## Presidents' Climate Commitment (Assignment Due Wed. 3/20/13)

Wittenberg University is one of hundreds of college institutions that have committed to reducing its' carbon footprint.

TASK 1: Our Commitment

1) (3 pt) Read through the website (especially the about tab) and summarize what Wittenberg has agreed to do to become more sustainable.

2) Explore the signatories: (1 pt) a) how many institutions have signed the President's Climate Commitment?

( 5pt) b) From the signatories, examine some (3-5) of the submitted Climate Action Plans. From the plans that you examined are any of the activities that lead to improved sustainability good fits for Wittenberg? Be specific (e.g. list a college, describe some of their sustainability activities and explain why you think they would be good fits for Wittenberg).

3) (1 pt) What building on campus is the most energy efficient? (This may require some investigation of our website, or talking with professors and other students).

TASK 2: Energy Audit

As part of our Climate Committment, Wittenberg University submitted a Greenhouse Gas (GHG) Report, an audit of our total energy use on campus.This effort was conducted by Dr. Andrew Scholl and Wittenberg students.

1) There are three scopes (categories) of emissions considered in the GHG Report; (1 pt) a) In our GHG report, which scope represents the bulk of our carbon emissions? ( 1 pt) b) What are the subcategories in this scope & which is the subcategory that represents the bulk of our total carbon emissions?

2) (2 pt) From the above question, why is it that replacing the purchase of coal generate electricity with renewable sources an excellent option for this class to explore.

3) The Green Energy Ohio website includes a calculator that shows the savings associated with solar panels.

(1 pt) a) Use the calculator for Dayton determine to the total annual (365 days) AC energy (kwh) produced by a m2 solar panel (in kilowatt hours per m2 per day (kwh/m2/day)). b) (1 pt) What is the associated annual reduction in CO2 emissions from one solar panel if 1 kwh = 0.0007 Metric tons of CO2 (From the EPA website: http://www.epa.gov/cleanenergy/energy-resources/calculator.html). (2 pt) c) Based on this conversion, and the total metric tons of CO2 associated with electricity purchase at Wittenberg, how many 1 m2 solar panels would Wittenberg need to completely replace its electricity generation? To make this calculation, you will need to first calculate the metric tons of CO2 saved annually by one m2 solar panel. You will divide the total metric tons of CO2 associated with electricity purchase by the metric tons of CO2 saved annually by one panel to determine the number of panels needed.
