Indeed, which is why a careful examination needs to be made of the energy and resource cycles involved. It'll be interesting if we ever switch to an energy economy fuelled entirely by PV (or similar), and seeing how the energy economics plays out. This is aside from the various minerals needed to continually replenish our new green energy sources, and what we do with the complex and poisonous wastes produced. As for your comments on China - they certainly don't have any issues allowing widespread pollution and industrial poisoning of their people and land. >The whole 'it's all powered by fossil fuels' argument is a bit old now It'll only be "old" when China reduces the amount of coal (and mostly brown coal) that it uses to manufacture all this stuff for us. They have enormous reserves, it won't happen any time soon.
