Use of Natural Gas in Vehicles Climbs Slowly
Slowly but surely, the use of natural gas as a substitute for gasoline in our cars is climbing. The graph shows a 33% increase over the past seven years. however the trend may be about to accelerate. T. Boone Pickens' Clean Energy Fuels is having success building a "CNG Highway" across the country, aimed mostly at heavy-duty trucks. Recently the Energy Information Administration projected that LNG and CNG consumption in the transport sector will increase over the next 25 years, mostly by substitution in trucks, buses and rail freight. However, this would still natural gas displacing only 3 percent of our oil budget. We will probably never make any real progress until we start using liquid methanol and ethanol in regular passenger cars.
