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.

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

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.

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.

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.

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 activity is the first of five in the High Adventure Science Energy module and focuses on sources of electricity in the US by state as well as consumption in the US by sector and globally per capita.

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.

This video segment from the Earth Operators Manual summarizes how fossil fuels are made, provides a comparison of how long it takes to store energy in coal, oil and natural gas, and discusses how fast we're using them.

In this activity, students collect data and analyze the cost of using energy in their homes and investigate one method of reducing energy use. This activity provides educators and students with the means to connect 'energy use consequences' and 'climate change causes.' Through examining home energy use and calculating both pollution caused by the generation of electricity and potential savings, students can internalize these issues and share information with their families.
