Full electric ferries do not use fossil fuels, reducing emissions of harmful gases such as carbon dioxide, thus protecting water and air quality. Additionally, they operate with lower noise levels, reducing noise pollution for coastal residents and marine life. Electric ferries are highly energy-efficient, with lower maintenance and fuel costs, and can be charged using renewable energy sources. Furthermore, government policies supporting and subsidizing electric ferries further promote their adoption and technological development, fostering sustainable growth in the shipping industry.
