heat homes
provide electricity
both of the above
5. On a wind turbine, the ______ is used to shut down the blades if wind speed gets too high.
anemometer
yaw drive
controller
6. Which part of a wind turbine keeps the generator facing the wind direction?
turbine
yaw drive
anemometer
7. Relying on windows and building materials to capture incoming solar radiation WITHOUT distributing that energy is called
photoelectric heating
passive solar heating
active solar heating
8. The biggest drawback to using hydrogen fuel is that hydrogen does not naturally exist in its elemental form, and must be extracted from something else.
True
False
10. Which of the following is a disadvantage of wind power?
low energy efficiency
increased air pollution
backup systems may be needed for times of low winds
4 = both of the above.
5 = If by controller you mean the control system (computer or PLC's) then that is the answer, neither of the others is correct
6 = The yaw drive, in conjuction with the wind vane.
7 = Passive solar heating
8 = False. Biggest drawback is that there is not distribution system for Hydrogen.
10 = Backup systems required.
r we doing something about global warming?
1. Learn about it -- start with this Web site and see the References
2. Sell the SUV and choose cleaner, more efficient vehicles -- and reduce your airline travel, which pollutes more per passenger than cars.
3. Use efficient appliances, replace light bulbs, insulate 4. Buy renewable energy, like wind and solar
5. Organize the neighborhood and town for energy efficiency
6. Use your vote and influence as a citizen to elect responsive leaders
7. Encourage efficient transportation in & between communities
8. Plant trees, expand open spaces
9. Reduce sprawl and the paving of the landscape
10. Build for efficiency and solar power
11. Support sustainable farming and forestry
12. Reduce global deforestation
13. Develop an efficient energy policy, moving away from fossil fuels
14. Export new energy technology that uses renewable energy sources
15. ....and Start doing these things today

This is a cycle that the earth has been through before. Human actions add to it but by a small percentage (not to say that we shouldn't clean up our act anyway).
Did you also know that scientisits have just discovered that global warming is also happening on Mars?
