Compared with the Efficiency of a Typical Steam- Electric Generating

question 7

Multiple Choice

Compared with the efficiency of a typical steam- electric generating plant, the efficiency of a typical hydro- electric generating plant is

• A) smaller, because only a small amount of the energy in the water behind a dam can be converted into electricity.
• B) about the same, because both are heat engines and so both have the large inefficiency implied by the second law of thermodynamics.
• C) greater because a hydro- electric plant is not a heat engine and so it does not have the large inefficiency implied by the second law of thermodynamics.
• D) smaller because a steam- electric converts thermal energy into non- thermal forms and the second law of thermodynamics implies that this is a highly efficient process.
• E) greater because a hydro- electric plant uses the sun as its source of energy, rather than hard- to- obtain fossil fuels.
