A wind turbine creates reliable, cost-effective, pollution-free energy . It is affordable, clean and sustainable . ... Because wind is a source of energy which is non-polluting and renewable , the turbines create power without using fossil fuels. That is, without producing greenhouse gases or radioactive or toxic waste. Unfortunately they are a bit of a blot on the landscape. Not too bad here, but I've been shocked how much they've changed the landscape, when I've travelled back to my native UK.
