Learn the history of the use of biofuels, and find out how this works to convert the energy stored in biological materials into electrical power.

This site provides information on renewable energy, including biomass resources, geothermal resources, solar resources, and wind resources.

In this unit students explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs and then they discuss how food webs can illustrate the health...

Biofuels can provide energy without the reliance on environmentally harmful fossils fuels, but scientists are still searching for a plentiful source. Craig A. Kohn demonstrates how cellulose, the naturally abundant tough walls of plant...

After completing research and field-work, students create a calendar with photographs, illustrations, and information about four different types of renewable energy: solar, wind, hydropower, and biomass.

Let this classic family of monsters guide you as you learn about energy. Interactive exercises, experiments, and demonstrations help to build knowledge and raise questions.

Students consider the impact and sustainability of use of different biofuels on the economy, the environment, and society. Students also learn about bioelectricity and how converting biomass to electricity may be the more efficient way...

Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will...

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.

This article, published by Scientific American (August 29, 2002), explores the successful manufacturing of hydrogen from a glucose solution derived from biomass. Such a fuel source, if proven practical, could easily power hydrogen...

Provides brief descriptions of the different methods used to generate electricity.
