Oil is the cheapest form of energy we have less nuclear power.
Already, even Minnesota "land of 10,000 lakes" is reported as having possible conserns with water usage because of ethanol production for it takes at least 2 gallons of water to produce 1 gallon of ethanol fuel.
We aren't doing well by oil usage, not because we are dependent but because we are strapped by bureaucrat's stifling personal freedom by "dictating" via directive to not allowing us to use our own resources available to obtain safe and secure energy.
Windmills "ain't" going to cut it, we have the technology even superior to French technology to use nuclear energy and the available oil domestically to shame those who we buy it from.
It's that d@mn directive word that gets in the way every time. ; )
Do you have a source for that statement? Subsidized corn derived ethanol is a waste.
