South Africa suffers from crippling power outages, locally known as load shedding. In the first three months of 2021, load shedding occurred for 650 hours.
A wind turbine works by harnessing the power of the wind to create wind energy. The wind turns large blades around a rotor. This, in turn, powers a generator, which creates electricity.
South Africa is a coal-dependent country. Coal makes up 74 per cent of the country’s total electricity supply. In the first quarter of 2021, 81.8 per cent of South Africa’s electricity came from coal.
Greenhouse gases are gases that trap heat in the atmosphere. This can be any gas that absorbs infrared radiation and contributes to the Earth’s warming or the greenhouse effect.
Load shedding happens when selected sections of South Africa’s electricity grid are shut down. In literal terms, Eskom, the country’s power utility, “sheds” a certain “load” – or amount – of electricity from the national grid.
