I took this photo of my son Adam, standing next to a wind turbine at Rheidol Wind Farm, Aberystwyth.
As you can see the turbines are huge.
I think the whole wind farm thing will fizzle out in years to come as they are definitely NOT cost effective. Landowners and the energy companies make a lot of money out of them via government subsidies and the government gets to feel good about itself regarding green credentials etc.
Many 'green' campaigners (notably James Lovelock) don't go along with the whole wind farm industry and I think it will be looked back on with horror in years to come.
