It was a beautiful weekend here, sunny days with blue skies, no wind, and a real chill in the air. I took the opportunity to visit the nearby wind farm for a winter walk. The views were magnificent, the panoramic vista including Ben Lomond and surrounding hills as well as the Isle of Arran. With the winds being so low, the wind turbines turned at a leisurely pace. I have mixed feelings about these farms. They provide sustainable and renewable energy, and as an engineer I am struck by the sheer size and beauty of the structures. Yet I am also wary of the impact on our wonderful countryside. In places like this they seem fine, yet up in the Highlands of Scotland I wonder at the ‘visual pollution’ they cause.

Yet as I watched the turbines slowly turn, one can’t but help be hypnotised by their motion, and I reflect on energy, entropy and the universe (did I mention I was an engineer?) If I’m ever asked, I would say my glass is half full, which they say means I have a word view that is optimistic. However, I am a firm believer that it is as important to empty the glass to leave room for something new, as continually topping up can mean more of the same. And so as I watch the turbines turn in the wind, I wonder what the future holds as the sun sets on this year, and a new year shortly begins…
