Is it true that wind turbines on the beach can use wind power to generate electricity?

I think the discussion should be based on these two specific situations: 1. If the ship is driven by the wind and the engine is not started, then wind power can be used to generate electricity at this time, because the wind speed is much faster than the ship at this time. The wind speed is also strong enough; 2. If the ship is driven by an engine, then using wind power to generate electricity will definitely increase the resistance of the ship when traveling, and the ship speed will slow down and require more power, so At this time, the gain outweighs the loss, and it is not appropriate to use wind power generation. To sum up, wind power can be used to generate power. The specific operation is to turn on the wind power generation system when the ship is driven by the wind, and turn off the wind power generation system when the ship is driven by the engine. It is very easy to do, because when the circuit is cut off, although the wind impeller will continue to rotate under the action of the wind, it is idling with very little resistance and has no impact on the movement of the ship.
