A P-V diagram is generated as a heat engine is taken through a cycle. Entropy can decrease locally (in a subsystem). [1] H.D. Each part of the cycle is easily identifiable, and the actual efficiency as well as the maximum possible efficiency can be easily determined. For example, in thermal power plants, they generate electricity by converting potential energy gathered from fossil or nuclear fuels into thermal energy which is in turn converted into mechanical energy used to drive electric generator. 8')AbTFd9$9_\.
