“…Not only for economic reasons, but also for further climate protection, all energy supply must be converted immediately to 100% renewable energy with sector coupling. Fossil fuels, with or without carbon capture and storage and nuclear energy, are not only more expensive [9], [10], as recently also clearly confirmed by the IEA in the World Energy Outlook 2021 [11], but also incompatible with a timely transition to a climatefriendly economy. To be able to achieve compliance with the Paris Agreement in Germany, the Berlin-Brandenburg capital region must develop a clear plan for the use of renewables.…”

The German states of Berlin and Brandenburg are committed to the Paris Agreement with the goal of keeping global warming safely below 2 degrees to protect the Earth system from uncontrollable warming. This claim implies targeting 1.5 degrees to keep a reasonable chance of realisation. Renewable energies are the only sources that can be considered to accomplish this task. We use a linear cost minimization model for the Berlin-Brandenburg region to show how a 100% renewable energy target is possible without relying on contributions from other regions. We find that a 100% renewable energy system based predominantly on photovoltaics on buildings and on green hydrogen production, and a transition essentially to electricity for all purposes, is feasible in time and at a reasonable cost below that of fossil-nuclear energy. Hydrogen storage technology appears as one of the key cost determinants, while a sensible integration of German and European transition systems potentially limits costs to the lowest levels ever realized in real terms.

The supply security of fossil gas has been disrupted by the Russo-Ukrainian War. Decisions to relocate the production and transport of gas have become so urgent that new long-term contracts are imminent that undermine the Paris Climate Agreement. Here, we simulate how quickly the addition of renewable electricity and the installation of heat pumps can substitute enough gas to reduce supply risk, while taking a decisive step towards meeting the Paris Agreement. Our bottom-up modelling, using Germany as an example, shows technical pathways on how installing heat pumps is one of the fastest ways to reduce gas consumption, in addition to reducing the load hours of gas-fired power plants. With targeted efforts, maximally 60% of gas from the Russian Federation can be substituted by 2025 with heat pumps and grid expansions, and enough electricity will remain available that the phase-out of coal and the entry into e-mobility will still be practicable.
