Getting the government out of the business of mandating certain kinds of fuel is very important.
There are a number of reasons the RFS harms Americans. A recent Congressional Budget Office report concluded that complying with the mandated volume levels would increase the price of diesel by 30 to 51 cents per gallon and regular gasoline by 13 to 26 cents by 2017. These price increases will hurt all Americans, especially people on fixed incomes.
Further, the RFS continues to mandate a product on the American people. Like Obamacare, the government should not dictate what products consumers must use. The American people should be free to choose which fuels work best for them, not government bureaucrats.
