Could large-scale solar panels cover the Sahara Desert?

Large-scale photovoltaic (PV) panels covering the Sahara desert might be the solution for our electrical requirements, but it could also cause more trouble for the environment. An EC-Earth solar farm simulation study reveals the effect of the lower albedo of the desert on the local ecosystem.

Do we need 100% of the Sahara to be covered in solar panels?

We don’t need 100% of the Sahara to be covered in solar panels. Even 20%, which is the amount that would kickstart these impacts, is not needed. Instead, a series of smaller solar farms covering 1.2% of the surface should be enough to generate enough electricity without having such extreme impacts on the environment.

Could teleconnections affect solar farms in the Sahara Desert?

Large-scale photovoltaic solar farms envisioned over the Sahara desert can meet the world's energy demand while increasing regional rainfall and vegetation cover. However, adverse remote effects resulting from atmospheric teleconnections could offset such regional benefits.

Could the Sahara be transformed into a solar farm?

In fact, around the world are all located in deserts or dry regions. it might be possible to transform the world’s largest desert, the Sahara, into a giant solar farm, capable of meeting the world’s current energy demand. Blueprints have been drawn up for projects in and that would supply electricity for millions of households in Europe.

What happens if we cover the Saharan sand?

Outside of electricity generation, this could have several consequences. First, the light colour of the Saharan sand serves the purpose of reflecting the sun’s light and heat back into the air. By covering this, we would be ensuring that more sunlight is absorbed, thus prompting a rise in ground temperature.
