The trend towards a further increase in the share of renewable electricity generation in Germany is continuing. In the period from 2014 to 2017, the share of renewable energies in electricity demand increased from 27.4 % to 36.2 % with electricity demand remaining more or less constant (see Figure 1 - middle). If this trend of the past four years is linearly updated, the targets set in the Energy Turnaround Monitoring Report (BMWi) for the share of renewable energies in gross electricity consumption appear achievable. Even if more electric vehicles are connected to the power grid in the coming years, the 50 % target for renewable energies in electricity consumption by 2030 can be achieved.

The situation in the heating and transport sector is much less positive. The share of regenerative heat generation continues to stagnate at a significantly low level of 12-13 %. The regenerative share in the transport sector is even lower and even declining slightly. In summary, it can also be stated for 2017 that the energy transition in Germany will continue to be limited to a turnaround in electricity supply.
While final energy consumption in the electricity sector is of the same order of magnitude as in the transport sector, the same amount of energy is used for heating as for the other two sectors combined. The "turnaround in heating" therefore plays a key role in the success of a holistic energy turnaround.
