How does tidal power generate electricity?
In simple terms, a tidal energy works via a turbine works like a wind turbine, with blades rotating 12-to-18 times a minute depending on tide strength. The turbine is connected to a gearbox that turns a generator, creating electricity.
How much electricity does tidal energy produce?
Estimates of tidal stream power—which uses ocean currents to drive underwater blades in a manner similar to wind power generation—in shallow water is capable of generating some 3,800 terawatt-hours per year.
What is tidal energy class 8 short answer?
Tidal energy is a form of hydro power which converts the energy obtained from tides into other useful energies (electricity). … The height difference between low and high tides gives rise to tidal currents in coastal areas, which drives the turbines. Tidal energy is also called tidal power.
What is tidal energy used for?
We can use tidal energy to supply electricity to our homes and businesses. We can use tidal energy in some places instead of burning coal and oil that contribute to global warming. Tidal generators (or turbines) work like wind turbines, except it is ocean currents, not wind, that turns them.
