Question

You have a number of 100MW oil-fired power plants. Supply a small island (population of 1 million, some industry, some military) with electrical power. The average (day and night) use of electrical power is 0.5 kW/hour per person.

1.How many power plants would you need?

2. Where would you place them?

3. How would you distribute the power?

4. Can you assure 24 hour electrical power availability? What do you have to add to assure 24 hr electrical service?

5. What are the advantages?

6. What are the disadvantages?

7. What are the costs? What are the enviromental effects?

8. Is that kind of power generation sustainable?

9. Do you have excess electric power to convert other energy uses, such as transportation, to electricity?

10. if you could choose to use nuclear power plant, oil-fired power plant, wind turbine generators, and or solar photovoltaic systems. Which would you prefer and why. Would you use more then one or all? Explain?

Explanation / Answer

1.How many power plants would you need?

ans) total power required by a person=24*0.5KW=12KW.

hence,total power required by island=10,000,000*12KW.=120MW.

--->power produced by one plant=100MW.

-->hence number of power plants required=120/100=1.2.

--->hence number of power plants=2.

2. Where would you place them?

--->well,there may be different ways to place the plants on the island.

---->one such way is to place them in two opposite corner of the island.

3. How would you distribute the power?

--->well,there are various ways to distribute the power.

--->one way is to supply power to half of island from one power plant,and other half of island by the other plant.

4. Can you assure 24 hour electrical power availability? What do you have to add to assure 24 hr electrical service?

--->24 hour electrical power availability cannot be assured.

--->ways to assure 24 hour availability is to create backup powerplant.

5. What are the advantages?

--->advantages:-

a)24 hour electicity.

b)no inconvenience in day to day work

c)more productivity.

d)better economy.

6. What are the disadvantages?

--->disadvantages:-

a)more cost.

b)the backup may remain useless or unused.

c)electricity loss.

7. What are the costs? What are the enviromental effects?

--->the cost in producing electricity.

--->cost in setting plant

environmental effects.

--->coal or fuel used to produce electricity lead to global warming.

---->depletion of resources.

8. Is that kind of power generation sustainable?

--->as long as electricity produced is efficiently distributed , power generation is sustainable.

9. Do you have excess electric power to convert other energy uses, such as transportation, to electricity?

-->yes,I have excess electric power to convert other energy uses, such as transportation, to electricity.

10. if you could choose to use nuclear power plant, oil-fired power plant, wind turbine generators, and or solar photovoltaic systems. Which would you prefer and why. Would you use more then one or all? Explain?

--->I would prefer solar photovoltaic systems because they are environment friendly.
