On Monday, the U.S. Navy will officially announce the ships for its demonstration of the “Great Green Fleet” — an entire aircraft carrier strike group powered by biofuels and other eco-friendly energy sources. If a powerful congressional panel has its way, it could the last time the Navy ever uses biofuels to run its ships and jets.

In its report on next year’s Pentagon budget, the House Armed Services Committee banned the Defense Department from making or buying an alternative fuel that costs more than a “traditional fossil fuel.” It’s a standard that may be almost impossible to meet, energy experts believe; there’s almost no way the tiny, experimental biofuel industry can hope to compete on price with the massive, century-old fossil fuels business.

But if the measure becomes law, it would make it all-but-impossible for the Pentagon to buy the renewable fuels. It would likely scuttle one of the top priorities of Navy Secretary Ray Mabus. And it might very well suffocate the gasping biofuel industry, which was looking to the Pentagon to help it survive.
