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.

This animated video outlines Earth's energy. The video presents a progression from identifying the different energy systems to the differences between external and internal energy sources and how that energy is cycled and used.

This visualization focuses on public acceptance of climate science. The set of interactive maps illustrates public opinion on a variety of climate beliefs, risk perceptions, and policy support. The data is from the Yale Project on Climate Communication.

This visualization is a map showing the global Climate Demography Vulnerability Index (CDVI) - areas of human population with the highest vulnerability to the impacts of climate change.

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 video is one of a series of videos produced by the Switch Energy project. It presents the pros and cons of wind power, such as where to build, affordability, efficiency, transmission.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.

This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.

This animation depicts real-time wind speed and direction at selected heights above Earth's surface, ocean surface currents, and ocean surface temperatures and anomalies.

These graphs show carbon dioxide measurements at the Mauna Loa Observatory, Hawaii. The graphs display recent measurements as well as historical long term measurements. The related website summarizes in graphs the recent monthly CO2, the full CO2 Record, the annual Mean CO2 Growth Rate, and gives links to detailed CO2 data for this location, which is one of the most important CO2 tracking sites in the world.
