Wind is such an element of sea environment, from which it is relatively easy to obtain energy. Wind
parameters over both seas and oceans are more favorable than those on land (due to variability of landform
features). Moreover, also sea wind turbines exercise comparatively smaller negative effect on people than on
land. Therefore, sea wind farms are ahead of us, as further development of wind energy. The article presents
basic parameters of wind turbines, possible installations on sea bed, as well as future designs of large floating
sea farms. The article presents also an example of design analyses of wind turbine, using computational fluid
dynamics (CFD).
