With gas prices soaring and concerns mounting over U.S. dependence on foreign oil, ethanol is gaining traction as a viable solution. Ethanol is a clean-burning, high-octane fuel derived from plants like corn, offering environmental benefits and reduced reliance on Middle Eastern oil.
Ethanol has evolved significantly since its introduction in the 1970s. The industry now projects over 5 billion gallons in annual production, primarily used to enhance gasoline’s octane rating. Common blends include:
* **E10:** 10% ethanol, 90% unleaded gasoline. Approved for all U.S. vehicles, it’s praised for performance and clean combustion. In 2004, about one-third of American gasoline contained ethanol, mostly in this blend.
* **E85:** 85% ethanol, 15% unleaded gasoline. Designed for flexible fuel vehicles (FFVs), with over 4 million currently on U.S. roads and increasing.
Ethanol boosts octane, cuts fuel costs, and reduces emissions. An American Coalition for Ethanol (ACE) study found that $20 of E10 allows vehicles to travel farther than with regular gasoline. ACE’s VP of Market Development, Ron Lamberty, highlighted ethanol’s lower cost-per-mile and potential for cheaper prices at the pump.
Midwestern E10 prices are often $0.10/gallon lower than unleaded. A Consumer Federation of America study suggests ethanol blending can reduce pump prices by up to $0.08/gallon.
The future may see ethanol replace, not just supplement, petroleum-based fuel. Proponents envision energy independence, lower gas prices, enhanced national security, rural job creation, and environmental protection.
Brazil, a long-time ethanol user, provides a successful example. Their “flex-fuel cars” run on gas, ethanol, or a mixture. The U.S. already has similar flex-fuel technology, with GM and Ford introducing it years ago; currently three of every four new cars sold in the U.S. have the flex-fuel technology.
President Bush stated, “Ethanol will replace gasoline consumption. Ethanol is good for the whole country.”
