**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:

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

**Total
Miles Driven**: Subtract you initial odometer
reading from the your final Odometer Reading

**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?)

- 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

- 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

- 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)

- What
is your annual mileage:

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

- your projected annual need for gasoline:

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

- 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/gallo**n = 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

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

**Total
Annual CO _{2} 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**
