This video from the U.S. National Academies summarizes the energy challenges the United States faces, including the technological challenges, and the need for changes in consumption and in energy policy.

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.

This set of flow charts illustrates energy sources and uses in 136 countries around the world. The data from 2007, but is still useful for comparing energy patterns in different countries. This is the first comprehensive package of worldwide, country-level energy flowcharts that has been produced.

These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.

Sankey (or Spaghetti) diagrams parse out the energy flow by state, based on 2008 data from the Dept. of Energy. These diagrams can help bring a local perspective to energy consumption. The estimates include rejected or lost energy but don't necessarily include losses at the ultimate user end that are due to lack of insulation.

This is a semester-long jigsaw project in which students work in teams to explore the effects of energy resource development on local water resources, economics, and society. Students are presented with a contemporary energy resource development issue being debated in their community. They research the water, geological, economic, and social impact of the project, and then either defend or support the development proposal.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

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 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.
