Beeing Belgian i always try to find a compromise, so, needless to say, I might get shot for saying this, but cant we add a large pole on top of all windmills and attach a turbine on the end of it?
Or even better, harness the kinetic energy of the windmill's blades spinning to generate electricity... This way, it maintains the outer aesthetics of the windmill highlighted in Phillip's post prior to this one.
Furthermore, this also means that oceanic wind turbines will no longer be needed, therefore saving ? for maintenance.
