A Diesel Rebirth in the U.S.?

An article in today's Washington Post talks about how automakers in Detroit, Japan and the U.S. are set to take advantage of what they think will be a rebirth in the popularity of diesel engines in the United States due to the EPA passing new regulations this past Sunday "requiring refiners and fuel importers to reduce the sulfur content in diesel fuel by 97 percent." The new regulations should help to cut down pollution from diesel engines a great deal. And, according to Mark MacLeod, the director of special projects for Environmental Defense, the regulations are 'expected to prevent about 8,000 premature deaths each year, 1.5 million lost work days and 360,000 asthma attacks.'
