In 2010, more than half of the world population lived within 150 km along the 1.6 million km of coastline that border the seas and oceans .
This is a very favorable factor for the installation of coastal energy production since production and consumption have an interest in being as close as possible .
France, in particular, has an exceptionally vast coastal and maritime domain and still unexploited .
Why marine energies?
A majority of consumers are found near the coasts and therefore potentially wave or wind fields.
It is also necessary to provide them with energy without excessive transport which would reduce the quantity delivered.
The power and size of the fields can be adapted to markets and environmental conditions.
Significant synergy already exists between wave and wind power, as well as other marine and industrial technologies.
The project can be regionalized in terms of the essential structures, modules and assembly, thus generating a significant share of local supplies and services , including installation at sea .
The local economy can therefore only directly benefit from this new industry.
L’évolution de l’espèce humaine est étroitement liée aux énergies. La maîtrise des forces naturelles et la découvertes de sources primaires, du bois d’abord et progressivement jusqu’au pétrole, ont permis à l’humanité de multiplier drastiquement la seule force dont elle disposait à l’origine, à savoir la force musculaire.
Les énergies, souvent associées à l’eau, deuxième mamelle de l’humanité, sont donc logiquement à la source de tout développement industriel.
Malheureusement cet emballement technologique trouve ses limites lorsque la ressource primaire est finie et non renouvelable et qu’en même temps leur utilisation effrénée et polluante génère des conséquences dramatiques pour l’environnement.
Hence the growing interest of the industry in renewable energies and in particular marine energies, which are inexhaustible and clean.
The evolution of the human species is closely linked to energies. The mastery of natural forces and the discovery of primary sources, wood first and gradually to oil, have allowed mankind to dramatically multiply the only strength it originally had, namely muscle strength. The energies, often associated with water, the second breast of humanity, are therefore logically at the source of all industrial development. Unfortunately, this technological boom finds its limits when the primary resource is finite and non-renewable and at the same time their rampant and polluting use generates dramatic consequences for the environment. Hence the growing interest of the industry in renewable energies and in particular marine energies, which are inexhaustible and clean. Another important corollary is the distribution of energy on the places of decentralized production and therefore with the minimum possible transport, which also allows marine energies because of the historical distribution of the populations in the vicinity ribs, as shown above
The kinetic energy of the oceans is immense and renewable with a very considerable exploitable global potential.
The World Energy Council (*) has estimated at 10% the theoretical amount of annual global electricity demand that could be covered by wave energy
(including 40 TWh / year for metropolitan France alone).
