Procedure:
Electrical generation has different cost in different parts of the country. In the Pacific Northwest a high percent comes from hydroelectric facilities that were constructed many years ago and have come under increased scrutiny because of their environmental costs.

Ask students to research the mix of electrical generation in different parts of the USA along with the CO2 generated by the various methods of generation.
