  • A large bank of solar panels. Photovoltaic cells. Caption: Or on a smaller scale by using photovoltaic cells.

    Solar power is defined as the energy produced by converting sunlight into heat or electricity. It is one of the most abundant and affordable sources of energy available. However, it is difficult to harness (and even impractical) in some parts of the world, so it is important to explore the process of converting sunlight to power. Shows three primary ways to produce solar power on a large scale: solar power–generating plants, photovoltaic cells, and solar thermal heaters.

  • Glowing ball of the sun with heat visibly radiating off it. Caption: An inferno spewing energy, heat, and light.

    Our Sun is a nuclear reactor converting hydrogen to helium continuously. X-ray and telescopic images reveal the Sun's photosphere and chromosphere, sun spots, solar flares and winds, and prominences. Describes each and its impact on Earth. Covers some of the Sun's mysteries, and projects what will eventually happen to our closest star.

  • Closeup of a solar panel. Caption: and so "photovoltaic" combines light and electricity.

    Can people in remote rural areas who are far from electric generating plants get power for their lights and appliances? Solar cells make it possible. Mechanical and electrical engineers at the US Department of Energy's Sandia National Laboratories take viewers through the process of designing and installing solar cell panels in remote locations.

  • Solar eclipse. Caption: Birds roost, flowers close, and, like heralds, dogs bark.

    A total eclipse of the sun is the greatest spectacle in our solar system. Gives an in-depth explanation as time-lapse images capture the full impact of this event. Begins with a discussion of lunar eclipses before moving on to examine auroras. Explores the causes of auroras, and gives examples of two: the Aurora Borealis and the Aurora Australis.

  • An illustration of a galaxy.

    Discover what happens at the outer edges of the solar system where solar wind interacts with interstellar space. The Interstellar Boundary Explorer (IBEX) is a mission to study the boundary between the solar system and interstellar space. It collects data that shows the global structure and dynamic nature of the heliosphere.

  • Electrical meter box attached to the outside of a building. Caption: All the entries have to be zero-energy homes,

    The Solar Decathlon is an annual event where collegiate teams design, build, and operate solar-powered homes. In 2011, it was held on the Mall in Washington D.C. Twenty solar-powered homes were sprawled across the mall’s west end, transforming it from a park into something that resembled a quirky housing development.

  • Hillside covered in solar panels. Caption: collecting the sun's energy

    Arizona gets plenty of sunlight, and researchers there are working hard to turn that energy into electricity. At Arizona State University, graduate student Brad Brennan makes and tests new materials that will allow industry to build smaller, cheaper, flexible photovoltaic solar cells that can go almost anywhere.

  • Cartoon of three people and bird. The bird is holding a banana peel. Caption: Our solar power system is kaput!

    When the power mysteriously goes out at the new Radopolis skate park, the CyberSquad and Digit must find a way to turn it back on before a nighttime skateboarding extravaganza. Part of the "Cyberchase" series.

  • A diagram illustrates a solar eclipse. An object has its actual position behind the Sun. The line of sight of this object from the Earth is a curved line. But, the object it is observed at a different position from the Earth. This line of observation is a straight line. The angle between the two lines is labeled, proof.

    Find out how Albert Einstein used the totality phase of the 1919 solar eclipse to prove his theory of relativity, which predicts that large objects bend “space-time” towards themselves.

  • The moon directly in front of the sun. Caption: Seeing a solar eclipse can be an unforgettable experience.

    Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the solar eclipse. Part of the Science Video Vocab Series.

  • Circular cloud with a bright center against space. Caption: To understand comets, we return to the earliest solar system,

    Focuses on comets, those mostly unpredictable, wandering objects in the solar system. Uses time-lapse images while explaining a comet's tail and the meteors, or "falling stars," associated with it. Mentions Halley's and Hale-Bopp comets and international efforts to see these bodies more closely. Contains actual pictures of comets photographed by space probes.

  • People on a rooftop wearing hard hats with tools in their hands. One hard hat says "Solari" on the back. Caption: installing modules and arrays for large commercial sites

    Part of the "Green Careers" series. Details the entire range of jobs needed to make solar power a reality from research and development, design and marketing, and financial analysis to construction and project management. Engineers, analysts, and managers share how they work in this emerging green industry and how they found the opportunity to be part of the clean energy solution. Jobs profiled include the following: research and development engineer, design engineer, marketing manager, financial analyst, construction manager, and project manager.

  • Setting sun as seen through tall wild grasses. Caption: to harness the sun's energy to make renewable fuels.

    Solar panels are becoming a familiar site in communities across the United States, but what about solar fuels? A solar fuel is produced from sunlight through artificial photosynthesis, mimicking what Mother Nature has been doing for billions of years. Many chemists and chemical engineers are working to make solar fuels a viable option in the future. Part of the National Science Foundation Series “Science Nation.”

  • The planets of our solar system in a line. Caption: We'll begin with Mercury, the closest planet to the Sun.

    Satellite footage, telescopic photos, and animation are used to teach students about the many aspects of the solar system. Viewers are introduced to ancient astronomers, telescopes, observatories, and space exploration. Students will discover facts about planets, orbits, gravity, revolution, and rotation. The program also features discussions of the sun, comets, asteroids, and meteors. Part of the Real World Science series.

  • Solar panels on a roof top. Caption: But even now, they say solar energy is ready for prime time.

    Modern society is very much defined by its access to electricity. What if researchers could advance sustainable energy technologies to the point where everyone around the world had access to clean, cheap energy sources? Richard Smalley, 1996 Nobel Prize winning chemist, called it the greatest challenge facing the world in the 21st century and coined the phrase "terawatt challenge." Researchers at the Quantum Energy and Sustainable Solar Technologies (QESST) Center are hoping to meet much of the terawatt challenge with solar technology alone by vastly improving the performance of photovoltaic cells. Part of the National Science Foundation Series “Science Nation.”
