25 March 2013 – South Africans switched off and achieved a massive 629 MW average reduction on their electricity usage during this year’s Earth Hour between 8:30 pm and 9:30 pm on Saturday, 23 March 2013.
In 2012, Eskom measured an estimated reduction of approximately 402 MW during the hour-long campaign – enough electricity to power the city of Bloemfontein. Eskom measured the reduction in electricity used during the hour against typical consumption for this time on an average Saturday evening.
Eskom had also switched off non-essential lighting at all its offices around the country, except at strategic facilities for security reasons. Eskom’s support is in line with the 49M energy efficiency movement that was launched in March 2011 by deputy president Kgalema Motlanthe and minister of public enterprises, Malusi Gigaba. The campaign encourages individuals and businesses to lead energy-smart lifestyles, to save power, save the planet and save their pockets.
