There's a familiar chorus of criticism when it comes to renewable energy - what happens if the sun doesn't shine or the wind is calm? But that certainly isn'...

Does anyone know about the environmental impact of these? I sometimes hear about boat propellers hurting wildlife, so what about these?

I’m almost an 11h drive from the nearest coast, so this is not an area of knowledge I am well versed in haha.

    The problem with these structures is usually small marine life - they tend to need frequent maintenance to remove barnacles and whatnot.

    Having your smooth walls and turbines lined with barnacles tends to impact performance significantly.
