It's clear there is an energy positive in producing ethanol.

Ethanol is, in its pure form, just as much of a sham as oil.

It's extraordinary how inventive one can be with ethanol right now.

Ethanol has reduced our nation's dependence on imported energy, created thousands of jobs, reduced air pollution, and increased energy security. And renewable fuels cost less at the pump. It is a growth fuel that fuels opportunities for millions of Americans.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

Ethanol and biodiesel allow people to burn a cleaner form of energy.

Certain food-based biofuels like biodiesel have always been a bad idea. Others like corn ethanol have served a useful purpose and essentially are obsoleting themselves.

Ethanol reduces our dependence on foreign sources of oil and is an important weapon in the War on Terror. By investing in South Dakota's ethanol producers, we will strengthen our energy security and create new jobs.

Corn ethanol can help in the short term, but it has serious limitations, and none of this is going to work if we don't dramatically improve the efficiency of our cars and trucks.
