Power plantEnergy Education
Thermal power plants are all limited by the second law of thermodynamics which means they cannot transform all of their heat energy into electricity.This limits their efficiencies which can be read about on the Carnot efficiency and entropy pages. Renewable Renewable energy power plants get their energy directly from their respective flows in order to generate electricity.
