What are the differences or advantages of natural gas vehicles?
Natural gas vehicles tend to cost $4,000 to $8,000 more than gasoline-powered vehicles. Some natural gas vehicle owners have reported service lives 2 to 3 years longer than gasoline or diesel vehicles, as well as extended time between required maintenance. Natural gas is now cost-competitive with gasoline, and more recently, has been cheaper as a transportation fuel. Using natural gas as a transportation fuel also reduces our reliance on energy imports. Approximately 85 percent of the natural gas Americans use is produced domestically, and around 13 percent comes from Canada. This means that 98 percent of our natural gas supply comes from North America. This is a stark contrast to our petroleum supply, where over 60 percent is imported.
