The Sahara Desert, Credit, TED Ideas. The Sahara''s reputation rests of the fact that it is the largest hot desert on earth, and both Greenpeace and IEA see it as a tool to exploit the energy from the sun.

Learn MoreThe average solar panel absorbs light from the sun and converts around 15-20 percent of it into electricity. The rest of the sunlight is converted into heat and released back into the environment. This heating could become problematic in the Sahara Desert as the panels are darker than sand and would therefore absorb more heat.
Yes Method Screened for originality? Amassing the available solar energy over the Sahara desert, through the installation of a large-scale solar farm, would satisfy the world's current electricity needs. However, such land use changes may affect the global carbon cycle, possibly offsetting mitigation efforts.
Another hindrance to the functionality of the panels would be the dust and sand becoming accumulated on the solar panels. As we could see, the conditions of the desert would not necessarily bring out the best in the solar panels.
In our model, for instance, if the solar farms do not cover a large enough fraction of the Sahara desert (20% coverage or more), then the responses are quite muted (e.g., the S05 scenario, Text S3).
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.
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. As if that weren't enough, extreme weather cycles would become more frequent, having terrible consequences for human populations.
