Describe the energy changes as electricity is produced in a fossil fuel station.
To begin with, chemical energy in the fuel is released through combustion and becomes thermal energy. This thermal energy is used to heat water which evaporates and become steam. The rising steam turns turbines and the system now contains the kinetic energy of the turning turbines. The turbines are finally linked to a generator which converts the kinetic energy into electricity.
