Offshore wind power

Definition

Offshore wind power refers to the generation of electricity using wind turbines located in bodies of water, typically on the continental shelf. This method harnesses the stronger and more consistent winds found at sea compared to onshore sites, making it an increasingly popular and viable renewable energy source. Offshore wind power is significant for its potential to contribute to energy transition goals while minimizing land use conflicts and reducing greenhouse gas emissions.
