Adjusting to green energy consumption in an energy consuming system

An energy metering device for allowing energy consuming devices in a group of energy consuming devices to adapt to green energy consumption, the energy metering device comprising:

• a power measurement unit operative to measure the energy consumption of the group of energy consuming devices, and
• a processor and a memory, said memory containing instructions executable by said processor whereby said energy metering device is operative to
• compare the measured energy consumption with an energy consumption threshold, said energy consumption threshold representing a level below which renewable sources are used for the generation of energy, and
• indicate (I) to energy consuming devices of the group if the measured energy consumption is on one of the two sides of the energy consumption threshold for allowing them to adapt their energy consumption.

A method for adapting to green energy consumption in an energy consuming device belonging to a group of energy consuming devices associated with an energy metering device, the method being performed in the energy consuming device and comprising:

• receiving, from the power metering device, an indication (I) that the energy consumption of the group is on one of two sides of an energy consumption threshold, said energy consumption threshold representing a level below which renewable sources are used for the generation of energy;
• investigating if the energy consumption has crossed the energy consumption threshold, said investigation comprising investigating received indications;
• and
• adjusting the own current energy consumption if the energy consumption is found to have crossed the energy consumption threshold.
