Abstract: A method of controlling power to a device which consumes energy from an energy network. The network has a renewable energy generator and a mains supply connected thereto to supply energy to the network. The method includes determining energy requirements of the device, and determining a renewable energy component of the supplied energy generated by the renewable energy generator. The method compares the energy requirements of the device with the renewable energy component of the supplied energy, and controls the energy to the device in accordance with the comparison between the energy requirements of the device with the renewable energy component of the supplied energy.

Abstract: A method of controlling power to a plurality of devices on an energy network, wherein each device has an identifier which uniquely identifies the device on the network, the method comprising: forming a group of devices from said plurality of devices; and controlling the power of other devices in said group in accordance with the state of the power supplied to a first device in said group.
