The use of fossil fuels, particularly oil, in the shipping industry has been the dominant form of energy for decades.
However, the oil era of shipping is coming to an end due to increased awareness and concern about environmental impacts.
The environmental impacts include burning fossil fuels, such as air pollution and climate change.
It also includes the rising costs of oil, which can make alternative energy sources more attractive.
Alternative energy sources, such as electric and hydrogen fuel cells, are becoming more viable for use in the shipping industry.
Government regulations and incentives are aimed at reducing the use of fossil fuels in the shipping industry.
There is an increased adoption of more efficient and environmentally-friendly shipping practices, such as slow steaming.
There is a growing demand for sustainable and responsible practices from consumers and companies.
The emergence of new business models, such as shared shipping, which can reduce the overall demand for energy in the industry is also a factor.
