The better wind conditions help, but offshore wind is really expensive. Transport and install alone for a big offshore turbine can easily cost EUR 1-2M. Add to that undersea cables, higher maintenance costs (salt water, difficult access) and it is clear why onshore wind (if possible) is still the preferred choice. Nonetheless, mainly due to the up-scaling and abundance of available ocean space offshore wind has taken off in the last few years.
