Local Twitterer @zathras (have to be careful how to describe one who Tweets !!), Strathearn Resident and apparent web wizard has put together an excellent website that pulls together all of the publicly available data on Scottish Wind Farms. What you have at the end of this technical genius is a simple statistical website that shows the efficiency of the wind farms along with the subsidies being paid to them.
Makes very interesting reading and can be found at www.variablepitch.co.uk
