1. Fuel our Future Now!!! Fuel Efficiency

2. What is Fuel Efficiency? Efficient : performing or functioning in the best way with the least waste of time and/or effort Fuel efficiency : using the least amount of fuel to travel the greatest distance

3. Why is fuel efficiency important? Saves money Reduces climate change Reduces dependency on oil/fossil fuels Increases energy sustainability Visit: http://www.fueleconomy.gov/feg/why.shtml

4. What effects fuel efficiency? Weight or mass of a vehicle Engine design Vehicle design Vehicle maintenance (tires, air filters, oil changes)

5. Today’s Vehicles Most common fossil fuel engines are NOT very efficient Only about 15% of energy from fuel (gas in the tank) moves the vehicle or runs accessories (heat, air, radio) The rest is lost to heat and exhaust

6. Today’s Vehicles What good do they do? Get us where we need to go Transports goods Makes things happen faster What problems do they cause? Accidents Pollution

8. How to calculate fuel efficiency: Example: 15 gallons of gas in a tank 450 miles driven without refueling How many miles did each gallon of gas take the car? 450/15= 30 miles per gallon

9. Calculating fuel efficiency: Take a road trip to New York!!! About 600 miles from Dearborn, MI to New York, NY 30 miles per gallon 15 gallon tank $2.65 per gallon

10. Cost of driving to New York!!! 30 miles traveled on one gallon X 15 gallons in the tank 450 miles on one tank of gas 600 total miles -450 miles on one tank of gas 150 miles left to travel 15 x $2.65= $39.75 cost for one tank of gas 150 miles left to travel 30 miles traveled on one gallon = 5 gallons 5 gallons X $2.65 $13.25 cost of a partial tank 13.25 +39.75 $53.00 one way $106 round trip
