it is not in use. Simple actions, such as using compact fluorescent lamps instead of incandescent globes, keeping unused appliances switched off, adjusting the thermostat on your geyser and switching it off when we leave for work and turning it on before we go to bed. Reducing electricity wastage can have a dramatic impact on electricity consumption. If you are not using it, switch it off,” said Eskom CEO Brian Dames.
In 2010, Eskom measured an estimated reduction of approximately 420 MW during the hour-long campaign.
