Clean Cities

NREL assists the U.S. Department of Energy's Clean Cities program in supporting local actions to reduce petroleum use in transportation by providing technical assistance, educational and outreach publications, and coordinator support.

Clean Cities is a national network of nearly 100 coalitions that bring together stakeholders in the public and private sectors to deploy alternative and renewable fuels, advanced vehicles, fuel economy improvements, idle-reduction measures, and new transportation technologies as they emerge.

Technical Assistance

NREL engineers and researchers provide hands-on technical assistance to help Clean Cities coalitions, stakeholders, manufacturers, and fuel providers overcome obstacles to deploying alternative fuels and advanced vehicles. This includes expertise and guidance on vehicle operations and safety, fueling station design and performance, operator training, project economics, stakeholder capabilities, and more.

Get answers to technical questions related to alternative fuels, advanced vehicles, and energy efficiency in transportation through the Clean Cities Technical Response Service phone and email hotline managed by NREL. Seasoned experts answer a wide variety of inquiries and identify relevant publications, data, and other sources of information.

Educational, Technical, and Outreach Publications

Browse a large library of Clean Cities publications, developed and maintained by NREL, including reports, handbooks, fact sheets, and other documents that provide information related to the deployment of alternative fuels and advanced vehicles. As new technologies emerge, NREL offers up-to-date analysis, guidance, and expertise to facilitate their adoption.

Coordinator Support

NREL provides technical expertise, training, tools, and information resources to the nearly 100 Clean Cities coordinators who lead local coalitions. In turn, coordinators disseminate this expertise in thousands of communities across the country, enabling stakeholders to capitalize on new market conditions and technologies.
