This video is from the Energy 101 video series. It explains the process for converting micro-algae into fuel and makes the case that algae-based biofuels hold enormous potential for helping reduce our dependence on imported oil.

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 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 sustainable strategies.

In this activity students make biodiesel from waste vegetable oil and develop a presentation based on their lab experience. Parts of the activity include creation of bio-diesel from clean vegetable oil, creation of bio-diesel from waste vegetable oil, chemical analysis of biodiesel, purification of biodiesel, and creation of soap from glycerin.

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 animation illustrates how heat energy from deep in Earth can be utilized to generate electricity at a large scale.

In this activity, students use Google Earth to investigate a variety of renewable energy sources and select sites within the United States that would be appropriate for projects based on those sources.

This video reviews the benefits and drawbacks associated with growing corn to make ethanol.

In this activity, students explore what types of energy resources exist in their state by examining a state map to identify the different energy sources in their state, including the state's renewable energy potential.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.
