This site from the Human Genome Project of Oak Ridge National Laboratory (ORNL) provides facts and information about the use of biomass fuel and its impact on the carbon cycle.

A 34-page report examining renewable energy sources in use in Texas. It looks at how Texas compares with the rest of the world, the companies investing in the Texas energy industry, the Texas electricity grid, government initiatives,...

An interesting discussion of energy forestry, where a fast-growing species of tree or woody shrub is grown specifically to provide biomass or biofuel for heating or power generation. Explains some benefits and problems with this industry.

In this activity, students learn about the pros and cons of co-firing woody biomass fuels with coal to produce electricity.

A comprehensive source of information about energy in all its forms. Each type of energy is explained, along with information about its environmental impact, supported with graphs, charts, and other data. There is a twenty-question quiz...

Learn about the many different energy resources available from our Earth. Find out the pros and cons of each type: both renewable and nonrenewable.

Society is beginning to recognize the limited supply of fossil fuels. In this project, students will investigate alternative energy sources. Conservation of resources is discussed and while conservation is an important step, at some...

Students explore what kind and how much bio-mass can be produced in an area around your city or town. They figure how many gallons of fuel can be expected from one acre of crop land, and how much carbon can be sequestered in the local area.

Kids learn about renewable energy and how it can help the environment. Teach students about solar, wind, biomass, and geothermal energy.

Information on different forms of renewable energy with links for student projects, resources for teachers, and links to related resources.

Read 37 slides on energy flow and the nutrient cycle.

This site, which is provided for by the Penn State University, gives twenty one chapters of charts, graphs, and information on synthetic fuels.

Try this five question comprehension check over ecosystems and the ecological relationships within them.

This report was created by 7th and 8th grade students in Vergennes, Vermont, as part of a Learning expedition called "Reducing the Carbon Footprint." The building manager met with a team of approximately 40 students as they investigated...

An overview of renewable energy resources in Texas, aside from wind and solar energy. Covers hydropower, geothermal energy, and biomass.

Students form expert engineering teams working for the (fictional) alternative energy consulting firm, Greenewables, Inc. Each team specializes in a form of renewable energy used to generate electrical power: passive solar, solar...

Will using agrofuel offer a substantial alternative to using fossil fuel? With this experiment you can compare the amount of heat energy released by agrofuel and fossil fuel. The Science Buddies project ideas are set up consistently...
