Energy Project: Gasoline Demand :

During the first weeks of class you need to fill your gasoline tank in your car. During course you will keep a record of all purchases of gasoline noting dates, price, amount, cost and odometer reading. Get receipts or keep a diary in your vehicle. Then transfer each purchase to a data page or in a spreadsheet.

During the last weeks, you fill your tank again and record the data. You will determine:

1. The Total Miles driven; the Total Gallons Used; the Total Cost; and the Total Days of the Project.

Total gallon Used: Sum all your Gallons Purchased, except do not include the gallons recorded in your initial fill-up (Why?)

Total Cost: Sum all your dollars spent during the project, except the initial fill-up. (Why?)

1. Then you will compute the average MPG and the average cost per mile for the gasoline.

MPG = Total Miles Driven divided by Total Gallons Used

Average Cost Per Mile = Total Dollars Spent divided by Total Mile Driven

1. You will also calculate your average daily mileage and average daily gallons of gasoline used:

Average daily Miles = Total Miles Driven divided by Total Days of the Project

Average Daily Gallons Used = Total Gallon Used divided by Total Days of the Project

1.  How many times did you exceed 75 miles in one day?

(You may not be able to answer this, but statistic say that the average U.S. driver averages 29 miles per day-and this can be skewed if you took a long trip during the project to see if you are average)

1. What is your annual mileage:

Annual Mileage = your daily average miles driven calculated above multiplied by 365 days

1.  your projected annual need for gasoline:

Annual Gasoline Demand: Your average Gallons Used multiplied by 365 days

1. What will be annual cost at \$2.00 per gallon; \$3.00 per gallon; \$3.50 per gallon; \$4.00 per gallon; \$4.50 per gallon; and \$5.00 per gallon.

Annual Cost @ \$2.00/gallon = Yearly Gasoline Demand(gallons) multiplied by \$2.00/gallon

Annual Cost @ \$3.00/gallon = Yearly Gasoline Demand(gallons) multiplied by \$3.00/gallon

Annual Cost @ \$3.50/gallon = Yearly Gasoline Demand(gallons) multiplied by \$3.50/gallon

Annual Cost @ \$4.00/gallon = Yearly Gasoline Demand(gallons) multiplied by \$4.00/gallon

Annual Cost @ \$4.50/gallon = Yearly Gasoline Demand(gallons) multiplied by \$4.50/gallon

Annual Cost @ \$5.00/gallon = Yearly Gasoline Demand(gallons) multiplied by \$5.00/gallon

1. Total Pounds of Carbon Dioxide released into the atmosphere by you every year.

Total Annual CO2 Released = Total Annual Gallons Used multiplied by 19 pounds/gallon

i. The instructor may add additional data for you to determine to complete this project.

These calculations should be done in a spreadsheet or typed in table format, but the spreadsheet may either be hand drawn on your data page or done on the computer.

You need to only fill the tank twice, at the beginning and at the end of the project. You will not use the first fill-up in your calculations, except odometer reading. Why?

If you do not drive or own a vehicle and can not get cooperation from your family, the instructor will assigned an alternate energy demand project
