Global Energy Systems

The Global Energy System Modeling Group is part of PIK's Research Domain III. We explore sustainable energy transformation strategies with a special focus on:

  • the requirements for as well as benefits and risks of climate change mitigation in line with internationally agreed long-term climate objectives, such as the goal of limiting global warming to well below 2°C;
  • the adequacy of current national, European and international climate and energy policies in the light of these long-term targets;
  • the potential contribution of renewable energy sources to the decarbonization effort, e.g. in the context of the German Energiewende;
  • the environmental footprint (climate and non-climate) of the energy system, and integrated sustainability strategies.

Our main research tool is the integrated assessment model REMIND (detailed description via ADVANCE wiki) which allows us to study the complex interactions between the energy system, the economy as well as the climate and environment.
