In a Nutshell! | June 2022
Unavoidable CO2 emissions must be removed from the atmosphere and stored in order to achieve “negative emissions” in this way. What exactly negative emissions are, how they can be generated by nature-based and technological processes, and the advantages and disadvantages of different methods are explained in the new edition of our “In a Nutshell!” format.
Discussion Paper | December 2021
The next four years will be key to Germany’s climate ambitions. During the term of the new parliament, Germany can either choose to drive climate action both nationally and internationally, or it can pass up this chance and stand idly by while the windows of opportunity close one by one.
Position Paper | April 2021
Over the next two decades, the energy transition and the growth of digitalisation will result in new risks to the electricity supply. A resilience strategy will be required to manage these risks and reliably prevent blackouts and their damaging impacts on society. The “Resilience of digitalised energy systems” working group of the Academies’ Project “Energy Systems of the Future” has identified points as the key pillars of any such strategy.
Position Paper | April 2021
The energy transition and the European Energy Union are placing new requirements on electricity grids. Any ongoing grid congestion may well cause high costs and additional risks to grid stability, which can be countered by adjusting the market design. This position paper sets out five policy options.
Position Paper | April 2021
How should the market be designed to enable efficient climate protection in Germany and drive sector coupling forward? A comprehensive carbon pricing scheme and a reform of taxes, duties and surcharges are key components. This position paper categorises the decisions from the Climate Action Plan 2030 and sets out options for how revenue from carbon pricing can be put to use to achieve a double dividend for climate protection.
In a Nutshell! | November 2020
In 2018, CO2 emissions in Germany have fallen noticeably to 866 million tons for the first time since 2014. This is shown by calculations of the German Environment Agency. These figures are not enough to achieve the climate protection targets. Why don't emissions decrease more significantly, even though wind power and solar plants are being steadily expanded?
Ad hoc statement | June 2020
The present ad hoc statement by the German National Academy of Sciences Leopoldina, acatech – National Academy of Science and Engineering, and the Union of the German Academies of Sciences and Humanities aims to provide the German government, in light of its upcoming presidency of the EU Council, with a compact series of recommendations for giving the desired European energy transition the momentum it requires, not least amidst the challenge posed by the coronavirus pandemic.
Position Paper | April 2020
A mix of centralized and decentralized technologies is the only way to ensure a climate-friendly, secure and economic energy supply. The position paper suggests astute ways of combining centralized and decentralized components to create a stable and sustainable energy system.
In a Nutshell! | January 2020
While Germany is committed to shutting down all its nuclear power plants by 2022, other countries such as China, Russia and Japan are increasing the share of nuclear power in their energy mix. What role will nuclear power play in the future of both global electricity generation and climate protection?
Discussion Paper | September 2019
Based on their studies into the feasibility of the energy transition by 2050, the German Academies of Sciences' joint "Energy Systems of the Future" (ESYS) initiative, the Federation of German Industries (BDI) and the German Energy Agency (dena) have published a discussion paper with recommendations how Germany's energy transition can succeed. ESYS, BDI and dena have jointly concluded that, although feasible, an energy transition can only be achieved if policymakers take immediate decisive action. A "business as usual" approach will result in Germany comprehensively failing to meet its climate targets.
Position Paper | May 2019
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. The Position Paper shows how to make best use of bioenergy in the energy system.
Position Paper | April 2019
The Position Paper shows how leadership alliances, the EU Commission and EU legislators must make effective use of the scope of the Governance Regulation and points out options for accompanying measures.
Position Paper | August 2018
How can we drive fossil fuels out of the energy system and achieve our climate targets? Based on expert discussions, a comparison of relevant energy scenarios and their own model calculations, the Academies’ Project ESYS has developed a list of courses of action for Germany. The Position Paper has summarised the most important results.
Position Paper | March 2018
The supply of metals and energy products depends on various factors, i.e. how raw material prices develop, or how transparent and accessible the markets are. The position paper describes how Germany can become more independent of raw material imports and what measures can help to secure the supply in the long term.
Position Paper | March 2016
Energy scenarios can considerably influence political decisions. It is therefore of major importance that the results are both comprehensible and verifiable. However, as calculation models are part of the implementing institutions’ operating capital, they are frequently not disclosed. Also, it is not always clear whether the results are influenced by any provisions by the commissioning institutions. The position paper by the Academies’ Project “Energy Systems of the Future” (ESYS) offers suggestions how transparency can be increased.
Position Paper | February 2016
So-called flexibility technologies are necessary to balance the fluctuations naturally inherent to power generation from wind and photovoltaics. A working group of the Academies’ Project “Energy Systems of the Future” (ESYS) has developed a special model enabling the comparison of 130 different constellations. The position paper summarises the main findings and presents design options for energy policies.
Position Paper | July 2015
In order to mitigate global warming, as many countries as possible must strive to make their energy supply systems more sustainable. It is up to the EU to establish an integrated energy and climate policy as an internationally compatible system. Therefore, this position paper advocates the closer integration of the German energy transition into the European energy and climate policy scheme.
