@kkarhan @karolherbst @ShadowJonathan while a decent idea the environment in the western Sahara is not conducive to large scale solar power due to the large amount of particulate that will dull and wear the mirrors (or PV cells in the case of PV power generation). Any scale large enough for global power supply would need massive amounts of infrastructure to sustain itself let alone transit the stored energy.

The best option for large scale fully renewable power generation is likely going to be free floating off shore wind farms. These could also help power desalination and hydrogen fuel generation on the shore and offer non-centralized generation (safer against attacks or localized disasters) and decreased need for transport (Less transit infrastructure means lower overall impact to environments).
