The U.S. Department of Energy’s Office of Energy Efficiency & Renewable Energy created Clean Cities Tools, a group of resources consumers can use to calculate and inform themselves about ways to lower emissions, spend less money, and consume less petroleum. This set of tools allows consumers to compare different eco-friendly vehicles and systems; calculate the amount, cost, and impact of petroleum and greenhouse gas (GHG) emissions a fleet produces; locate alternative fueling stations; research how companies, fleets, and agencies are using alternative fuel; and much more. To view apps and mobile tools, please visit cleancities.energy.gov/m and fueleconomy.gov/m.
