Run cars on green electricity, not natural gas

Monday, November 24, 2008

From an analysis of natural gas for vehicle fuel by Jonathan G. Dorn posted on Earth Island Institute:

On economics, driving with electricity is far cheaper than driving with gasoline or natural gas. The average new U.S. car can travel roughly 30 miles on a gallon of gasoline, which cost $3.91 in July 2008 (the latest date for which comparable price data for natural gas is available). Traveling the same distance with natural gas cost around $2.51, while with electricity, using the existing electrical generation mix, it cost around 73¢. . . .

Just like oil, natural gas is a finite, nonrenewable resource. This means that switching to a fleet of NGVs would be at best a short-term fix. As natural gas becomes more difficult to obtain and more costly, a fleet of NGVs and the 20,000 or so natural gas refueling stations that would be required to support them would simply be abandoned. . . .

Choosing natural gas to power our vehicles would send the United States down the same expensive and inefficient path that created our addiction to foreign oil and our dependence on a resource that will ultimately run out. Choosing green electricity can take us in a new direction—one that leads to improved energy security and a stabilizing climate.
