Letter: Wind turbines a threat to climate

Wind turbines a threat to climate

Sir: It seems to me that wind turbine generators cannot be as harmless as people assume (letters, 9 January). Wind carries energy, hence the use of wind farms to generate electricity. The turbines remove this energy from the wind and take it elsewhere.

Global weather is a chaotic system. The essence of chaos theory is that small changes in one part of the system lead to drastic and unpredictable changes in other parts of the system.

I believe that the removal of energy from the wind could cause large- scale changes to wind systems in other parts of the world. Thus wind farms could conceivably cause just as much climatic damage as the fossil-fuel- burning power stations they are supposed to be replacing.
