POWER PLANTS 1. Electric __________________, the flow of charged ___________________________ 2. What did the Greeks discover they could generate by rubbing amber? ___________________ ___________________________ 3. What are some of the “fuels” that are used to produce electricity? _________________________ ______________________________________________ 4. In 1879, Thomas Edison created the first incandescent lamp with a high ___________________ _________________ that glowed when heated by a low _______________________ 5. The major disadvantage to __________________________ power plants at the time, was that you could not transmit _____________________________ very far without losing a tremendous amount of the __________________________________. 6. Westinghouse put his company to work at perfecting a system using _____________________ __________________________ 7. Alternating current flows in ________________________________ which propagate more easily and with less __________________________ in transmission wire. 8. The beauty of alternating current is that you can generate it at a very high __________________ and then step it down to any voltage you need. 9. What “won the day” for alternating current? _________________________________________ 10. To what part of the plant were they building the tunnel to divert the river? _________________ 11. The turbines were essentially ___________________________________ that could be driven by the _______________________ of Niagara’s ______________________________. 12. What were the two components inside the generator that produced electricity? ________________________________________________________________ 13. What were the devices used to increase voltage so that electrical current could travel long distances? ________________________________ 14. Inside a transformer, an electric charge passes thru one _________________________________ inducing a higher or lower _________________________ in another separate coil. ____________________________ multiply at the ratio of the ________________________ __________________ in the primary coil to the _____________________________________ in the secondary coil. 15. Why were transformers needed? To increase the ______________________________________ to be able to _______________________________ longer distances. 16. What did greater voltages (pressure of electrons) allow? ________________________________ 17. What is the job of the transmission substation? ___________________________________ ___________________________________ 18. What is the term used to describe the process that a transformer does to DECREASE VOLTAGE? _________________________________ 19. To what voltage does a transformer “step down” the power to feed a house? ________________ 20. How long does it take the Bowen power plant to produce enough electricity for one house for a whole year? __________________________________________ 21. What 2 types of power plants generate most of the electricity in the U.S.? __________________ _____________________________________ 22. The way you generate electricity is that you take ______________ and you boil it and create _________________ and pressurize it, then you put it through a _________________________, which is a simple ___________ which turns, and then turns a ___________________________. 23. In what way has electricity production improved? It has become more _____________________ 24. The term used to describe “Demand” for electricity is __________________________ 25. What time is maximum “peak” load? _______________________ why? ______________ ____________________________________________ 26. How much coal is needed per day to supply the Base Load (24 hour) plant? ________________ 27. What is the coal used for? ________________________________________________________ _____________________________________________________________________________ 28. What is done with the steam after it is created? _______________________________________ 29. *****Do you think that the water is returned to the river at the same temperature that it was when it was pulled into the plant to cool the steam? ________________________________ 30. The Dahlberg plant uses _______________________________ instead of coal and creates _______________________ instead of steam to create electricity. Is it as efficient? __________ 31. Today, the energy market and the demand for ________________________________________ power have created a demand for _____________________________ 32. What types of power plants allowed for widespread electrical distribution? _________________ 33. Fission is the process in which natural ____________________ that are radioactive in nature, like ____________________ are bombarded with ________________________ and are _______________ into other elements, and when they are split, they release _________________________. 34. Uranium has the natural ability to _________________ which means the nucleus of the atom can _______________________________ releasing _____________ and _________________ which will create a _____________________________________. 35. What does the electrical generator do (in a nuclear power plant and in all the other power plants)? ______________________________________________________________________ 36. How long can the fuel last in a nuclear power plant? ________________________________ 37. What is the most significant nuclear power plant accident in the U.S.? _____________________ 38. What is one environmental “pro” to nuclear power? ____________________________________ 39. What is the biggest downfall to nuclear power? _______________________________________ 40. What is the biggest problem with energy consumption in our country? ____________________ ___________________________________________ 41. What are some of the environmental IMPLICATIONS (problems) with electricity production? ______________________________________________________________________________ 42. What are some of the problems with geothermal power? ________________________________ 43. Wind turbines are driven by the power of _______________ which drive the ________________ and produce ______________________________ 44. Limitations of wind power: _______________________________________________________ 45. The most futuristic of technologies, _______________________ combines 2 light atomic _____________ to form a single _________________________________________. This generates heat levels similar to the ____________ and releases unthinkable amounts of ________________ 46. What is the biggest debate with Solar Power? ________________________________ and the biggest drawback? ______________________________________________________________ 47. What is the future of solar power? _________________________________________________ 48. Solar Power makes ________________________ and ___________________________ sense. 49. What is the most environmentally benign method of making electricity? ___________________ 50. The future of energy production will be based on (choose one) renewables or nonrenewables because nonrenewables are _____________________ resources and will not be here indefinitely.
