1. Diagram - Wind Energy

The diagram illustrates the process for generating electrical power from wind, including the stages and the equipment used. Overall, it can be seen that the process has three main stages. First, wind energy is captured with a turbine. Next, it is turned into mechanical power. Then it is turned into electrical energy and sent to the national electricity network.

In order to produce electricity from wind, firstly a large wind turbine must be installed, which rotates when the wind is blowing. The wind energy causes the turbine to spin, and then a set of gears in a gearbox converts the slow spins of the large turbine into a much faster spinning motion. In this way significant mechanical energy is produced from the wind energy.

Following this, the mechanical energy is transformed into electric power in a generator. Next, this electrical power moves to a power interface where it is then loaded onto the electricity grid. Throughout this process a control system ensures that the amount of energy going through the system is managed. Finally, the electrical energy can be transported large distances across the electricity network and used by devices across the network area.
