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 set of six interactive slides showcases how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, antireflective coating, and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight.

This simplified animation of a geothermal power plant from the U.S. Department of Energy illustrates commonalities with traditional power-generating stations. While there are many types of geothermal power plants, this animation shows a generic plant.

This series of informative graphics provide a regional overview of US energy resources.

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.

In this video from Young Voices for the Planet, four middle-school girls (The Green Team) talk about their efforts to work with their peers to reduce the carbon footprint of their school and how they made the school more energy efficient.

This animation presents the characteristics of wind power as a source of clean energy. The viewer may examine how a wind turbine works by pausing and clicking on its components. They include a gear box, rotor, high-speed shaft, generator, wind vane, yaw drive, yaw motor, anemometer, controller, tower, and brake.

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