Wind turbines produce power from the wind to keep the yachts battery bank charged. They play a very important role in the energy mix of every eco yacht. They are a stable source of power throughout the day, but also at night and in cloudy weather, when the yacht cannot rely on solar power. Energy is produced not only under navigation but also while docked. Using a sustainable power source, wind generators can operate in various wind conditions, starting from very light winds to stormy weather. The turbines are usually placed atop of the eco-friendly yacht to maximize the conversion of wind power to electricity.
