Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
South Africa's power utility would do well to consider swapping out expensive new coal-powered capability for renewables.

The US was hit by a 'bomb cyclone' last week, bringing icy cold and driving snow. These storms develop very rapidly, forming outside the tropics, typically on continental east coasts in winter.
New modelling suggests that Australia could use renewable energy to hit its 2030 emissions reduction targets, without it costing any more overall than maintaining the status quo.
Meteorology researchers across the country are prepping experiments for the mini-night the eclipse will bring on August 21 – two minutes and 36 seconds without the sun in the middle of the day.
