It looks to me as though the case for small, sub-2kW roof-mounted turbines is now dead: every installation that has published results shows them to be useless.

The 6kW turbines are more promising but again the actual power output is frequently well below what the manufacturers suggest is possible. There is a 6kW Proven at the SmartLife Centre in Cambridge that has been in place for over a year (clearly visible from the A14 Northern By-Pass) and the output to date - which is displayed on an screen inside the building - has been bordering on the embarrassing.
