Now scientists have finally completed research that shows ethanol is not only bad business but also bad for the environment. According to news reports, the latest issue of Science magazine highlights studies showing that biofuels produce more greenhouse gas emissions than fossil fuels when all of their production inputs are accounted for. …

Two studies shows that replacing fossil fuels with corn-based ethanol would double greenhouse gas emissions over the next three decades. The studies show that switchgrass, an alternative to ethanol that’s more weed than plant, would boost emissions by 50%.

How? It’s because, as I described in my piece, so much energy is required to fertilize, harvest and refine the fuels. It’s also because the growing of fuel plants replaces the growing of vegetation that actually consumes harmful greenhouse gases.
