  Hmm no,

  • first oft all: noise. Wind turbines have moving parts, that attached to a building or even worse attached to a balcony creates noise in the whole building. Imagine the rattling of 5-6 ~10 year old, bad maintained, wind turbines.
  • Second: the energy output is rather low. A 1,2KW turbine is about 1.2m/3.9feet big. That’s in spherical, cause it has to be able to rotate by wind direction.
  • Third: balconies are preferred to not have wind, but sun.
  • And last but not least: blades. Every windturbine form factor has (fast) moving blades. If it’s reachable someone is going to stick a finger in it.

  If you’re living more suburban and have a windy detached place to setup a small windturbine that’s an option. On the garage or shed for example.

  Doubt it. Wind around buildings tends to be shit.

  There’s a reason they build turbines on hilltops and out at sea.

  Sadly really small wind turbines are really ineffective and not worth the investment until you have a really windy balcony. If you only have a few square meters solar is the only choice.

  But I’d still love to have a small windmill in my garden.

  If everyone puts wind turbines on the balconies they might end up blowing the building over
