otherwise be used to fix infrastructure, create jobs, pay for teachers, etc.,
Instead of just buying a barrel of oil, refining it and burning it, they have to buy oil, turn it into fertilizer, transport that to the fields and grow a lot of corn, (which has its own separate set of payments of taxpayer money to large business concerns) which requires more oil, then transport it to the refinery where more energy is used to create the ethanol...
Well, you get the idea. When we were cut off by OPEC it became one of many solutions to gain our independence (again), but when that ended they lowered the price of oil and everyone forgot about all the alternative energy research. (Well, except for China who just announced a $1.5 trillion investment into strategic industries, one of them being alternative energies, but I digress). The people who had invested in ethanol got a congressperson or two to argue their case and, slither, they got their tentacles into the public's money.
There are far better uses for that land, including sustainable farming which doesn't require the petroleum-based fertilizers and weed killers that are nearly ubiquitous in our food supply.
It also has some effect on prices, but most people miss the fact that because the rules protecting us from commodity hoarders (developed back in the early 1900's, like the ones that were removed to allow Wall Street to create the depression we are in now)were changed about 10, maybe 20 years ago, so speculators do far more to drive up prices than demand and supply now does. Quite sad, actually, because those price swings in petroleum and food are nothing more than a hugely regressive tax on those that can least afford it. Yet politicians routinely use the supply\demand arguments because they want the donations of the wealthy, which would likely cease if they were honest about the cause of their prices rocketing up.
Hope that helps.
