98 per cent of South Africa’s water resources are already<br />
being used. Future economic development will<br />
depend on sustainable water management.<br />
A coal-fired power plant uses 530 litres of<br />
water to power a single home for<br />
a month. Photo-voltaic (PV)<br />
cells only need water<br />
when the panels<br />
are washed.<br />
renewable energies, like PV solar power,<br />
not only combat climate change but can also<br />
conserve scarce water supplies in dry countries<br />
like South Africa, by replacing coal, oil and nuclear<br />
power plants that need water for cooling<br />
