Could Solar PV Power the World?

This map from data supplied by the International Energy Agency (IEA) and interpreted by Land Art Generator shows the area required to provide all the electricity needed in the world from solar PV.

One flaw- they suggest that Europe could be supplied from the Sahara desert - but as we know, peak consumption in Europe occurs after dark, and the sun has set even in the sunny Sahara at that time.

All is not lost however - the deserts of USA are still sunny at peak times of European consumption, so all we need is a link from the USA to Europe - see my blog on an Arctic Circle supergrid.

If you don't like the idea of linking the world up like this, then you and the rest of us are going to have to shift a whole lot of consumption out of the after dark peak. Have you told your friends yet?
When I suggest this, people often say storage is the answer - which at the moment is much more costly than nuclear.

So I say  Reassess, Reduce, Reschedule!
