For example the potential energy of water 1 is converted to electrical energy in a hydroelectric power plant, coal is burnt in a thermal power station to produce electricity, solar energy is converted to electricity in photo-voltaic cells (solar cells) and wind energy is converted to electricity in a wind turbine.
