Marine energy, also known as ocean energy, ocean power, or marine and hydrokinetic energy, refers to energy harnessed from waves, tides, salinity gradients, and temperature differences in the ocean. The movement of water in the world's oceans stores vast amounts of kinetic energy, which can be converted into electricity to power homes, transportation, and industries.
Marine energy includes wave power, which is derived from surface waves, and tidal power, which is obtained from the kinetic energy of moving water. Offshore wind power, however, is not considered marine energy because it is generated from wind, even if the wind turbines are located over water.
The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential of providing a substantial amount of new renewable energy around the world.[1]
While marine energy is a sustainable alternative to fossil fuels, its development can impact marine ecosystems, wildlife, and the physical environment. Potential effects include habitat disruption, noise pollution, and electromagnetic fields from subsea cables, which may require mitigation strategies such as fish-friendly turbine designs and environmental impact assessments.[2]
Government policies, economic incentives, and regulatory frameworks contribute significantly to advancing marine energy, with countries like the UK, Canada, and South Korea leading in tidal and wave energy projects.[3]
