The 8-Step Action Plan Lesson 4 <ul><li>Awareness  </li></ul><ul><li>Issues </li></ul>
6 forms of energy A story…
The sun was out… (Nuclear)
And shining on the earth. (Radiant)
It was such a nice, sunny day, some people were out playing a game of catch… (Mechanical)
When the sun’s rays hit the people, they got hot.   (Thermal)
It wasn’t only the people enjoying the sunny day. The plants used the sun’s radiant energy to make food for themselves.   ...
But before long, the clouds covered the sun and a thunderstorm rolled in. (Electrical)
The End (Electrical) (Chemical) (Thermal) (Mechanical) (Radiant) (Nuclear)
Coal Chain A review…
now try to turn it into a  Wind Chain
what is wind?
wind: Wind is air in motion.  But what causes it to move?
Wind is produced by the uneven heating of the earth’s surface by energy from the sun.
 
how do we measure the wind? Wind Vane Anemometer
How do we use that information?
 
Amount of  energy produced   depends on   size of the turbine   and the   speed of wind
 
 
 
 
The  blades   of a wind turbine have the  most important job   of any wind turbine component – they must  capture the wind...

  3. 3. 6 forms of energy A story…
  4. 4. The sun was out… (Nuclear)
  5. 5. And shining on the earth. (Radiant)
  6. 6. It was such a nice, sunny day, some people were out playing a game of catch… (Mechanical)
  7. 7. When the sun’s rays hit the people, they got hot. (Thermal)
  8. 8. It wasn’t only the people enjoying the sunny day. The plants used the sun’s radiant energy to make food for themselves. (Chemical)
  9. 9. But before long, the clouds covered the sun and a thunderstorm rolled in. (Electrical)
  10. 10. The End (Electrical) (Chemical) (Thermal) (Mechanical) (Radiant) (Nuclear)
  11. 11. Coal Chain A review…
  12. 12. now try to turn it into a Wind Chain
  13. 13. what is wind?
  14. 14. wind: Wind is air in motion. But what causes it to move?
  15. 15. Wind is produced by the uneven heating of the earth’s surface by energy from the sun.
  16. 17. how do we measure the wind? Wind Vane Anemometer
  17. 18. How do we use that information?
  18. 20. Amount of energy produced depends on size of the turbine and the speed of wind
  19. 25. The blades of a wind turbine have the most important job of any wind turbine component – they must capture the wind and turn it into usable mechanical energy .
