Power stations use fossil fuels to produce electricity. First, the furnace will burn the fossil fuels. This converts chemical potential energy (in the fuels) to heat energy.

Second, the heat is used to boil water and turn it into steam. This converts the heat energy to kinetic energy of steam.

The steam turns a steam (a)   , converting the kinetic energy of steam into kinetic energy of turbine.
