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.
