Ken Watts (Letters 11/25 December) says 'it is difficult to argue against the use of renewable energy as a general concept'. He is right.
Unfortunately, he then goes on to argue against the use of wind turbines (currently our only commercially feasible source of renewable energy) because they only provide 'quite small gains' and cause 'loss of visual amenity'.
Can it be that he is unfamiliar with the large power stations that supply the bulk of the country's electricity? A trip to the Lower Trent or Aire valleys would provide a few lessons, not only in loss of visual amenity, but in air pollution on a grand scale. Compared with these monsters, wind turbines are positively idyllic.
Reassuringly, regardless of petty opposition, wind generation is gathering momentum. Yes, each wind farm is relatively small, so we will need a lot of them to replace the existing power stations. This will take a long time, so we had better get on.
