Wind is a natural energy source, occurring directly at the point of use.
Therefore, there is no fuel cycle with fuel extraction, fuel transportation and processing in connection with a wind farm. The wind fuel cycle consists only of the presence of the wind turbines, their operation and connection to the electric grid. Characteristic for the wind fuel cycle is the lack of pollution connected directly to the wind turbine. However, there is chemical pollution connected to the manufacturing of materials for the turbine itself and the materials used for the electrical transmission equipment. The life cycle has the following stages, as shown in Figure 1 .
