Plans have been lodged for a roof-mounted wind turbine in the heart of one of the industrial estates in Perth (Scotland). Scottish and Southern Energy (SSE) has applied to Perth and Kinross Council for the small turbine, which will be based at Dunkeld Road, Perth, and measures four square metres. The move is part of SSE’s £293,000 agreement with Edinburgh-based Renewable Devices Swift Turbines Ltd, which is over a 30-month period. As a result, SSE expects to place nearly 2,000 orders, worth up to £9 million, over the next three years. The wind turbine is expected to provide 30% of the electricity needs of an average semi-detached house and reduce carbon dioxide emissions by 1.8 tonnes per year.
