Lesson 3 Quiz Questions-Renewables

1)What does RPS stand for. This is a means of re-exposing you to one of the concepts covered.

2.            In standard electricity generation (by coal, natural gas, or nuclear) it is the high- temperature, high pressure steam turns the_______ directly that runs the ____________

3.            See this how a wind turbine works. (Note the gears turn a generator.) The Betz limit is [answer]% (whole number is fine).

4.            This is what type of thermal solar plant is this. [answer] (one word answer expected)

5.            This is a windmill.

6.            This is not a wind turbine! It is underwater, taking advantage of tidal flows. There is lots of energy even at low speeds because

a.            Water is dense

b.            The water is cold

c.             It works at night

 

d.            It works 24 hours a day, every day

7.            Electricity demand is always increasing

8.            This large solar plant is using which solar technology (one word answer beginning with “p”)? [answer]

9.            Ocean [answer] Energy Conversion can produce electricity where there is warm surface water and cold (deep) water.

10.          One of the problems with wind power (and some other renewables) is that it is not always available. What do we call this? Expecting a one word answer (a longish word starting with “I”) [answer]

11.          This is not a tidal storage location (on a lake with limited tidal variations). It is a (two word answer expected) [answer] location. (It is a special “hydroelectricity” case where electricity is used to move the water when electricity is cheap/abundant).

12.          The State of Pennsylvania encourages construction of wind farms via a tax rebate (through the end of 2019 and may be renewed).

13.          We can retire a 500 MW coal-fired power plant and replace it with a 250 (2 MW) wind turbines.

14.          This is an example of [answer] biomass. It is used to make handling, transportation, and use of biomass in a combustion system easier. The technical name is expected: Torr******.

15.          One of the few energy storage methods for electricity is known as (two word answer expected) [answer]. It is only available in a few locations but may well grow to aid with the challenge of incorporating renewable energy into the grid.

16.          We are currently retiring old coal-fired power plant. Thus we need to replace that capacity and add more due to the electricity demand growth.

17.          Why is the percentage of electricity from renewable hydroelectricity falling in the United States?

a.            Public opposition to dams because of safety concerns

b.            Droughts are now more common

c.             Demand for electricity has grown significantly

d.            Dams have been removed
