A retired U.S. Navy vice-admiral urges the continued expansion of the biofuels industry to enhance U.S. national security and help ward off threats from petroleum-exporting countries with opposing political views to the U.S.

“Those who wish to do the U.S. harm can exploit our vulnerability of our single mindedness on fossil fuels as our energy portfolio,” Vice-Admiral Dennis McGinn said during the 2012 Biomass Conference in Washington, D.C. in July.

McGinn’s point is from a report called “Powering America’s Defense: Energy and the Risks to National Security” written by McGinn and other retired military three- and four-star admirals and generals who concur on energy, the environment, and national security.

“(The issue is about) expanding the (United States) portfolio of energy beyond petroleum. That is what biofuels are all about,” McGinn told the crowd of 700. “I am not talking just ethanol, just algae-based fuel, or bio-based diesel. I’m talking about all of the above — biofuels.”

McGinn currently serves as president of the American Council on Renewable Energy, an organization which promotes the development of renewable energy technology including biofuels.

During his Navy service, McGinn commandeered the U.S. Navy’s Third Fleet which covers about 50 million square miles in the eastern and northern Pacific Ocean.

“It is absolutely critical that we recognize that there is a tremendous convergence — first, the need to expand our portfolio of energy to include biofuels,” McGinn said. “It is a national security issue and we need to address the energy, economic, and environmental aspects - local, regional, and global – with an expanded portfolio of energy with an increasing percentage of biofuels.”

McGinn shared several past and current domestic and international threats which could quickly reduce the reliability of U.S. petroleum imports. Iran could shut off oil transportation through the Strait of Hormuz due to current U.S. sanctions against the country.

Oil exports from Libya were temporarily severed during the Libyan revolution which impacted global energy markets. If the cutoff had lasted for weeks or months, the impact could have been staggering for the U.S. economy.

“We would look at the 2008 recession as if it was the good old days,” the vice-admiral said.

McGinn also pointed to the U.S. Gulf Coast and the interruption of oil extraction and gas products after Hurricane Katrina in 2005. A “son or daughter” of Katrina with a higher veracity could more directly hit the energy sector in the Gulf creating an even larger disaster.
