Energy Solutions?

Can we make a better environment by using more different sources of energy? Trucks and cars using natural gas reduce some local air pollution so they have been used in cities where they have natural gas pipelines. The system works by attaching a compressor to the gas line and pumping up a tank in the vehicle. The gas comes from fields that use fracking and pumped all around the country. The road tax is avoided because no one is collecting road tax at the compressor. This in the end, charges those not using natural gas for the road use and environmental damage done by the corporations and users of natural gas for vehicles.
