On Saturday, South African’s switched off their lights for one hour to participate in a global awareness campaign, Earth Hour.

South African state-owned power utility, Eskom, recorded that through this initiative, the country ‘saved’ 420MW, enough to power a city the size of Polokwane or Port Elizabeth for an hour.

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 would like to encourage people to take action on climate change beyond this one hour and to make environmental conservation part of their daily lifestyles. Read more…

In 2016, the country saved 575MW, slightly higher than this year. At the time, Siddarth Das, executive director of Earth Hour Global, said in a statement: “Earth Hour reminds us that while people are on the frontlines of climate change, they are also our first-line of defence.”

What is Earth Hour?

Earth Hour, which started in Sydney, Australia, in 2007, is organised by the World Wide Fund (WWF) as a lights-off event to raise awareness about climate change.

Currently, more than 162 countries and territories worldwide are part of this initiative, which engages a massive mainstream community on a broad range of environmental issues.

People are encouraged to switch off lights and unused appliances for an hour as a symbolic demonstration of their commitment to action against climate change.
