We were asked to make a presentation about our experience of developing Allt Dearg at the Scottish Land & Estates Spring Conference in 2014.
The debate around wind farms is complex, heated beyond reason by corporate and political media spin, myth and emotion. In this frenzied atmosphere, where emotional opinion takes on scientific reason, the fundamental issues are often obscured. Most of us take electrical power and the benefits it brings to our quality of life for granted. In the western world, we belong to a generation that has always been able to light up our house with the flick of a switch. All forms of electrical power come at a cost; some of these costs are more visible and readily apparent than others. We believe that wind power should deliver local benefit and is an important part of our future energy mix. Engineers, like farmers, are not renowned for their eloquence. How does the sailor describe his feelings as the breeze fills the sail, and the boat surges forward? Exhilaration, boundless, at one with nature (clearly it feels pretty good, judging by the number of sails often visible on the waters around Allt Dearg). Come and stand beneath the wind turbines as they work, reflect that the energy they generate has been gathered from an infinite local source, with little risk or residue. Contemplate the wisdom of gathering whatever energy we can from sustainable sources, and consider how history might judge our efforts to conserve finite resources for the following generations.
How are we doing? Relative performance of wind power is a frequent area of debate and dispute. Like most wind farms, the Allt Dearg and Sròndoire output data is publicly available from various online sources. Allt Dearg and Sròndoire are usually ranked in first and second place, in terms of Annual Load Factor (the key measure of productivity) for large scale wind on the British mainland. Spurness II on the island of Sandy, in Orkney vies with Allt Dearg for the overall first place in the whole UK ranking. Further information on outputs for all renewable energy is published by the
Renewable Energy Foundation.
