this country has never adopted an energy policy that is why South America and Europe have 1,000% more natural gas vehicles than the U.S.
In Latin America they convert cars from gas to natural gas for less than $1,000. In the U.S. the EPA requires conversions that cost $7500 on up. There is no policy in this country. The major oil producers, the top 5 still get tax breaks when they make 25% profit on each dollar of revenue.
