Evolution in size of offshore wind turbines. 0 comments

The size of wind turbines, both in rated power and rotor diameter, has increased tremendously during recent years. Why has this happened and what are the implications for the needed area for wind farms?

Learning outcome.

  • Knowledge about the increase in offshore wind turbine size during recent years.
  • Knowledge about key drivers for the increased size and challenges related to this development.
  • Understand why the increase in turbine size has limited implication on the area needed for offshore wind farms.


After having watched the video, reflect upon the following:

  • In addition to the issues mentioned in the lecture, which issue will you add pro and con bigger turbines?
  • Which issues may modify the result that the size of a wind farm is independent of wind turbine size?
