Access to information, policy initiatives, advice, and analysis on issues of energy efficiency and renewable energy, from the U.S. Department of Energy. Its network is responsible for tracking the technological, economic, and...

Gross. What is that in the toilet? But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair...

This tutorial explores how organisms use energy to grow.

This simulation can be used as a virtual lab for photosynthesis, cellular respiration, and primary productivity.

Through interactive learning exercises, students examine the different definitions of energy and how enzymes regulate how the energy is stored and used during cellular respiration. They also take a close look at photosynthesis to learn...

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

Students learn about how a device made with dye from a plant, specifically cherries, blackberries, raspberries and/or black currents, can be used to convert light energy into electrical energy. They do this by building their own organic...

This unit provides students the opportunity to explore methods engineers have devised for harnessing sunlight to generate power. Students will initially explore heat transfer and heat storage through the construction, testing, and...

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of "Conservation of...

Explains how photovoltaic systems work and how Texas homeowners are using them. Discusses how a homeowner can use solar energy and still be on the electricity grid system.

In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of...

Explains oxidative phosphorylation, which is the fourth step of cellular respiration, and produces the most of the energy in cellular respiration.

Learn how living things obtain and use energy.

Chapter 22 of a report on the energy industry in Texas. It looks at hydrogen as an energy source, its history, and uses. The economic impact of the hydrogen energy sector in Texas is described, the consumption of hydrogen, methods of...

Comprehensive overview of the use of hydrogen as a source of energy. Learn what it is, how it is produced, its uses, and much more.

An article reviewing how energy flows in a cell including metabolic pathways.

Explanation of biochemical processes in cells during metabolism. Focus is on the generation of ATP.

The advantages and disadvantages of hydrogen fuel cell technology as a source for energy production are outlined. There is still much to be done in research and development before this energy source can be marketed widely.

Information and analysis on hydrogen and fuel cells.

Find out about renewable energy resources using solar energy technologies. Learn about the use of photovoltaic cells and the capture of the sun's energy.

[Free Registration/Login Required] An informational text about solar cells being made of plastic. A question sheet is available to help students build skills in reading comprehension.

Young scholars will participate in a laboratory investigation that models the production of silicon. The activity investigates the sources, uses, properties, and importance in the fields of photovoltaics (solar cells/renewable energy) of...
