At present, people obtain electricity by building dams on rivers and building hydropower stations, but there are few places on the earth suitable for dams, and dams will also destroy the ecological environment. In contrast, the surface of the earth covered by the ocean. The waves on the sea are rolling, Day and night, there is a huge amount of energy, the collection of wave energy is suitable for a wide sea area, and the ecological environment is less damaged. Therefore, collecting wave energy for power generation will have more advantages than building a dam on a river.
The statement 'Whether it is to build a tower on the seabed to support power generation, or to fix the generator on the seabed, it will cost a lot of money, and the cost is much more expensive than a river power station' if true, makes it impossible to question the above point of view.
