The decarbonisation of the energy system is among the most important challenges of the twenty-first century. The energy sector accounts for approximately two thirds of global CO2 emissions. Hence, the development of a low-carbon energy supply based on renewable sources represents an essential entry-point in the fight against climate change. The deployment of renewable energy is also linked to important co-benefits, including improvements in air and water quality. But the energy transition is more than the development of new infrastructures and technologies; it entails far-reaching changes in society and the economy. It changes natural landscapes, drives the development of new social practices and ways of life, reassigns responsibilities, reshapes governance and political alliances, and redistributes power. In Germany, the energy transition has fostered the spread of energy cooperatives and other innovative organisational models. As a frontrunner in the transformation of its electricity system, Germany represents an important learning ground in the search for sustainable models of energy production and consumption.
The IASS investigates the complex change processes that underpin the energy transition across multiple research projects and develops solutions to foster sustainable outcomes. This research is underpinned by an approach focussing on the interdependencies and interactions between innovative technologies, new business models and organisational structures, evolutions in governance, and emerging lifestyles and practices of adaptation. The study of the social dimension of the energy transition and the integrated assessment of various socio-technical options for the development of a low-carbon energy system form a particular focus of this research. Research activities at the IASS also explore the international dimension of the energy transition and the role of Germany as a potential driver of a global energy transition. Our researchers monitor and assess key processes, including the efforts of G20 states to transform the global energy system, and study developments in major emerging economies.
