Question

Suppose that Linfield’s energy all came from hydroelectric power (in fact, most of it does). How large of a reservoir would be needed to supply Linfield College with electricity for one year? Make an estimate. State your assumptions clearly. [Hints and useful info: Linfield used 8.7 million kWh (8.7x106 kWh) in the 2009 fiscal year. A kWh is a common unit of electrical energy, where 1 kWh = 3.61x106 J = 2.65 x 106 ft-lb. Make reasonable estimate for the elevation, reservoir depth etc., perhaps following problem 4.]
