You could mount a 1000 of these in the space it takes for one of the current 'wind turbines' we buy from the Chinese.
Paint them different colors or with patterns to add beauty.
There are all sorts of smaller wind generators that have come out in the last 5-10 years. Many are vertical axis like the one you pictured.
The Archimedes screw type is multi directional. It also does not have the thump-thump-thump of the large BIRD KILLERS. Plus, there is no noise/harmonic pollution either.
Most of these things are intended to be put on the edge of some warehouse or tall building/skyscraper. Where the winds are more steady.
I am not sure how any of them stand up to salt water spray or snow/ice or sand storms. One of things I have seen with the large offshore wind generators is that the leading edge of the blades becomes damaged over time just from the salt/sand/debris in the wind. Constant bombardment by the salt air beats on it just like the leading edge of an airplane.
