According to this https://socialinnovations.nl/enlil/ it generates 17520 kWh per years at max speed, so max 48 kWh per day per turbine. (I use about 100 kWh per day in a row house in winter in Norway, using electricity for both cooking and heating.)
So not a solution for large scale production, but I like the idea of looking for energy production in places where we've already messed up the environment.
