In this lab activity, students investigate how to prepare a biofuel source for conversion to a combustible product. The activity models how raw materials are refined to process liquid fuels.

This video segment, adapted from NOVA scienceNOW, addresses how new technology can help monitor and modernize the infrastructure of the U.S. power grid, which is ill-equipped to handle our increasing demand for electricity. Video provides a great overview of how electricity is generated and how the grid works.

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

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.

In this video, students explore the work of Jay Keasling, a biologist who is experimenting with ways to produce a cleaner-burning fuel from biological matter using genetically modified microorganisms.

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

This is a slideshow without audio about the effects of sea level rise on a Louisianan coastal community - the Isle de Jean Charles -- and focusing on the human impact of disappearing land.

This video features residents of Shishmaref, Alaska, plus environmental journalist Elizabeth Kolbert and scientist John Holdren, exploring the human impacts of global climate change.

This video segment examines ethanol, a cleaner-burning fuel alternative to gasoline, and the efforts to produce it more efficiently.
