1.2.1.2 Efficiency and Cost

Theoretical maximum efficiency is (Twarm-Tcold)/Twarm
This is called the Carnot Efficiency
Theoretical MAXIMUM 7.5% to 8% efficiency
Some is lost to heat, friction, etc
Practical Maximum gross 3.5% to 4.0%
25 to 30% of gross power production is needed to operate the plant
Net electric energy available is about 2.5% and 3%
