In view of the threat of climate change, the energy supply system, developed over more than a hundred years, with its energy supply chains and energy consumption patterns is planned to be largely replaced by a new system protecting the climate and the environment by the year 2050. An optimisation of the existing system alone will not suffice to reach the necessary climate protection goals. Due to the accelerated phase-out of nuclear power in the wake of the reactor accident at Fukushima in 2011, time pressure and the need for action in Germany are particularly great, since the shut-down of nuclear power plants leads to an increasing combustion of coal for power generation, which has negative effects on climate development. The large energy supply companies have so far invested very little in the expansion of power generation from renewable energies and economically still strongly depend on their fossil fuel-based power plants. Since it is not yet clear which new technologies are suitable for renewable power production - especially for the energy transition - and will establish themselves in markets, they are holding back large investments for the time being.EnglishopenAccessBottom-up energy transition.
