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.
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.
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.
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).
By examining the large-scale remote responses induced by Sahara solar farms in S20 SST, we find that the precipitation and wind anomalies seen in S20 are significantly dampened when the ocean response to local changes and associated ocean–atmosphere interactions are limited (Figure 1f; Figure S3f).
However, by employing an advanced Earth-system model (coupled atmosphere, ocean, sea-ice, terrestrial ecosystem), we show the unintended remote effects of Sahara solar farms on global climate and vegetation cover through shifted atmospheric circulation.

In 2022, Switzerland derived 6% of its electricity from solar power. Studies show that installing solar panels on mountaintops in the could produce at least 16 terawatt-hours (TWh) a year, approaching half of the nation's 2050 solar energy target. Typically, solar panels in Switzerland are mounted on existing infrastructure like mountain huts, ski lifts, and dams, with larger-scale installations in the Alps remaining rare. [pdf]

Although the proportion of solar heat to overall consumption in Switzerland is still relatively low, its potential is considerable. If all existing buildings were to be optimally improved in terms of energy efficiency, it would be possible to meet the heating requirements of all Switzerland's households through the use of solar collectors.

Selenkei Investment Ltd is a special purpose vehicle incorporated in Kenya to develop, construct and operate a PV solar power plant. . FMO’s funding will be used to construct a 40 MW PV solar power plant. The project site is located close to the city of Eldoret in Western Kenya. . West Kenya is in need of additional power complementing the existing hydroelectric power plant in the region. The project will supply renewable energy to the national. . This project has a low environmental and social risk with main impacts deriving from the construction activities of setting up a PV plant and are confined to general. [pdf]
KenGen is seeking to build a 40MWp floating solar PV power plant on Kamburu Dam, which would make it Kenya’s first grid-level floating solar plant.
Power firm Ecoligo GmbH built Kenya’s first floating solar PV plant in 2021. The small 69kWp plant was installed on one of the reservoirs at Rift Valley Roses farm in Naivasha. The energy produced by the solar system is solely for self-consumption and is not fed back into the grid.
Two of the projects, developed by Mauritius-registered Radiant Energy and Eldosol Energy Limited, are sited next to each other some 13 kilometres to the south east of Eldoret town in Uasin Gishu county. Another solar power plant is being developed by Alten Energy Solarfarms. It will be located just 1 km east of the Radiant/Eldosol sites.
“A floating solar photovoltaic project with a capacity of approximately 40MWp is currently being developed by KenGen,” said the firm in a notice. Kamburu is one of the Seven Forks Dams along the Tana River. The dam powers a 94.2MW hydroelectric power station that was commissioned in 1974.
