  •  Illustration of an energy source on a grid. Caption: and will power more than 650 homes.

    There’s a new renewable energy player in town, and it’s about to make waves in the industry. Despite its massive potential as a source for renewable energy, the ocean is unlikely to contribute meaningfully to electricity supplies without dramatic, innovation-driven reductions in the cost of energy conversion. That’s where engineers Balky Nair, Rahul Shendure, and Tim Mundon come in with their company, Oscilla Power. With support from the National Science Foundation, they’re developing a utility-scale wave energy harvester called the Triton. This technology shows promise as a means for delivering utility-scale electric power to the grid at a price that is competitive with conventional fossil or renewable technologies.

  • People working in an open area with debris covered ground and cattle grazing in the debris. Caption: Basic amenities like energy are scarce.

    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.

  • An industrial plant with multiple smokestacks emitting pollutants. Spanish captions.

    Energy has been essential for the development of human activities from the Industrial Revolution to present day. Over the course of history, human consumption of energy has increased significantly. Currently, society depends largely on nonrenewable energies that come from fossil fuels. However, the increase in greenhouse gas emissions has highlighted the need to change from fossil fuels to renewable energy sources that reduce environmental contamination. Many industries are committing to the development of alternative energy sources that don’t contribute to global warming. Chapter 9 of Air: Climate Change Series.

  • Tubing winding back and forth in front of a heat source heats cool water. Caption: which in turn drives a generator and results in energy.

    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.

  • Waves striking a man-made jetty of rock. Caption: could help solve the world's energy problems.

    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.

  • Person in a hard hat looking at a pressure gauge attached to industrial pipes. Caption: You can't build a plant just anywhere.

    Geothermal energy is one of the oldest renewable resources used by humans. It has been used since the ancient Roman times as a heat source. Recently, it has been harnessed and used as a source of power. Explains a few different ways that geothermal power plants operate. Discusses how experts are working to fine-tune the process and make the power plants more affordable and useful across the country.

    Rolling sand dunes with powerlines in the foreground. Caption: Beneath these dunes lies 65% of all known oil reserves.

    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 sun seen closely enough to show the light and dark pattern of the surface. Caption: Their mission: put the heat of the sun to work,

    More energy from the sun hits the Earth in one hour than is consumed on the planet in a whole year. Caltech chemical engineer Sossina Haile and University of Minnesota mechanical engineer Jane Davidson are working to expand the nation’s renewable energy storage capacity. Their mission is to put the heat of the sun to work creating renewable fuels from sources that don’t need to be drilled out of the ground.

  • Person handling a partially ripe strawberry still on the vine. Caption: "What can we plant? What's the rotation strategy?"

    The Pajaro Valley, in the Monterey Bay area of California, is ideally suited for agriculture. In fact, the Pajaro Valley and the nearby Salinas Valley produce nearly half of the strawberries grown in the United States yearly. But, the water source for the valley is a confined underground aquifer that is slowly being depleted. In January of 2011, the American Institute of Mathematics held a Sustainability Problems workshop with the goal of bringing together mathematicians and industry representatives to work on a variety of sustainability problems, including renewable energy, air quality, water management, and other environmental issues.

  • Newer model SUV. Caption: you need the conventional engine to drive the power train,

    Using only gasoline to power cars back in 1905 was cheaper and easier, so the hybrid car was forgotten-until recently. The modern hybrid car has two distinct power sources working together to make it run: gas and electric power. Since the fuel widely used now is a non-renewable resource and becoming increasingly less affordable, the hybrid car is making a comeback. The benefit of the hybrid is that instead of running on gas, it uses non-polluting electric power when possible. Also, it helps cut pollution and saves drivers money at the gas pump.

  • Gasoline pump labelled "Ethanol" with two gas pumps. Caption: is actually a blend of ethanol and unleaded gasoline.

    With today's high fuel costs, it is time to start looking beyond petroleum and into renewable resources to power vehicles. Ethanol is a clean-burning fuel derived from plants, primarily corn. It is combined with gasoline to produce a cleaner fuel that doesn't emit as many greenhouse gases as pure gasoline. Pure ethanol has not yet been approved to fuel vehicles, but it is the fuel of choice for racecars. By mixing gasoline with ethanol, fuel supply can be extended. Explores the production of ethanol and highlights the importance it holds in the "green power" movement.

  • Using Energy

    • Video
    Illustration of the sun sending heat into space and that heat hitting the Earth. Caption: So how is the sun able to heat the earth?

    Teaches caveman Zog that people use energy in one of two main ways: by moving heat from one place to another (conduction, convection, or radiation) or by transferring energy from one form to another by using an appliance, like a lamp or car. Appliances always waste some energy, and Zog learns why energy efficient appliances are the best choices people have today. As only a caveman can, Zog provides plenty of laughs along the way to finding clever and complete answers to elementary energy questions.
