Study: Large-scale wind and solar farms in the Sahara would increase heat, rain, vegetation

07.09.2018 | University of Illinois | illinois.edu

Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial – or detrimental – to the regions in which they are situated. A new climate-modeling study finds that a massive wind and solar installation in the Sahara Desert and neighboring Sahel would increase local temperature, precipitation and vegetation. Overall, the researchers report, the effects would likely benefit the region.

The study, reported in the journal Science, is among the first to model the climate effects of wind and solar installations while taking into account how vegetation responds to changes in heat and precipitation, said lead author Yan Li, a postdoctoral researcher in natural resources and environmental sciences at the University of Illinois.

How will solar farms influence Sahara

The wind and solar farms simulated in the study would cover more than 9 million square kilometers and generate, on average, about 3 terawatts and 79 terawatts of electrical power, respectively.
