Natural gas is used in many places to produce electricity. It is use in the manufacturing of ammonia fertilizers and it is used in many manufacturing processes as a source of heat energy.
I agree that we need to make better use of natural gas. Natural gas, as liquified natural gas and compressed natural gas has been used in some vehicles with success, but it has to be fleet vehicles at the time, because of the missing infrastructure.
We have an abundance of natural gas and more to be developed, gas hydrates deep in the ocean offer an almost unlimited supply of natural gas. Unfortunately the technology to recover this frozen gas has not been adequately developed.
Natural gas would be an excellent vehicle fuel. However, it is going to meet resistance from some because it is a fossil fuel. You will still have to drill wells, need pipelines and new storage facilities. However, those are issues that can be resolved if the country can ever come together on a consensus on what our next vehicle fuel source will be.
