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 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 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.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options projected out to 2100.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is a building strategy that can save operating costs for homeowners and businesses.

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 five short videos are an introduction to the pros and cons of energy issues, including cost, choices, efficiency, environmental impact, and scale. The videos are segments of a feature documentary entitled, Switch: Discover the Future of Energy.

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 suite of short video clips is part of a series produced by the Switch Energy project. There are several video segments that discuss different perspectives of biofuels as a renewable source of energy.
