Increasing our use of domestic alternative fuels like ethanol can help diversify and secure our energy supply. Growth in ethanol production and use has already helped to decrease reliance on crude oil imports.  In 2005, the year the Renewable Fuel Standard (RFS) was adopted, America’s net dependence on foreign petroleum peaked at just over 60%. The RFS has had a dramatic impact on our nation’s energy security and diversity. Net petroleum import dependence fell to just 25% in 2015, but would have been 32% without the addition of 14.8 billion gallons of domestically produced ethanol to the fuel supply.



Reducing America’s addiction to imported oil is important not only because of the risk that foreign governments will reduce supplies and raise prices, but also because of the dangers of shipping the oil from troubled regions such as the Persian Gulf.

FACT: Without 14.8 billion gallons of domestic ethanol used in the U.S. in 2015, the United States’ net import dependence would have stood at 32% instead of 25%.

The surge in ethanol production has reduced gasoline imports from nearly 10 billion gallons in 2005 to almost zero today. Looked at another way, the ethanol produced in 2015 displaced an amount of gasoline refined from 527 million barrels of crude oil.  That’s roughly equivalent to the volume of oil imported annually from Saudi Arabia and Kuwait combined.

FACT: We are dangerously dependent on petroleum from volatile areas of the world.

Military leaders from all branches of the U.S. armed forces have recognized that our addition to foreign oil presents real dangers to our national security, economy and environment.  Secretary of the Navy Ray Mabus has said, “When we did an examination of the vulnerabilities of the Navy and Marine Corps, fuel rose to the top of the list pretty fast.  We simply buy too much fossil fuel from actual and potentially volatile places.  We would never allow somoe of these countries we buy fuel from to build our ships, our aircraft, our ground vehicles – but because we depend on them for fuel, we give them a say in whether our ships sail, our aircraft fly, our ground vehicles operate.”

FACT: Global fossil fuel subsidies reached almost half a trillion dollars in 2010. This figure is up $110 billion over 2009 and could reach $660 billion by 2020.

FACT: According to the Congressional Research Service, $46.6 billion in tax expenditures has been granted to fossil fuels 1977-2010, and  more than $130 billion in government subsidies have gone to the oil industry from 1968-2000, as detailed by the U.S. General Accounting Office.

This does not take into account the billions spent since the turn of the century or the money spent to protect our military troops in the Middle East.

“With more research and incentives, we can break our dependence on foreign oil with biofuels…We need to get behind this innovation. And to help pay for it, I’m asking Congress to eliminate the billions in taxpayer dollars we currently give to oil companies. I don’t know if you’ve noticed, but they’re doing just fine on their own. So instead of subsidizing yesterday’s energy, let’s invest in tomorrow’s.”  Source: President Barack Obama, State of the Union Speech, January 25, 2010.

FACT: Ethanol constitutes a large and growing share of domestically produced fuel for gasoline-powered vehicles.

Ethanol presents the U.S. with a critical opportunity to expand domestic energy production and reduce imports.  Ethanol now accounts for one out of every four gallons of fuel offered for gasoline vehicles from domestic energy sources.   

FACT: All oil-related external costs are estimated to be $825 billion per year.

The U.S. spends between $27 billion and $137 billion a year on military operations securing the safe delivery of oil from the Persian Gulf, equivalent to adding an extra $1.17 per gallon of gasoline. And new oil supplies are getting harder and more expensive to find. Nonconventional reserves, like Canadian tar sands, pose significant environmental and economic risks.
