Large-scale wind and solar power 'could green the Sahara'

Large-scale wind and solar power 'could green the Sahara'

Science
Installing huge numbers of solar panels and wind turbines in the Sahara desert would have a major impact on rainfall, vegetation and temperatures, researchers say.They found that the actions of wind turbines would double the amount of rain that would fall in the region.Solar panels have a similar impact although they act in a different way. The authors say their work reinforces the view that large-scale renewables could transform the Sahara region. The scientists modelled what would happen if 9 million sq km of the Sahara desert was covered in renewable energy sources. They focussed on this area because it is sparsely populated, and it is also exposed to significant amounts of sun and wind and is close to large energy markets in ...
