Wind turbines are generally noisy, expensive and ineffective sources of renewable energy. A recent breakthrough made by Earth 4 Energy made this last sentence not so true, as it offered the ability to teach individuals how to make their own wind turbines. These turbines were small enough to be discrete but powerful enough to make a difference to electricity consumption from the electricity grid. The earth 4 energy review brags about how the turbines are extremely cheap and simple to make, which seems like a winner in my point of view. I hate noisy neighbours so if I had wind turbines they would have to be very quiet indeed.
