A
Tidal power is a green energy source as it does not emit greenhouse gases
B
Tidal currents are highly unpredictable and inconsistent
C
Electricity can be generated from tides much more efficiently at slower speeds
D
Construction cost of tidal power plants is high but maintenance costs are ralitvely low
Benefit of tidal power is that it is predictable. The gravitational forces of celestial bodies are not going to stop anytime soon. Furthermore, as high and low tide is cyclical, it is far easier for engineers to design efficient systems, than say, predicting when the wind will blow or when the sun will shine.
