In the case of energy services, the focus is more on the service, i.e. the benefit, than on the energy used. For example, the aim of heating real estate is not to supply heat but to provide a comfortable temperature. For the supply of electricity, the focus is more on the lighting of living or working spaces or the provision of hot water.

In the course of the energy transition, so-called tenant power projects are becoming increasingly popular. Here, housing associations install solar systems on their buildings and then let their tenants use the electricity generated. This is often significantly cheaper than from local basic suppliers.

Smart metering is an important digital trend in energy services. This involves intelligent metering systems recording electricity consumption digitally so that electricity consumption and consequently CO₂ emissions can be reduced. A smart meter can also control the supply of electrical energy to electrical devices and thus also identify electricity guzzlers. Smart metering is an important step on the way to climate-neutral building stock.

Another trend that is particularly prevalent in private households is Internet-of-Things (IoT) products. Consumers can smartly network a variety of everyday objects and thus, for example, check whether the heating is still on while on the move and thus make their energy consumption more efficient.
