A wind turbine comprising a power supply, an energy storage device, an electric motor, control circuitry and a breaking resistor;
- wherein the electric motor is in occasional electrical contact with the breaking resistor such that a first current flows through the breaking resistor and excess kinetic energy of the electric motor is converted into heat;
- and
- wherein the power supply is configured to cause a second current to flow through the breaking resistor such that the breaking resistor produces heat, and the breaking resistor is arranged relative to the control circuitry and the energy storage device such that the breaking resistor provides heat to the energy storage device and the control circuitry.
