Shore power is a more environmentally friendly alternative, as it reduces or eliminates emissions from the ship’s own generators, which normally use fossil fuels. It also helps reduce noise and vibration levels on board, improving the environment for both the crew and the environment around the port.
In order to receive shore power, a ship must normally have a shore power cable and a compatible plug that can be connected to a shore-based power source. Ports and terminals must also have the necessary infrastructure to supply shore power to ships and comply with safety and quality standards.
Shore power is increasingly used in both commercial shipping and recreational boats to reduce environmental impact and improve energy efficiency. It is part of the efforts to promote sustainable shipping and reduce climate and air pollution from ship traffic.
