In this activity, students learn about the pros and cons of co-firing woody biomass fuels with coal to produce electricity.

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.

In this activity, students conduct a life cycle assessment of energy used and produced in ethanol production, and a life cycle assessment of carbon dioxide used and produced in ethanol production.

This Flash animation describes how hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.

This lesson focuses on the importance of ocean exploration as a way to learn how to capture, control, and distribute renewable ocean energy resources. Students begin by identifying ways the ocean can generate energy and then research one ocean energy source using the Internet. Finally, students build a Micro-Hydro Electric Generator.

This video from the U.S. National Academies summarizes the energy challenges the United States faces, the technological challenges, and the need for behavior and policy changes required to meet the challenge.

This visualization includes a series of flow charts showing the relative size of primary energy resources and end uses in the United States for the years 2008-2012.

In this activity, students will determine the environmental effects of existing cars and a fleet consisting of their dream cars. They compute how many tons of heat-trapping gases are produced each year, how much it costs to fuel the cars, and related information. Then, students research and prepare a report about greener transportation choices.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

An activity focusing on black carbon. This activity explores the impacts of the use of wood, dung, and charcoal for fuel, all which generate black carbon, in developing countries.
