South Africans joined the rest of the world when they switched off their lights for Earth Hour from 20:30 to 21:30 on Saturday night together saving 410MW.

Each year on the last Saturday in March, South Africans join thousands of people around the globe and use their collective voice to inspire, motivate and lead the charge on their hopes, dreams and concerns about the planet.

In a statement Eskom said that it “encourages people to take action beyond this one hour and to make energy efficiency and envi­ronmental conservation part of their daily lifestyles.”

Earth Hour through the years

In 2017, 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.

In 2016, the country saved 575MW, which trumps the past two recorded years. Read more: Earth Hour: Re-think sustainable business designs and operations

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.
