The Onshore wind energy industry encompasses all wind projects and wind farms that have been built on land. It currently accounts for approximately 95% of the wind energy produced (source: Global Wind Energy Council). The locations of these wind farms are mostly arid and flat areas where the wind patterns result in greater efficiency and production of electricity.
Offshore wind energy is comprised of all wind farms installed in large bodies of water, seas and large lakes, and, by the end of 2018, it accounted for 5% of all wind energy produced (source: Global Wind Energy Council). Offshore projects are developed in areas where the ocean floor is relatively low (between 25 and 50 meters) so that the support structures for the equipment can be fixed to the ground.
