With the average price of gas $3.49, some are looking for other ways to get to work and for alternatives, like compressed natural gas.

Putting 20 gallons in a compressed natural gas vehicle will cost you about $20 at this gas pump. But at a regular gas pump putting in 20 gallons of gas would be about $70.

Tom Sewell is very busy because of high gasoline prices. He converts gasoline vehicles to run on natural gas as well. He says power and mileage are the same when a truck like this one runs on natural gas and says that natural gas burns 90-percent cleaner than gasoline.

"They're that clean, there's no exhaust smell," he says.

He admits converting to natural gas is expensive - as much as $11,000, but the state gives a 50-percent tax credit to people who pay that price.

People like Andy Kmetz get tax credits also for buying and driving new CNG vehicles. His Honda cost $25,000 and he got state and federal tax credits.

"You take the federal tax credit of four thousand, and I think the state is around $3,500," he says. He drives to and from work every day and estimates he saves about $1,500 a year.

Kmetz says CNG is not an end-all solution to our dependence on foreign oil, but it is today's solution, and it's here now and ready to use.

There are some drawbacks. There are just 3 CNG fueling stations in Tulsa. And CNG tanks hold only 8 gallons.
