On the windswept tarmac of the former Alameda Naval Air Station, an inventive group of scientists and engineers are test-flying a kite-like tethered wing that may someday help revolutionize clean energy. Students explore the potential of wind energy and new airborne wind turbines designed to harness the stronger and more consistent winds found at higher altitudes.

Wyoming has long been known as an energy exporter, from oil to natural gas to coal. The state is now booming with two other resources: wind energy and qualified technicians trained to build, install, and service the growth in wind turbine technology. With National Science Foundation funding, Laramie County Community College in Wyoming is becoming a national leader in training.
Kathryn Johnson, an electrical engineer at the Colorado School of Mines, studies large utility-scale wind turbines. Kathryn’s research aims to make the turbines more efficient in order to capture as much of the wind’s energy as possible. Viewers also visit NSF’s National Center for Atmospheric Research, where scientists are working with local utility companies to create an advanced wind energy prediction system. Using data from sensors mounted on each turbine, the system generates a forecast specific to each turbine on a wind farm. This helps the utility company provide as much energy as possible from clean sources.
Wind is a natural resource that is readily available and virtually everywhere. Humans have been harnessing the power of the wind for around 2,000 years. The Dutch made the windmill famous. Defines the process of turning the kinetic energy of the wind into electrical energy. Shows how the large wind turbines are built using a simplistic design and modern technology. Explores how the use of wind power is growing and becoming widely used throughout the world.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on how wind turbines convert kinetic energy from the wind into mechanical and electrical energy. Part of the Science Video Vocab series.
Access to affordable, sustainable energy supplies is a growing concern around the world. Looks at successful enterprises that are providing some renewable energy solutions. In Scotland, small-scale turbines put wind power within the reach of domestic users. In Sweden, the world's first train to be run solely on biogas has been developed. In Nepal, biogas stoves are improving the quality of life in many ways. And in India, agricultural-plant waste is being turned into solid fuel briquettes for use in industrial stoves and boilers, while a solar-energy company has developed environmentally friendly lighting technology that disadvantaged communities can afford.
Harnessing energy from the waves of the world’s oceans seems like the ultimate in renewable fuel. With funding from the National Science Foundation, Electrical engineer Annette von Jouanne is leading efforts to capture wave energy, by creating simple, powerful devices that can withstand heavy winds, monster waves, and corrosive salt water. Oregon State University research now underway is based on ocean buoy generators. As ocean swells hit the buoy, electrical coils inside move through a magnetic field, inducing a voltage, and creating electricity.
Professional remodeler Danny Lipford offers practical home improvement information to homeowners. Discusses products and ideas for saving money on energy bills: caulking, expandable foam sealant, weather stripping, thresholds, insulated socket sealers, attic and window insulation, water heater blankets, and compact fluorescent light bulbs. Looks at using a flexible wheelbarrow screen for sifting rocks from soil. Talks about Dremel cordless tools. Gives reasons why homeowners should use mulch.
Learning to incorporate a variety of eco-friendly energy sources into businesses and homes will make Earth a better place to live. Students explore photovoltaics, the design behind wind turbine technology and the creative processes behind vehicles in the American Solar Car Race. Zero energy houses of the future will use many of these technologies to produce more energy than they consume. Renewable energy technologies are important for the future of our planet.
Can the wind provide us with all of our power? Along with cutting-edge wind farms and new turbine designs, this production meets renegade inventor Doug Selsam as he builds the world's first flying turbine, a device that may just change our world.
Caveman Zog wonders where does energy come from. As a caveman living long ago he knows that light and heat energy can come from the sun or burning firewood. But now he travels through time to learn that in our world we have many other sources such as oil, coal, natural gas, geothermal, nuclear, falling water, wind, and solar cells, and how some of these are used in power plants to turn generators to make electricity.
Revolutionary technologies now make it possible to harness a completely renewable energy resource-the natural power of the sea. Explores ways that electric power can be drawn from tidal forces or from fluctuations in ocean currents. Highlights several innovations, including a tide-driven rotor off the coast of Cornwall in the United Kingdom, a multi-rotor locks system in the English Channel, an OTEC (i.e., ocean-thermal energy conversion plant) in southern Japan, and another OTEC facility in Hawaii. Commentary from the inventors, designers, and managers of these systems is included along with animation that illustrates how each mechanism works.
Did you know Oregon crab fishers lose their pots because they often encounter high winds and waves up to 40 feet? Join Joel on this adventurous quest as he boards a vessel to sail the Oregon coast in search of crab pots in an effort to help clean up the ocean. Part of the Curiosity Quest Series.
Environmental and science experts explore the enormous potential for clean, renewable energy. They also illustrate the connections among such issues as solar energy, wind energy, energy efficiency, green buildings, and global climate change. Viewers also learn specific action steps that viewers can take in their own lives to create a sustainable future.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The class learns about other forms of energy when their "Double-Trouble Wheel of Wonder" shorts out. They learn how to use water, solar energy, wind, and their own muscle power and are able to get the Ferris wheel to run.
Clearly shows the environmental impacts of both renewable and nonrenewable energy sources. Provides an overview of numerous renewable energy sources, how the energy is collected, and the pros and cons of renewable energy. Also explores what is happening around the globe with the introduction of wind farms, wave parks, and solar farms.
What is the best way to power the planet? Travel the globe with scholar Johan Norberg, from Morocco to Sweden and throughout the United States, as he explores the pros and cons of the eight main energy sources available to us: coal, oil, natural gas, nuclear, hydro, biomass, wind, and solar.
Host award-winning geoscientist, Richard Alley provides an eye-opening look at some of the world's most important case studies in smart energy. Alley travels to Spain and Morocco where large-scale solar farms and individual photovoltaic panels atop tents in the Sahara are beginning to bring the vast potential of the sun down to Earth. In Brazil, abundant natural resources are transformed into efficient, sustainable biofuel, making Brazil the only nation whose cars could keep running if all gasoline were to vanish. In Denmark, and West Texas, citizens have taken sustainability into their own hands by becoming stakeholders in wind turbines. And in China, he explores multiple sustainable energy technologies, including exclusive footage from GreenGen, the world's most advanced low-carbon emissions power generation plant. Part One Earth: The Operators’ Manual.
Scientific evidence may show that human activity, particularly over the past 100 years, has led to a buildup of what are known as "greenhouse gases," the most common of which is carbon dioxide, in the atmosphere. Energy use, particularly the burning of fossil fuels and the large-scale removal of vegetation from the earth's surface, are thought to be largely responsible for greenhouse gas buildup.
Suggests tips and ideas for conserving energy and water around the home. Touches on energy savers in the kitchen, for the water heater, and around windows. Covers recycling garbage and managing hazardous waste disposal.
