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 video describes how concentrating solar power (CSP) technologies reflect and collect solar energy to generate electricity. This video explains what CSP is, how it works, and focuses on parabolic troughs.

This short video shows how different biomass feedstocks are processed and refined into sustainable biofuels via biochemical and thermochemical processes.

This video, from the US Department of Energy, shows the basics of how a PV panel converts light radiated from the sun into usable power, whether on the electric grid or off, and without emissions or the use of fossil fuels.

This video provides a simple introduction to wind turbines and how they generate electricity.

Watch students as they conduct an energy audit on a home and gain hands-on experience for a career in the green energy industry, in this video adapted from ATETV.

Students use Google Earth to analyze oil consumption per capita in the US and around the world. Students then use spreadsheets to create graphs and calculate statistics regarding per capita energy use among various categories.

This activity is a learning game in which student teams are each assigned a different energy source. Working cooperatively, students use their reading, brainstorming, and organizational skills to hide the identity of their team's energy source while trying to guess which energy sources the other teams represent.

This feature, adapted from Interactive NOVA: "Earth," follows the path of energy as it is transferred via the food chain from one type of organism to another.

This video segment, adapted from NOVA, describes the energy flow in a coral reef, including its food web.

This classroom activity introduces students to energy flow through organisms, producers & photosynthesis, and consumers & respiration.

In this activity, students explore what types of energy resources exist in their state by examining a state map and data from the Energy Information Administration. Students identify the different energy sources in their state, including the state's renewable energy potential.

This online activity challenges students to design a renewable energy system for one of five different cities, each with different energy resource potential and budgets. Students can test their designs using real-time weather data in each city.

Data sets and graphs on energy production, use, dependency, and efficiency are compiled through following key World Development Indicators.

This activity involves student research on the Internet to create a PowerPoint presentation showing the various parts that make up a biome (abiotic & biotic factors).

This video is a segment from the Switch Energy Project focusing on energy security. Switch Energy Project is a multi-pronged effort designed to build a balanced national understanding of energy.

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 issue of the free online magazine, Beyond Penguins and Polar Bears, explores the Sun's role in warming Earth, the albedo (reflectivity) of Earth's diverse surfaces, and how the decline of Arctic sea ice is affecting Earth's energy balance. Science lessons introduce the concepts of solar energy, reflection, and absorption to elementary students. The issue also includes an overview of the natural resources and energy sources found in the polar regions as well as lessons that allow students to develop the concepts of natural resources, energy sources, and energy efficiency.

An activity focusing on black carbon. This activity explores the impacts of the use of black carbon generating wood, dung, and charcoal for fuel in developing countries.
