Wind turbines are the main reason for an increase in the visibility of built development in Scotland. A report from Scottish Natural Heritage (SNH), the Scottish Government's advisor on nature and landscape, has shown that wind farms could be seen from 35.6% of the country in 2010, which is the most recent full year measured. This compares with 31.6% in 2009 and 19.9% in 2008. The 2010 Visual influence of Built Development National Indicator also reported that in Scotland, tall structures without turbines could be seen from 46.3% of the country, a figure that remains unchanged between 2008 and 2010. Overall, built development could be seen from 70% of Scotland at the end of 2010, an increase of 1% from 2009 and 5% from 2008. SNH chief executive Ian Jardine said the results of the study are “perhaps unsurprising, given the importance of the renewable energy sector in Scotland”. Built development overall could be seen from 70% of the country in 2010, an increase of 1% from 2009 and 5% from 2008. The report is available on the SNH website.
