Method and device for energy transfer

The method involves metering power consumption of active load units (4-6) which are directly supplied with energy by power generators (8). The missing amount of energy is supplied by switching on additional peripheral power generators and/or from energy storage (10) or from central energy supply grid (1) and power consumption of load (3) is reduced if metered over-consumption of load units is above threshold value. The active load units are directly supplied with energy by power generators. The current collection from generators is reduced or excess amount of energy is fed into storage and power consumption of load is increased, if metered power consumption of load is below a threshold value, such that power from generators or from renewable energy sources or from storage is not fed into central energy supply grid. An independent claim is included for device for supplying power to loads.
