ELI5: Why don't we cover the Sahara desert in solar panels to power the earth?

It's a lot of unused empty space that sees a lot of sunlight could we not even use some of it to generate power?

Because the Sahara desert isn't where we need the electricity.  Solar panels require a lot of space per watt, and then transferring that energy to someplace that will pay for it causes lots of energy loss.  

There are more profitable deserts in southern California, closer to people who will pay for electricity.
