In this activity, students use Google Earth to investigate a variety of renewable energy sources and select sites within the United States that would be appropriate for projects based on those sources.
This video is one of a series from the Switch Energy project. It reviews the environmental impacts of various energy resources including fossil fuels, nuclear, and renewables. CO2 emissions as a specific environmental impact are discussed.
This is a hands-on activity students design, build, and test. They compare the energy-generating capacities of vertical- and horizontal- axis wind turbine prototypes they have built as potential sources for power in a home.
