These systems also affect recreation and navigation in the area. While tidal turbines cost more to erect than wind mills, the also generate more energy. Advantages of Tidal Energy 1) It is an inexhaustible source of energy. 1. There were three sites determined to be financially feasible: Shepody Bay (1550 MW), Cumberland Basin (1085 MW), and Cobequid Bay (3800 MW). The principle was demonstrated at London Bridge June 2019. Fig. The tidal lagoon scheme is very similar to the tidal barrage method of using tides to generate power. This form of energy is influenced by location, and speed and volume of the currents. A study was commissioned by the Canadian, Nova Scotian and New Brunswick governments (Reassessment of Fundy Tidal Power) to determine the potential for tidal barrages at Chignecto Bay and Minas Basin – at the end of the Fundy Bay estuary. The high load factors resulting from the fact that water is 800 times denser than air, and the predictable and reliable nature of tides compared with the wind, make tidal energy particularly attractive for electric power generation. Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Plus, tidal energy generation is predictable. Wave and Tidal Energy Market 2019 | Current Scenario, Growth Opportunities and Trends by Forecast To 2023 - Market report on global wave & tidal energy market by MRFR outlines that the market is set to portray its potential earnings worth USD 15,291.2 Million, having an expansion of its size at a CAGR of 17.84%.
