Offshore wind powerOffshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape. Unlike the typical use of the term "offshore" in the marine industry, offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas as well as deeper-water areas.
Subsea technologySubsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term subsea is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power cables, seafloor mineral mining, oil and gas, and offshore wind power.
ÉolienneUne éolienne est un dispositif qui transforme l'énergie cinétique du vent en énergie mécanique, dite énergie éolienne, laquelle est ensuite le plus souvent transformée en énergie électrique. Les éoliennes produisant de l'électricité sont appelées « aérogénérateurs », tandis que les éoliennes qui pompent directement de l'eau sont parfois dénommées « éoliennes de pompage » ou « pompes à vent ». Une forme ancienne d'éolienne est le moulin à vent.
