2. Definition of Research Question What are the current energy consumption and CO 2 emission level for the 50 states? What can we say about the relationship between energy consumption and CO 2 emission? How can population influence the energy consumption and CO 2 emission level? What are the current energy consumption and CO 2 emission level for the 50 states? What can we say about the relationship between energy consumption and CO 2 emission? How can population influence the energy consumption and CO 2 emission level?

3. Definition of Objectives Two maps will display the total energy consumption and CO2 emission Another two will represent energy consumption per capita and CO 2 emission per capita 4 ArcGIS map products

4. Documentation of resources  Basemap  US POP 2010  CO 2 emission data 2010  Energy Consumption data 2010  Basemap  US POP 2010  CO 2 emission data 2010  Energy Consumption data 2010

5. Data Manipulation, Use of GIS tools Add field: Field Calculator:

6. Methodology

7. Results Total CO 2 Emission Total Energy Consumption CO 2 Emission per CapitaEnergy Consumption per Capita

8. Answers to Identified Questions o Energy consumption can make a great contribution to CO 2 emission. o High total CO 2 emission does not necessarily indicate a high CO 2 emission per capita. o There are differences between coastal states and inland states.

9. Limitation and Next Step Simple More Climate Variables More Thoroughly Developed
