I think the discussion should be based on these two specific situations: 1. If the ship is powered by wind and the engine does not start, then wind energy can be used to generate electricity to that time, because the wind speed is much faster than the ship at that time. The wind speed is also strong enough. 2. If the ship is powered by an engine, using wind energy to generate electricity will certainly increase the resistance of the ship during the voyage; the speed will slow down and require more energy, so at this point the gain exceeds the loss, and it is not suitable to use wind power generation. To summarize, wind energy can be used to generate electricity. on the wind power generation system when the ship is powered by the wind, and turn off the wind power generation system when the ship is powered by the enginer. It is very easy to do, because when the circuit is cut, although the wind. The turbine will continue to rotate under the action of the wind, it idles with very little resistance and has no impact on the movement of the ship.
There are many types of generators. We have hydroelectric generators that use the potential energy of water to convert it into kinetic energy, and the kinetic energy into electrical energy.
Wind turbines use the kinetic energy of wind to rotate with the generator and convert it into electrical energy.
There is also thermal energy production and nuclear energy production. But they all convert the energy existing in nature into electrical energy. The so-called generator involves converting other forms of energy into electrical energy.
