sunny days of summer heat is absorbed by water flowing in roof-mounted tubes, and the hot water is pumped down to the water-storage tank. Heat is exchanged with the water in the tank. During the winter the heated water in this well-insulated storage tank is used as a source of heating.
Hydraulic power generation
Commonly known as hydroelectric power generation, this important use of water relies on the potential energy stored by a body of water.
All substances have potential energy due to their position. Since they flow, liquids can be used to transfer this form of energy into kinetic energy in a controlled way. The kinetic, or movement, energy can be transferred through a turbine
to drive a shaft of an electric generator, thus converting the potential energy of water through kinetic energy to electrical energy.
(Below) A hydroelectric power station is an excellent example of how water can be used to convert potential energy to kinetic energy (and thus eventually be the cause of electricity power generation).
