Question : 36 [SSC SIG 2005]
Tides in the sea have stored in them :
a) A combination of all the above three forms of energy
b) Gravitational potential energy
c) Hydraulic energy
d) Kinetic energy
Answer »Answer: (b)
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.
Tidal barrages make use of the potential energy in the difference in height (or head) between high and low tides. When using tidal barrages to generate power, the potential energy from a tide is seized through the strategic placement of specialized dams.
When the sea level rises and the tide begins to come in, the temporary increase in tidal power is channelled into a large basin behind the dam, holding a large amount of potential energy.
With the receding tide, this energy is then converted into mechanical energy as the water is released through large turbines that create electrical power through the use of generators
