Today, more than half the oil used for transportation in the United States is imported. Every year, we increase our dependence on imported oil - which increases the trade deficit, costs Americans their jobs and undermines our national security. As political situations in foreign countries evolve, American government, citizens and business owners are becoming more and more concerned about energy security.
Gasoline and diesel prices continue to rise. Fleet operators and citizens alike are feeling the pinch and are looking for ways to reduce fuel costs.
On the air quality front, vehicle emissions are the single largest contributor to air pollution in Las Vegas, making our air less healthy to breathe and increasing our health care costs. The significant growth population in the Las Vegas Valley, along with increased traveling, makes the problem of air pollution one that is difficult to correct.
For all these reasons, the time is right to transition to alternative transportation fuels that are cleaner, domestically produced and less expensive - fuels like biodiesel, electricity, ethanol, hydrogen, methanol, natural gas and propane. These fuels provide many advantages, including:
- They provide environmental and air quality advantages compared to other fuels.
- They can give economic advantages over other fuels.
- They allow compliance with federal and local laws and regulations requiring the use of alternative fuels.
- They promote national energy security.
Alternative fuels are part of the solution to many of our nation's -and our community's- problems. Using them helps improve the environment, keeps our economy strong and ensures that our energy supply is secure.
GREET Fleet Footprint Calculator - The Department of Energy's Clean Cities Program has enlisted the expertise of Argonne to assist in measuring the petroleum displacement and greenhouse gas (GHG) emissions of medium- and heavy-duty vehicles and off-road equipment. Argonne has developed the GREET Fleet Footprint Calculator for Clean Cities stakeholders to estimate these values using simple spreadsheet inputs.
The basis of this calculator is Argonne's Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) fuel-cycle model which is used to generate necessary petroleum use and GHG emission co-efficients of key fuel production pathways and combustion fuel types.
