Over two-thirds of the Earth’s surface is covered by oceans, and the theoretical energy available from that source is greater than could ever be used. The diffuse nature of the resource, and its distance from where it is needed, reduce its potential usefulness; however, it remains a valuable prospect in many locations. The sources of energy that may be considered include tidal currents, wave energy, ocean thermal energy, and salt gradient energy. Ocean thermal energy could be a prolific source of energy, since it exploits the temperature difference between warm surface water and colder, deep water. However, to date only tidal energy has seen limited commercial development, although serious work in the area has been going on for only a little over a decade. This remains a potential energy source that requires a lot of research.
Until recently, tidal energy was obtained from one type of plant — a tidal barrage. This is essentially a large dam across a river estuary. As the tide comes in, the sluice gates are opened to allow the water to flow into the estuary. As the tide recedes, the flood control gates are closed to prevent the water from flowing back except through the turbine system. It is also possible to have a barrage that generates electricity on both incoming and outgoing tides.
The difficulty with tidal barrages is that they require high tides, so there are few locations (about 20) in the world which are suitable. Coupled with the high capital costs required to build the barrages, there are few operating tidal barrages in existence. One is located in Annapolis Royal, Nova Scotia on the Bay of Fundy.

Do you advise tidal capacity as in waves or tidal capacity as in gravitational consequences between 2 more beneficial more beneficial celestial bodies? For the former you're in the incorrect solutions type. For the latter, nicely when we arise with a way of harnessing it - if in any respect a chance/least extreme priced, then like all option capacity source the advantages will be measured depending on the technique of utilising it (ie merely because the nergy source itself is non polluting, the technique of utilising/extracting the capacity will be polluting)

Well technically tidal energy wouldn't be seen as having societal impact, but it could impact the areas economy by providing cheap electricity down the road. Economically it could improve the community and really has more impact on the community rather than society. Society has a very complex makeup and although it does have a positive economical impact, it changes society imperceptibly.

Since Tidal power stations are based upon water and these are renewable source of energy that does not produce harmful gases like carbon dioxide and more, therefore they are a positive effect on the environment.

Economical, environmental, may be political ( some politicians like make hay out of it ) if the tidal energy is harnessed .
