Can solar energy be used over the Sahara Desert?

Harvesting the globally available solar energy (or even just that over the Sahara) could theoretically meet all humanity's energy needs today (Hu et al., 2016; Li et al., 2018). Large-scale deployment of solar facilities over the world's deserts has been advanced as a feasible option (Komoto et al., 2015).

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.

Could large solar farms in the Sahara Desert redistribute solar power?

Large solar farms in the Sahara Desert could redistribute solar power generation potential locally as well as globally through disturbance of large-scale atmospheric teleconnections, according to simulations with an Earth system model.

Do solar farms cover the Sahara Desert?

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).

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.

Can large-scale solar farms influence atmospheric circulation in the Sahara Desert?

Our Earth system model simulations show that the envisioned large-scale solar farms in the Sahara Desert, if covering 20% or more of the area, can significantly influence atmospheric circulation and further induce cloud fraction and RSDS changes (summarized in Fig. 7) across other regions and seasons.
