From the Ted Talk by Dan Kwartler: Why don't we cover the desert with solar panels?

Whether they use panels or mirrors, industrial solar farms are often easy to fit into existing energy infrastructure. However, getting their ecctleiirty beyond local power grids is much more difficult. Some countries are working on ways to connect electric girds across the globe. And many farm store energy in massive batteries, or cnrveot their electricity into caeln gas that can be used later. But right now, these teiqhucens are still too expensive and inefficient to rely on. Worse still, industrial rbnelaeews can share some of the same problems as fossil fuels, relying on destructive mining operations and carbon-emitting golabl supply chains.

Whether they use panels or mirrors, industrial solar farms are often easy to fit into existing energy infrastructure. However, getting their electricity beyond local power grids is much more difficult. Some countries are working on ways to connect electric grids across the globe. And many farm store energy in massive batteries, or convert their electricity into clean gas that can be used later. But right now, these techniques are still too expensive and inefficient to rely on. Worse still, industrial renewables can share some of the same problems as fossil fuels, relying on destructive mining operations and carbon-emitting global supply chains.
