Yes, given there is no ‘empty land,’ you are always destroying something if you create a windfarm on land. On the other end of this, offshore windfarms unironically create local ecosystems. If your goal is not just decarbonization, but decarbonization in order to better the health of the planet, which it should be, then offshore would be the best option.

See: Germany tearing down land wind farms in order to mine more coal. Those turbines aren’t going to be repurposed, they’re going to scrap yards.
