|
None of the above

Detailed explanation-1: -Tidal power can damage marine life, as tidal turbines with their rotating blades may lead to deaths of living creatures in a sea. Noise from the rotation of the turbines may also impact fish habitations in tidal power locations. Tidal energy can also impact the quality of water and sediment processes.
Detailed explanation-2: -Tidal power is a promising renewable energy source, but production costs, a limited number of suitable locations, and technological challenges hinder its expansion. Tidal power leverages the rise and fall of oceanic tides to capture potential or kinetic energy and convert it into other energy forms, often electricity.
Detailed explanation-3: -The potential areas with low/medium tidal wave strength are in the Gulf of Khambat, Gulf of Kutch & southern regions in Gujarat, Palk Bay-Mannar Channel in Tamil Nadu, and Hoogly river, South Haldia & Sunderbans in West Bengal.
Detailed explanation-4: -Initial construction cost is very high. Formation of silt behind the barrage. Effect on animals and plants living near tidal stations. Very few suitable sites for constructing barrages. Disturbs migration of living creatures in the ocean. More items •19-Nov-2019
