Gerhard Knies, a particle physicist, sat down one day and worked out that in just six hours, the world''s deserts receive more solar energy than the entire human race consumes in a year. The energy needs of the world could be met by just covering 1.2 percent of the Sahara desert in solar panels. So why haven''t we? Some people have tried. The ...
If 1.2% of the desert—around 110,000 square kilometers—is covered with solar panels, it would be enough to satisfy the entire world’s energy needs. In addition to this, the desert has extremely low rainfall, little to no cloud cover, limited wildlife and negligible human populations.

An EC-Earth solar farm simulation study reveals the effect of the lower albedo of the desert on the local ecosystem.
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.
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.
According to German physicist Gehrard Knies, in just six hours, deserts around the world receive more solar energy (173000 terawatts) than humans consume in a year. (Source) The Sahara Desert in Africa is 9.2 million square kilometers in size, occupying 8% of the land mass on Earth.
Deserts are spacious, relatively flat, rich in – the raw material for the semiconductors from which solar cells are made — and never short of sunlight. In fact, around the world are all located in deserts or dry regions.

If the Sahara Desert was covered in solar panels, it would have the potential to generate enough power for the entire world. However, this would only be possible if the solar panels covered a very large surface area – around 335km2. This would only be a tiny fraction of the Sahara Desert, meaning that most of the desert would still be available for other uses. …
Covering a large part of the Sahara Desert with solar panels could significantly impact regional climates and ecosystems. The desert surface has an albedo value, or sunlight reflection capacity, of between 30-40%. Solar panels could reduce this value to 5-10%, causing the surface to absorb more heat and potentially increasing regional ...
Even covering 20% a fifth of the Sahara Desert with solar panels would result in higher global temperatures. Polar regions will also be affected, provoking more sea ice melts and rising sea levels. So even with the best intentions, installing solar panels in the Sahara may defeat the object.
Solar panels enveloping only 1.2% of the desert could possibly produce sufficient power to supply the whole world. The elevated levels of solar radiation at the Sahara turns it into a brilliant site for employing solar energy, as well as an initiative of this level appears to be a rational step to an environmental future.
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 …
The Sahara Desert receives an abundance of solar energy, raising the possibility of covering it with solar panels to solve global energy problems. However, there are limitations to solar panel efficiency and challenges associated with large-scale solar farms, such as heat absorption and environmental impact. Alternative solutions, such as concentrated solar power plants using …

So r RealLifeLore decided to ask a key question: What would happen if we covered the Sahara desert with solar panels? No area in the world gets more sun a year than the Sahara desert. On ...
Why the Sahara Desert Solar Panel Idea Should Be Abandoned in Favor of Smarter Solutions. The concept of putting solar panels over the Sahara desert is instead an interesting thought experiment, but it is not practical due to environmental, practical, and economic problems. This project poses potential risks, interfering with the subtle balance ...
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....
Researchers have calculated that if the Saharan desert is covered with solar panels, it will generate four times the world''s demand for electricity. Imagine how life would be easier! The unit price of energy will be reduced considerably.
Hence, building solar panels throughout this desert will be marvellous. Then, what is stopping us? Researchers are sceptical about the impact of covering the entire desert with solar panels. To realise the issue, we need to understand the solar panels first. Solar panels are flat surfaces containing photovoltaic cells that can trap energy. The ...

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.
Proposals to blanket the Sahara Desert with solar panels, while ambitious, verge on fantasy when examined closely. Such plans overlook critical environmental, technical, and logistical challenges, which could transform a seemingly promising idea into a catastrophic misstep. Here''s why this concept is more "Alice in Wonderland" than a feasible solution for …

Difficulty transporting solar panels to desert. To even set up the solar farms in the first place, a colossal effort would have to be made. We are talking about providing enough solar to power the entire world. That''s a lot of solar panels. Around 51.4 billion 350W solar panels, over an area of 115,625 square miles.

Desert solar farm. Image used courtesy of Unsplash . So, why haven''t we covered every inch of the desert with solar panels? Defining Deserts . Deserts are defined by the amount of precipitation they receive (less than 25 cm a year). This means many areas can be labeled as ''deserts,'' even if they aren''t the hot, sand-covered areas we ...
