WPSU (Penn State University broadcast station), Teachers' Domain

This animation presents the characteristics of wind power as a source of clean energy. The force of moving air generates electricity, by rotating blades around a rotor. The motion of the rotor turns a driveshaft that drives an electric generator.

Climate Literacy
About Teaching Climate Literacy

A combination of strategies is needed to reduce greenhouse gas emissions. The most immediate strategy is conservation of oil, gas, and coal, which we rely on as fuels for most of our transportation, heating, cooling, agriculture, and electricity. Short-term strategies involve switching from carbon-intensive to renewable energy sources, which also requires building new infrastructure for alternative energy sources. Long-term strategies involve innovative research and a fundamental change in the way humans use energy.

Benchmarks for Science Literacy

Energy from the sun (and the wind and water energy derived from it) is available indefinitely. Because the transfer of energy from these resources is weak and variable, systems are needed to collect and concentrate the energy.

Teaching Tips

  • Do an oral review of the parts of the wind generator with students after they view the animation.
  • Educator may want to turn sound off (which is loud and somewhat annoying) and narrate the video themselves.

About the Science

  • This animation presents the characteristics of wind power as a source of clean energy.
  • Claims about the growth of wind power as an energy source since 1990 may or may not be accurate.
  • The pro-wind perspective in this video presents only the positives of the wind industry.
  • Comments from expert scientist: The "Background Essay" and "Discussion Questions" are particularly interesting and useful. The interactive section does a fine job of describing all the essential parts of commercial wind turbines.

About the Pedagogy

  • A good background essay and discussion questions accompany the animation.
  • Learners can learn about the working parts of a wind generator by clicking on each component.
