Offshore wind turbines are somewhat more costly to set up than land wind turbines but they have the advantage of being intrusive, and therefore are less limited by size and sound limits.
Also as there are no obstacles out on the water like land shapes, buildings and trees, the wind speed is generally ample faster and much more dependable, and therefore offshore wind turbines generally have higher energy yields than land-based houses.
Offshore wind turbines are built approximately10 kilometers from land and are constructed both in the sea and in the center of large lakes. If you want to know more then you can simply browse http://www.fredolsen.no/

Constructing offshore turbine towers introduces particular issues, mainly in building the foundations down into the sea/lake bed, and also constructing underwater power cables to transmit the electricity back to the main grid.
Repairs and maintenance prices will also be greater since the towers are vulnerable to an intense component, also so for those wind farms which are located in saltwater, corrosion may be a costly and time-consuming issue.
The greater return of offshore wind turbines means the true price of converting the wind power to electricity is comparatively low.
These wind turbines are frequently quite big, using as much as 100 tanks in operation at the same time and they’re able to operate quite solidly against smaller onshore installations.
Because of this, it’s very likely that offshore wind turbines will probably be the primary supply of wind power for a while, regardless of the greater setup and operating costs.
