Read here. As has been written before, using crops to feed cars instead of mouths is an unmitigated disaster for multiple reasons. The only explanation that the biofuels industry survives is the Obama Democrats need to enrich its billionaire supporters and its big business friends in the agriculture sector.
Study after study has documented the complete waste that the biofuels effort represents, with the latest by Bryan et al., again providing the proof that only taxpayer funded subsidies keep this unconscionable renewable energy effort afloat.
"...as they [researchers] describe it, "assessed the potential benefits, costs, and trade-offs associated with biofuels agriculture to inform bioenergy policy.".....The three Australian researchers report finding that "biofuels agriculture was more profitable over an extensive area of the most productive arable land," producing "large quantities of biofuels" that "substantially increased economic profit." But they add that the end result was "only a modest net GHG [greenhouse gas] abatement" that had "a negligible effect on net energy production." In addition, they indicate that the economic profit was largely due to "farm subsidies for GHG mitigation," and that whatever benefits were accrued came "at the cost of substantially reduced food and fiber production."....."if biofuels are to be embraced," as Bryan et al. comment in concluding their assessment of the issue, "additional policy design features and institutions are required to support farm subsidies.""
