A world without continuous energy is a world without computers - i.e., a 
world without *me*. ;-)

Besides, the sun *is* a perfect source of energy. It's not quite 
continuous across the whole planet, but every other lifeform manages to 
cope with that.

Nobody is going back there.

I agree that living in one place and commuting to another place to do 
your day's work is a pretty stupid idea. As is importing toothbrushes 
from China rather than making them in the UK.

On the other hand, for any given town or city, only a finite amount of 
land is available. Can you really manufacture absolutely everything 
needed within that space? Probably not. You ought to be able to manage 
quite a bit of it, though.
