The results of the Energy Savings Trust wind trial were published this week. This trial monitored both the performance of building-mounted turbines and turbines mounted on free-standing poles. In line with the previously published Warwick Wind Trials the study concluded that location is the most important factor affecting the performance of a wind turbine.

Rural locations with high wind speeds make the installation of a wind turbine attractive and the trial found that well-sited turbines produced outputs broadly in line with manufacturers claims. Turbines mounted on the side of urban and suburban buildings did not produce as much energy as predicted and in one case consumed more electricity than the unit generated over the year.
