Question

how is tidal energy produced? state major area of its availibility?

Answer 1

Tidal power, also called tidal energy , is a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity.
Although not yet widely used, tidal power has potential for future
electricity generation . Tides are more predictable than wind energy and solar power. Among sources of renewable energy , tidal power has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability. However, many recent technological developments and improvements, both in design and turbine technology indicate that the total availability of tidal power may be much higher than previously assumed, and that economic and environmental costs may be brought down to competitive levels.
