Why are gas turbines more efficient at generating electricity than steam turbines?
A)Gas is combustible, but steam is not.
B)Electricity conducts better through the gas exhausts, which are ionized.
C)Water has a relatively high specific heat capacity.
D)Their hot combustion products provide more energy to turn the turbine.

Question

Quizplus · Accepted Answer

Gas turbines are more efficient at generating electricity than steam turbines because their hot combustion products provide more energy to turn the turbine. In contrast, steam turbines rely on the heat energy in steam, which has a relatively lower temperature, and thus less energy available to turn the turbine.
