Based on the latest figures from the U.S. Department of Energy’s Energy Information Administration (EIA),
the U.S. imported 65 percent of its oil, or 386 million barrels in March 2009, sending approximately $18 billion, or $403,226
per minute, overseas to foreign governments.
Reduced Emissions
Both Propane and Compressed Natural Gas (CNG) can significantly
reduce emissions versus gasoline.
