These farms could increase rain in the Sahara, especially in the neighbouring Sahel region, a semiarid area that lies south of the giant desert.
This increase of precipitation, in turn, leads to an increase of vegetation cover, creating a positive feedback loop.
If solar & wind farms covered >3.4 million sq. miles of the Sahara. On average, the wind farms would generate 3 terawatts, while the solar farms would generate 79 terawatts of electrical power in 1 year.
In 2017, the global energy demand was only 18 terawatts, so that is obviously much more energy than is currently needed worldwide.
Winds farms would cause localised air temperatures to warm.
The increase of rainfall & vegetation, combined w/ clean energy as a result of solar & wind energy, could help agriculture, economic development, & social well-being in the Sahara, Sahel, Middle East, & other nearby regions.
The Sahara has been expanding for some decades, & solar & wind farms might help to stop the expansion of it.
