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 form sustainable strategies.

This activity introduces students to the process of converting sunlight into electricity through the use of photovoltaics (solar cells). Students complete a reading passage with questions and an inquiry lab using small photovoltaic cells.

This is a hands-on inquiry activity using zip-lock plastic bags that allows students to observe the process of fermentation and the challenge of producing ethanol from cellulosic sources. Students are asked to predict outcomes and check their observations with their predictions. Teachers can easily adapt to materials and specific classroom issues.

Students go through the design process and the scientific process to test the effect of blade design on power output. There is an optional extension to use the data to create an optimal set of wind turbine blades.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

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.

This video segment is adapted from Building Big, a PBS series hosted by David Macaulay. It explores Hoover Dam's hydroelectric capabilities by explaining how it is able to harness the potential energy stored in the reservoir and convert it to electricity. It also discusses environmental impacts of the dam and others like it.

This is a hands-on activity students design, build, and test. They compare the energy-generating capacities of vertical- and horizontal- axis wind turbine prototypes they have built as potential sources for power in a home.

This video provides an overview of the research of the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) on converting biomass to liquid fuels.

This video addresses the importance of efficiency in providing power to an increasingly large global population.
