I think it is crazy for Al Gore to suggest that in 10 years from now, we will not be using any fossil fuels. That is apparently his goal, and politicians of the world over are clambering over each other to make more wildly ridiculous promises about 80% reduction in fossil fuels or a carbon neutral world. Personally, I do not think a carbon neutral world is feasible: Not with this many people, and not if people are going to bring themselves out of poverty in the developing countries. It’s just not going to happen, and maybe it isn’t necessary to have a carbon neutral world.
