Many ports worldwide are changing their illumination solutions for new technology that is more energy efficient. The port of Helsinki (Finalnd) deployed during 2019 their new system that is easier and more flexible to use. This system facilitates a smarter management, saving euros and CO2. Now the port terminal lighting is automated and can adapt better to the different usage of the space. In the Port of Bilbao (Spain), the new lighting system saves up to 50% of the energy from the previous one. The new LED technology and smart management system is more flexible and has also improved the comfort of the workers. The port of Gijón, also in Spain will receive new financing to improve the lighting, following the same scheme. In the case of Lisbon (Portugal), on the main terminal recently changed as well to LED lighting system, saving up to 13 426 kg CO2 per year. We can find examples worldwide such as the case of Vancouver (Canada), where new industrial facilities in the port also implementing new systems using LED and movement sensors. Or the case of San Antonio in Chile, where the new headquarters of the port will save up to 44% of its energy demands for lighting. These initiatives may not be as revolutionary as other complex projects introducing new fuels or energy sources, but they are gradually implementing energy savings and reducing the carbon footprint of the ports.
