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.

In this video clip from Earth: The Operators' Manual, host Richard Alley discusses China's efforts to develop clean energy technologies and to reduce CO2 in the atmosphere, by building coal plants using CO2 sequestration technology. (scroll down page for video)

In this activity, students construct a Global Warming Wheel Card, a hand-held tool that they can use to estimate their household's emissions of carbon dioxide and learn how they can reduce them. One side of the wheel illustrates how much carbon dioxide a household contributes to the atmosphere per year through activities such as driving a car, using energy in the home, and disposing of waste. The other side shows how changes in behavior can reduce personal emissions.

In this activity, students learn about the energy sources used by their local utility provider to generate electricity, and work in small groups to evaluate the sustainability of either a renewable or non-renewable energy source used to generate electricity.

This activity from the Department of Energy provides background information about solar ovens and instructions on building a simple model solar cooker.

This video segment highlights how the U.S. military is the single largest user of energy in the nation, but it is also trying to reduce its carbon bootprint. Scenes taped at Fort Irwin and Camp Pendleton show the Army and Marines experimenting with wind and solar in order to reduce the number of fuel convoys that are vulnerable to attack.

This interactive provides two scenarios for students to look at issues related to energy and climate change: from the perspective of either a family, or a monarch.

In this 'Energy Education for the 21st Century' design challenge, students construct and evaluate a solar-powered model car. Students utilize the design process and undergo review by their peers to select an optimal gear ratio and components for their car. As a culminating activity, students compete in a Solar Sprint race modeled after the National Renewable Energy Laboratory's Junior Solar Sprint competition.

This video segment explores whether, in principle, renewable energy resources could meet today's global energy needs of about 15.7 terawatts.

This activity focuses on applying analytic tools such as pie charts and bar graphs to gain a better understanding of practical energy use issues. It also provides experience with how different types of data collected affect the outcome of statistical visualization tools.
