This is what the future could look like in 2050: Electricity is mainly generated from wind and solar power. Cars are fuelled with electricity or hydrogen. Buildings are so well insulated that they no longer require heating.

How do we get there? What remains to be explored? And how is the transition towards a more sustainable energy supply to be financed? The Academies’ Project “Energy Systems of the Future” provides answers to these questions.

Energy transition studies: now is the time to create a long-term framework and technology-neutral incentives

A joint initiative of the German academies of science project “Energy Systems of the Future” (ESYS), the Federation of German Industries (BDI) and the German Energy Agency (dena) has formulated recommendations in seven action areas, aimed at helping Germany to successfully complete the energy transition and deliver its climate targets for 2050.


Biomass: striking a balance between energy and climate policies

Bioenergy is the most versatile of the renewable energy sources. A coherent bioenergy policy must ensure that bioenergy use has no negative social and environmental impacts, and makes the greatest possible contribution to climate protection.

Position Paper

Governance for the European Energy Union

The Position Paper shows how committed leadership alliances, the EU Commission and EU legislators can effectively use the Regulation on the Governance of the Energy Union and Climate Action and take more far-reaching energy policy measures.

„Its specific aim, broad approach and structural conception make the Academies’ Project ESYS unique in the field of science-based policy advice. “

Jörg Hacker
President of the German Academy of Sciences Leopoldina

„The energy transition must be implemented in close cooperation with the humanities. Thus, we can better understand the consequences that ensue for the population and ensure that the transition is realised in a socially sustainable way.“

Hanns Hatt
President of the Union of German Academies

„ESYS creates interfaces between different disciplines and stakeholders in order to develop systemic answers to the challenges coming with the energy transition. “
