Transport and Energy
Published in Richard Gilbert, Anthony Perl, Transport Revolutions, 2018
Yet another means of renewable generation of electricity is from the kinetic energy of ocean tides and currents. A comprehensive review of such opportunities for the UK suggested that marine energy could make “a reasonable target contribution to UK electricity supplies” of 80 TWh annually.200 Of this, 20 TWh would come from tidal barrages such as the one at La Rance in France,201 10 TWh would come from using the energy in marine currents in much the way the energy in wind is used,202 and 50 TWh would come from making use of the energy in waves. The UK’s estimated gross generation from all sources in 2005 was 400 TWh.203

Wave: Marine energy (also sometimes referred to as ocean energy) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world’s oceans creates a vast store of kinetic energy, or energy in motion. This energy can be harnessed to generate electricity to power homes, transport and industries.

Marine energy deals with hydrokinetic energy, which includes three types of energy: wave, tidal and current energy [8]. Wave energy is harnessed from shore-based areas whereas waves are created from wind blowing over the waters. Tidal energy is obtained from the flow of tides due to the gravity of the moon and current energy is obtained from moving ocean/river currents.
A study on Norwegian offshore policy
Published in Journal of International Maritime Safety, Environmental Affairs, and Shipping, 2020
Marine energy, which generates energy using offshore wind power and wave power, is clean energy that does not produce environmental pollution, and it pays great attention to marine energy development worldwide as a permanently available resource, not as a depleted resource like oil. Major countries around the world are speeding up the development of marine energy, the European Union is planning and preparing to supply about 10% of its total electricity needs by 2050 with wave and tidal power generation, and the United States with more than 7% of its total electricity needs by 2050. Based on its excellent geographical advantage to develop the marine energy industry, which is surrounded by the sea on three sides, Korea is also pushing for active development under the goals of “Securing the World’s Best Marine Energy Generation Technology” and “Cultivating Global Marine Energy Companies”. To this end, industry and research institutes participated under the supervision of the Ministry of Ocean and Fisheries to form and operate a “Promotion Group for Commercialization of Marine Energy” since February 2017, and are considering introducing various policies that can support companies related to marine energy.

The extensive conservation areas and areas covered by protection instruments are shown in Figure 7a; the Biosphere Reserve of the Mexican Caribbean covers the entire study area. Keystone and endangered species such as the manatee, whale shark, turtles, and the pink snail are found in the area and strict measures have been implemented for their conservation. Biodiversity on the coast of Quintana Roo is very high, there is a broad array of ecosystems, such as coral reefs, seagrass beds, mangroves, coastal dunes, tropical rain forest, coastal thickets, and wetlands (Figure 7b), intermixed with urban areas, along the coast. Given the high biodiversity, the number of ecosystems and species that could be affected by marine energy harvesting is considerable.
