The project will consist of 200 wind turbines, each with a capacity of 4 megawatts (mw). each turbine costs
$1.2 million to build. electrical demand in the area to be served by the project is expected to be 2.0 x 100 mwh
per year.
(d) calculate how much electricity (in mwh) the wind project needs to generate per year in order to provide
80% of the annual electrical demand in the service area. show all work.
(e) customers in the service area pay $0.20/kwh for electricity. calculate how much revenue will be produced
if the wind turbines provide 80% of the annual electrical demand in the service area. show all work.
(f) assuming all turbines are operating, calculate how many hours the wind turbines must operate to provide
80% of the annual electrical demand in the service area. show all work.

1) earth's crust is made up of relatively rigid plates that ride atop earth's hot, semiliquid mantle. (2) the plates are called tectonic because they're in constant motion. (3) they can move because earth's mantle is a very hot and semiliquid fluid called magma. (4) volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) therefore, we often find volcanoes and earthquakes along plate boundaries. (7) plates may also collide. (8) when that happens, mountain ranges are formed. (9) for example, the collision of the plate carrying the indian subcontinent created the himalayan mountains when it collided with the asian plate. 2. which sentence in this passage introduces a new topic that might begin a new paragraph? a. sentence 5 b. sentence 4 c. sentence 7 d. sentence 6
