Band 9: The diagram shows the way in which wind-powered energy is created and transported to the consumer. Write a report for a university lecturer describing the process.

The visual depicts the process of the creation and delivery of wind-powered energy to consumers.

The process of generating electricity with wind power has five main stages. It begins with the placement of special machines in a suitable location. These devices include important components such as a wind rotor and multiple blades. Thanks to the wind, the rotor and blades start turning, and the spinning generator produces raw electrical output, which is transmitted to the transformer later. In case of the absence of wind, when the blades cannot turn and remain motionless, storage batteries are used.

The transformer converts the raw electrical output obtained in the earlier stages to a useable form. This phase is accompanied by a roughly fifty-times increase in the number of volts. Then, electrical power at 38,000 volts is transported through high-tension lines to consumers, who can use it for different needs in their everyday lives.
