In Energy Resources: Use & Conservation, students learn that we can harvest the power of nature from a variety of sources all around us: the Sun, wind, and water; the atom; energy stored in fossil fuels; and the very heat of the planet itself!

They discover what life was like before people learned to harness electrical energy and how energy-rich fossil fuels like coal, oil, and natural gas helped fire the Industrial Revolution. They learn why these powerful energy resources are nonrenewable and in jeopardy of being used up as global energy consumption continues to rise.

Students are encouraged to play an active role in energy conservation and harness energy from the Sun by creating their own solar-powered oven. Part of the multivolume Energy in Action Video Series. Teacher’s guide included.
