"The total area of solar panels it would take to power the world"

[bricolage]

I saw this on a twitter account called Amazing Maps. It's a pretty powerful image but is it actually true? I know next to nothing about solar power but I'm hoping someone here can shed some light (ay ay, get it?!) on the whole thing.

Even if it were true, that "world" square is several hundred or thousand square kilometers. Hardly an easy matter to build a solar array that big.

several of them could probably be built that big when you think about how much other shit is built over the years all over the place

A world-wide, multi-national group of the developed countries could probably fund solar power for the rest of the world, let alone if every nation did what they could to put something into the project as well as take something out (the energy itself).

This seems even more plausible to me if the aim was to switch the sources of the world's energy to solar power and not attempt to increase the geographic area/quantity of those receiving the energy, yet.

How profitable would it be?

Isn't there also a problem with storing solar energy? Can't store the whole world's energy in batteries.
