U.S. Navy planning “Great Green Fleet”

The United States Navy is set to be both green and mean with the dawning of an new eco-friendly assault force that will mind its carbon footprint as it destroys its enemy. It is to launch “the Great Green Fleet”, a fighting force of ships, submarines and planes powered entirely by biofuels. The first group will be tested in 2012, and the navy plans for it to be operational by 2016.

The push for greener fighting forces runs across the Pentagon. The military accounts for nearly 80 per cent of the U.S. government's energy consumption and the two wars in Afghanistan and Iraq have made strategists acutely conscious of both the massive cost and serious security risks of the gas-guzzling ways of the past. By the time it arrives in the war zone, a gallon of gas can cost up to $400, according to a study by the Pew project on national security, energy and climate. The U.S. military is also anxious to cut down on fuel convoys to reduce troops' exposure to roadside bombs and other risks.

While a large proportion of Americans remain sceptical about global warming, the Pentagon does not. Its long-term strategic review earlier this year officially recognised global warming as a security threat. “The Department of Defence takes climate change seriously,” said Amanda Dory, Deputy Assistant Secretary of Defence for Strategy.

The Pentagon has committed to procuring 25 per cent of its electricity from renewable sources by 2025. It is also looking to convert its fighting machine to greener sources of fuel.

On Thursday, the navy will test an F/A-18 Super Hornet — the biggest gas-guzzler in the U.S. air fleet — powered by a 50-50 mix of jet fuel and camelina, an oil seed grown in Montana. The army is also investing in portable wind generators and working to take its huge base in Fort Irwin California off the public electricity grid in the next decade, using a 500MW solar panel array. The Marine Corps has a campaign aimed at reducing energy and water use over the next 10 years. — © Guardian Newspapers Limited, 2010
