I last passed them on Wednesday and one WAS WORKING! This has been the case for a few weeks. Mostly, all three have been down.
Obviously, I got quite excited that 33.33% of our turbines had sails on and was working. As just over a quarter is the efficiency rate, so let's say 8.5%.
Now in the coldest part of winter, they operate at around one fifth normal efficiency levels.
My maths suggests that this winter our local cluster has worked at an efficiency of substantially less than 2%.
LET'S HEAR IT FOR THE 'Free' power of the winds.
