This video highlights the benefits of electric vehicles, including improved fuel efficiency, reduced emissions, and lower maintenance costs.

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 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.

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

This video is a segment from the Switch Energy Project focusing on energy security. Switch Energy Project is a multi-pronged effort designed to build a balanced national understanding of energy.

Students investigate how much greenhouse gas (carbon dioxide and methane) their family releases into the atmosphere each year and relate it to climate change. To address this, students use the Environmental Protection Agency Personal Emissions Calculator to estimate their family's greenhouse gas emissions and to think about how their family could reduce those emissions.

This interactive visualization created by FRED (Free Energy Data), displays energy supply (by source) and demand (by use) for each state in the US from 1960 to 2010; forecasts through 2035 are available as well.

FRED is an open platform to help state and local governments, energy planners and policy-makers, private industry, and others to effectively visualize, analyze, and compare energy-use data to make better energy decisions and form sustainable strategies.

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 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.
