The State of Colorado has identified the use of cleaner transportation fuels as a priority to promote energy security, environmental stewardship, job creation, and low consumer costs. As part of that effort, the State has specifically identified natural gas as a viable, low-cost alternative to gasoline and diesel. The nation's energy future is improved with the use of natural gas because it is more affordable, better for the environment, and reduces dependence on foreign oil. The Colorado Energy Office (CEO) is seeking to develop an NGV implementation plan for the State. This study provides information that will assist CEO with cultivating that plan.
