Height above ground is very important - raising the turbine above the turbulence is vital.
These small generators are borderline on cost/effectiveness. We have a pretty "green" house - when designing and building it, we spent some time at the Centre for Alternative Technology (CAT) at Machynlleth in Wales.
Even though our site is on top of a hill in one of the highest points in Kent, plus we have pretty much uninterrupted views from the South clockwise to the North East (the prevailing wind is SW, so clear access there), CAT stated that it was more cost-effective for us to forget photovoltaic and domestic wind turbines and to just buy electricity from renewable sources from a commercial supplier who can do this on an industrial scale. Yes, you lose that "warm feeling" of visibly doing your bit, but when you take a cold hard look at the numbers, including ALL the costs associated with doing this stuff yourself, going to a commercial supplier is generally far greener and more effective.
I should also point out that I used to work for a company whose owner also owned one of the largest domestic wind turbine companies in the UK, so I could have got a very cheap/free turbine... but the guy had installed one of the turbines at his own house (a rather magnificent Queen Anne house on top of the North Downs) and even he couldn't get it to work consistently and reliably! It was removed after a few months...
So we currently purchase off of Bulb (my referral link) which guarantees 100% renewable source electricity and use a ground source heat pump plus other green tech.
