Covering the sahara with solar panels

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.

Could solar power the Sahara Desert?

In reality, we would harvest so much more energy than we could ever possibly need. According to Forbes, solar panels covering a surface of around 335km 2 would actually be enough to power the world – this would cover just 1.2% of the Sahara Desert. What would happen? Outside of electricity generation, this could have several consequences.

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.

Why do we not cover the desert with solar panels?

Why don't we cover the desert with solar panels? Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That's well over 100 times more energy than humanity consumes annually.

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.

Can solar power be harnessed in the Sahara?

For perspective, the sun delivers an mind-blowing 173,000 terawatts (TW) of solar energy to Earth continuously, more than 10,000 times the world’s current energy consumption. A study published in the journal Renewable and Sustainable Energy Reviews explores the feasibility of harnessing solar power from the Sahara.
