Shell has been doing lot of questionable activity in the seas too, basically creating large explosions that kill whales and other wildlife. You'd think renewable energy companies would know better than to kill wildlife but seems when it comes to energy humans just don't care about impacts and just care about money. Whatever it is they are doing there is probably a less impactful way but it probably costs more or yields less energy so they won't even look at it. Putting the turbines on land would be a good start. They also need to look into how to prevent bird/bat deaths as they are an issue for that, although still less than oil industry based deaths. The blades being hard to recycle is another issue but I think they are actually working on that.
