Not great for the wildlife during drilling but it's better than the carbon rich alternatives.
It is really great for the wildlife after the drilling is done though, as the windmills tend to make the area safer against fishermen.
Nothing is great for wildlife, including leaving it alone and undisturbed, because nature doesn't care if animals are happy, or even if they exist.
No energy source producing the required amounts to run civilization will be non-disruptive to wildlife and the environment. But perfect is the enemy of good.
Renewable energy sources heavily reduce this factor, make countries more independent from imports (other countries) and slow down the catastrophic effects of increased atmospheric energy due to greenhouse effect of carbon-based energy sources.
Conservatives should be the top number one supporters of renewable energy because of more independence from other governments and better conservation of the environment.
But alas, the only thing they like to preserve is their personal greed.
Global warming is also killing wildlife. And by many magnitudes more than drilling some holes for offshore wind parks.
