But actually I find it rather scary. Because the fact is that it MUST be done. And even more than Gore is proposing -we shall need much more electricity in 2020 (cars really need to go electric until fuel cells can be developed). And not only in the US.
Suddenly, things like the quantity of steel required will be rather noticeable.

So, you are in effect saying that it is hard but actually possible to go most of the way of Gore's speech in the USA (already a major difference from conventional wisdom) provided we start right now, when we actually need to do more, and everywhere. And I don't see a major, worldwide program on the starting blocks.

We won't be able to say we weren't warned, either.

Still, a great response to those who claim it can't be done at all (hello, Mr. Jancovici).
