Solar thermal power plants use heat from the suns rays to create the steam that is needed to rotate the turbine. Figure 2. A boiling water nuclear power plant. Thermal power plants are all limited by the second law of thermodynamics, which means they cannot transform all of their heat energy into electricity.
In thermal power plants the heat energy produced by burning fossil fuels like coal, petroleum or natural gas is used to heat water and change it into steam which rotates the turbines of generators to produce electricity. c) Hydro power plants-In hydro power plants water from rivers are stored by constructing dams.
