Earth rotation alongside the atmosphere’s heating leads to creating wind, so solar energy is the source of wind indirectly. One of the potential solutions to reduce GHG emissions from the shipping section is a throwback to around 1300 century BCE and used wind energy as propulsion, or at least assisted other energy sources to propel the ship. Like other technologies, the wind energy sector developed, and researchers tried to present efficient methods to use wind energy. There are several options in order to use wind energy on-board. The most efficient of them listed above, each of which is capable for specific types of ships.
Wind energy, same as the solar energy is a natural phenomenon and the efficiency of wind power generators directly depends on location and weather conditions because the speed and direction of the wind are different by changing the latitude and longitude. The mean wind speed around the world has been shown in Figure below.
