Massive solar and wind farms could bring vegetation back to the Sahara

Tierr@_de_N@die: Crazy idea or this article is pointing to a near future where the country's wealth would be linked to solar and wind resources instead of fuel resources? This really could turn upside-down the geopolitics in the zone.

Wind farms largely cause temperature increases because their turbine blades bring warmer air down to the surface, especially at night. This has been observed in field studies and using remote sensing. They have also been shown to increase moisture in the air.

Solar panels mean more solar radiation is absorbed and less of the sun’s energy is reflected back into space. This causes the land surface to warm up. Several studies have shown this, including one which showed that the effect of warming caused by fossil fuels, via carbon emissions, was 30 times greater than the warming caused by solar photovoltaics absorbing more solar radiation. However, temperature effects may vary within the solar park and with season.
