People looking to save money on their electricity bills using microgreneration - such as solar panels and wind turbines - could actually lose money if they're not in the right location, it has been claimed.
According to a comprehensive new report by the Energy Saving Trust (EST), some households who use the latest energy generation techniques could earn the equivalent of £2,800 a year.
However, some places would actually lose money if they installed a small-scale turbine on their property.
Simon Green, the EST's head of business development, said: "Because the turbines are seen as a new, emerging technology, there has been very little proper monitoring and performance assessment."
"The fundamental conclusion is location, location, location," he added.
The two-year investigation involved the monitoring of turbines in 57 locations from the south-west of England to the Orkney Islands.
Meanwhile, the government recently gave its backing to a new competition to find the most energy efficient public building.
