Introduction to Wind Turbines

A wind turbine uses angled aerodynamic propeller type blades which are forced to spin by even the lightest breeze. The blades are connected to a rotor which is attached to a shaft. The rotation of the blades causes the shaft to turn. The shaft connects to a generator which converts the energy into electricity.

The turbine is made up of three main components:

  • The rotor component, includes the blades and their assembly mechanism.
  • The structural support component, is the tower.
  • The generator, includes the electrical generator, the control electronics and the gearbox for converting the rotational energy to electricity.

The energy produced by a wind turbine is dependant on the speed and direction of the wind. The wind speed depends on its location in Ireland, its location on the proposed site, the height of the turbine and the presence of nearby obstructions such as trees, buildings etc. Wind speed increases with height so it is best to locate the turbine high on a mast or tower. Generally speaking the ideal siting is a hill top with flat, clear exposure, without any obstructions.

Individual turbines vary in size and power output from a few hundred watts to two or three megawatts (as a guide, a typical domestic system would be 2.5 - 6 kilowatts, depending on the location and size of the home). C-Mc Energy supplies turbines of various sizes and applications from 3Kw - 30Kw.
