Reply #3: There is some elasticity

[pscot]

in the relation between energy consumption and GDP, so an 88% cut in energy input wouldn't necessarily mean an 88% cut in GDP. Further, an 88 % cut in Greenhose Gas Emmissions doesn't mean an 88% cut in energy. There will be some substitution of non-polluting sources for carbon sources. So David Warren is just pulling numbers out of his ass. But while Warren may be an ignorant, lying sack of shit, he's right about one thing. An 88% cut in the use of carbon based energy is going to cause a lot of pain and economic dislocation. Probably even a world depression.
