"Cost" data, in particular, should include direct and indirect industry subsidies in addition to the direct and indirect energy cycle effects. I smell fifth columns and a "giant sucking sound." One "research group" representative declared that some number in the billions of "gallons" (no BTU's or other equivalent measure was mentioned) of ethanol could be produced from "switchgrass" and other "cellulosic" materials--but no mention of the effects of such production on ecosystems and not even the simple arithmetic of how much acreage would be required. And, of course, no mention of the energy and resources required to produce, distribute, and put such energy to "useful" work. What kind of taxpayer-supported subsidies are going to Archer-Daniels Midland (ADM) an other corporate entities now, and what kind are in the works or will be in the works when this shell-game finally shakes out? (Can you spell "overruns?") Of the 6,000-plus ECOLOG subscribers, how many think ethanol production, particularly as an end product rather than a by-product, is a significant "solution" to "the energy crisis" and how many think it is a juicy pork-barrel (or something else) AND upon what scientific or evidentiary basis?
