What would happen if the Sahara desert was covered in solar panels?
Covering 20\% of the Sahara with solar farms raises local temperatures in the desert by 1.5°C according to our model. At 50\% coverage, the temperature increase is 2.5°C. Roughly the same amount of additional rainfall that falls over the Sahara due to the surface-darkening effects of solar panels is lost from the Amazon.

How much would it cost to cover the Sahara Desert in solar panels?
This idea, known as “agrophotovoltaics,” has been touted in solar circles as a way of boosting land use efficiency by 60 percent. The above image, from the Sahara Forest Project, would cover 10 hectares in Tunisia and cost $30 million, and would use the solar energy to help cultivate the crops.
What if we covered the moon with solar panels?
The construction would stretch for 11,000 km (6,800 miles) along the Moon’s equator, and would reach 400 km (250 miles) in width. That’s enough to cover half of the US. With nothing but lunar soil and gravel, they’d make concrete, ceramics and solar cells.
How much of the Sahara Desert would we need for solar power?
If we covered just 1.2 percent of the Sahara desert in solar panels, we could harness enough of this power to meet the energy needs of the entire world. It wouldn’t be easy, though. How would we overcome the geopolitical and financial obstacles involved?
Do We Own the Sahara Desert?
We don’t own the Sahara desert. The Sahara is “owned” by Africans in at least 11 countries. Many of those countries are not exactly paragons of political stability (e.g. Sudan, Egypt, Libya, Sudan, Tunisia). The good news is, you don’t need a lot of the Sahara covered with solar to make a huge difference.
Could we power the world’s largest desert with solar power?
Researchers imagine it might be possible to transform the world’s largest desert, the Sahara, into a giant solar farm, capable of meeting four times the world’s current energy demand. Blueprints have been drawn up for projects in Tunisia and Morocco that would supply electricity for millions of households in Europe.
Why are solar panels made in the desert?
Deserts are spacious, relatively flat, rich in silicon – the raw material for the semiconductors from which solar cells are made — and never short of sunlight. In fact, the ten largest solar plants around the world are all located in deserts or dry regions.
