This interactive visualization provides information in text, graphic, and video format about renewable energy technologies. Resource in the Student's Guide to Global Climate Change, part of EPA Climate Change Division.

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 as a 2-part activity in which students study the properties of CO2 in a lab and then use web resources to research different types of carbon capture. A video lecture accompanies the activity.
