Types of Energy

Climate Watch: Unlocking the Grid | PBS LearningMediaToday we rely on electricity more than ever. In this video from QUEST produced by KQED, explore the challenges of harnessing renewable energy. Find statistics on how California's electrical grid works and a description of the proposed smart grid. Also, learn about the challenges facing the development of wind energy and other renewable energy resources.

Geothermal Energy: Harnessing the Power of the Earth | PBS LearningMediaGeothermal energy is a renewable energy source produced from the heat inside Earth. In this video from KQED, discover how it is produced and its limitations.

Storm-ravaged Bahamas rebuilding its power grid with emphasis on solar energyA tiny country in "Hurricane Alley" is trying to be an example to the world after Category 5 storms demolished parts of its electrical grid. Bill Whitaker reports on the Bahamas' adoption of solar energy.

A Never-Ending Supply | PBS LearningMediaIn this video from NOVA’s Energy Lab, learn about renewable energy sources and renewable energy technologies. A renewable source of energy is so plentiful that it can be considered limitless. Scientists and engineers are working on alternative energy technologies that make use of renewable energy sources (such as solar, geothermal, and tidal energy) and have less impact on the environment. The Sun is our greatest energy resource; solar technologies use its energy directly in the form of light or heat, while other technologies use its energy after it has been converted into another form. This video is available in both English and Spanish audio, along with corresponding closed captions.

Nature Works - To Make Clean Energy: Video | Nature Works Everywhere | PBS LearningMediaExplore where our energy comes from, and what makes certain types of energy renewable and sustainable. Unlike the nonrenewable energy sources that humans currently use (fossil fuels, coal and natural gas), solar and wind power can quickly replenish themselves and are usually available in a never-ending supply. But we can't just harness renewable energy anywhere—what makes a good environment for harnessing sustainable power? Find a lesson plan here to accompany this video.
