Once you have selected the appliance, survey 10 or more rooms to get a statistical sampling of the appliance frequency on campus.  Determine the energy consumed by the appliance over the course of the academic year and compute the total energy consumed by all students using the appliance.  Put your data in the table above and provide the details on your appliance and your calculations below.  This assignment is only submitted on this page.

Homework Assignment 3:  The Hybrid Car (due 2/21/2008)

    Using the US DOE Hybrid vehicle cost calculator, compare the lifetime cost of running a hybrid vehicle versus a conventional vehicle of the same size.   Each group of four students should select a different vehicle size class.   Use current fuel prices, a 10 year vehicle lifetime, and an annual millage of 15,000 miles.   Thy hybrid vehicles will save gasoline and, therefore, reduce carbon dioxide emissions.  How much would it cost to purchase carbon credits to offset the increased gasoline consumption of a conventional powered car?  How would purchasing carbon credits change the economics of running a hybrid versus a conventional car?  Please show your work and provide details on your calculations.
