Shore power is the renewable energy source for ships in port. Pollution of air in ports, cities and fjords can be removed by using shore power.
Shore power is electric power from the land power plant to the electric system in ships allowing the ships to turn off the generator. Using shore power removes air pollution and noise as cruise ships, supply boats and coastal route no longer have to use diesel generators. Electrification and transition from fossil to renewable energy sources use is a priority and increasingly becoming a legal requirement in many ports. With the new regulations in EU's Fit for 55 onshore electrical power supply will be mandatory by 2030 in core EU ports.
