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.

In this interactive simulation, students can explore global CO2 emissions displayed by different continents/countries and plotted based on the GDP. A map view is also accessible.

This suite of short video clips is part of a series produced by the Switch Energy project. There are several video segments that discuss different perspectives of biofuels as a renewable source of energy.

In this video segment from NOVA's Saved By the Sun hour-long video, students learn about photovoltaics and see how two families are using solar technologies in their homes. The video introduces the ideas of state incentives and net metering benefits.

This introductory video covers the basic facts about how to keep residential and commercial roofs cool and why it is important to reducing the heat island effect and conserving energy.

This animation presents the characteristics of wind power as a source of clean energy. The force of moving air generates electricity, by rotating blades around a rotor. The motion of the rotor turns a driveshaft that drives an electric generator.

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 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.

This video segment from What's Up in the Environment shares how an entire home can be constructed using green energy sources (solar and geothermal energy). Video is narrated by young boy whose father is the chief engineer on the project.

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