Headline: Energy Systems and Societal Change

High investment costs are a major impediment to the energetic refurbishment of residential buildings in Germany. Smart thermostats are a relatively inexpensive alternative. An IASS study shows that they are cost-effective for homes with a medium to low efficiency standard even when the realised energy savings are modest.

How can the energy transition be organized in a globally just way? Will developing countries struggle to transition to clean energy because they lack the financial and technical means? A new Policy Brief by the Institute for Advanced Sustainability Studies (IASS) focuses on the risks of an uneven transition and makes concrete proposals to prevent such risks.

In late September, the Kopernikus project ENavi presented their interactive simulation tools at the 28th meeting of the Committee on Sustainable Energy of the United Nations Economic Commission for Europe (UNECE) in Geneva. The tools can be used to demonstrate the impacts of measures to develop more sustainable transportation systems and expand renewable energy generation capacities.

The “Future Box: Carbon” developed by the IASS in cooperation with Berlin’s Futurium Museum offers school pupils an exciting and hands-on introduction to climate change and raw materials. This learning resource is suitable for use in classes from 8th Grade up and for all school types. The Future Box can be used in different subjects and will help to build awareness of sustainable development issues.

Ministerial representatives and experts from around the world met in Berlin over two days at the Climate Opportunity 2019 Conference to learn from each other about the co-benefits of transitions towards more sustainable energy systems. The conference also provided a space for the development of strategies to leverage the co-benefits of individual climate protection measures in the course of political decision-making processes.

On October 1st, 2019, representatives from EIT Climate-KIC, the Global CO2 Initiative, the Phoenix Initiative, and other interested stakeholders gathered in Brussels to discuss the future of Carbon Capture and Utilisation (CCU) assessment methodologies, a critical step in unlocking R&D and commercialisation efforts for this growing climate solution.

Europe has enough solar and wind resources to meet its electricity demand entirely from renewable sources. A new study by researchers at the Institute for Advanced Sustainability Studies (IASS) in Potsdam shows that many regions and municipalities could meet their electricity demand using electricity systems based exclusively on renewables. However, their development would exacerbate land use pressure around metropolitan areas and larger conurbations.

Even though electricity generated from solar and wind energy is becoming increasingly cost-competitive, the expansion of renewable energies continues to depend on policy support. When such support is lacking, setbacks to the energy transition can often result – as seen in the cases of the former pioneer countries Spain and the Czech Republic. What energy policy lessons can we learn from this? A study published in the journal Energy Policy makes recommendations for effective policy design.

Natural gas releases fewer harmful air pollutants and greenhouse gases than other fossil fuels. That’s why it is often seen as a bridge technology to a low-carbon future. A new study by the Institute for Advanced Sustainability Studies (IASS) has estimated emissions from shale gas production through fracking in Germany and the UK. It shows that CO2-eq. emissions would exceed the estimated current emissions from conventional gas production in Germany.

About 80 per cent of current CO2 emissions are caused by the member states of the G20. So it’s clear that they have a particular responsibility to reduce greenhouse gas emissions and encourage a shift to renewable energy. The leaders of these countries now need to act on that responsibility at the G20 Summit in Osaka on 28 and 29 June.

Many different technologies already exist for converting the greenhouse gas carbon dioxide (CO2) into products like construction materials and chemicals. But which of them can make a real contribution to climate protection? A new study commissioned by the European Commission provides answers.

Germany has committed to reducing its carbon emissions to 45 per cent of 1990 levels by 2030. There is a broad consensus that the decommissioning of the country’s coal-fired power plants is essential to achieving this goal. The shift to a more decentralised system of energy generation will, however, result in additional costs for society as a whole.

Digitisation can support the transition to a low-carbon energy system by facilitating the production, transportation and consumption of renewable energies. Digital technologies give consumers a role in determining when, where, and for what purpose energy is provided, how much energy can be saved, and what share of the energy mix renewables make up. From 13 to 17 May, early-career professionals from 16 different countries will meet with experts in Potsdam to discuss the challenges the transition to a sustainable energy system presents to politics, science, the private sector and civil society, and the role digitisation can play in the process.

The distribution grid is the backbone of the energy transition. In Germany, over 1.5 million decentralised energy systems now feed their output into the electricity grids managed by around 900 distribution system operators. Their management costs have increased considerably as a result. How do German distribution system operators cope with the challenges they face, and what can other countries learn from them? IASS researchers explored these questions in a representative survey. Their findings have been published in the journal Renewable Energy.

A clear majority of Germans across all income brackets, age groups and educational backgrounds still supports the Energiewende. Indeed, since the publication of the first Social Sustainability Barometer in 2017, there has been a notable rise in the number of people who view the energy transition as a broad societal task to which they personally want to contribute. However, there is growing criticism of the implementation of the energy transition by the German Government: Three quarters of respondents describe the process as “expensive”, while over half view it as “chaotic” and “unfair”.

Transforming Germany’s large power grid into a sustainable energy system is both a challenge and an opportunity. To succeed in this task, we need criteria that define sustainability and reflect society’s values and priorities. A research team in the Kopernikus Project “Energy Transition Navigation System | ENavi” has now developed a set of criteria that integrates a diverse range of perspectives.

Germany and Israel are pursuing ambitious goals in the expansion of renewable energies and the development of innovative technologies. A new fellowship programme aims to foster a lively exchange of ideas among professionals in both countries.

People are often apprehensive when they hear about plans to build a wind farm in their locality. They wonder how it will change the landscape. And whether the noise of the rotor blades will get on their nerves. People need information about the planned changes, but their direct involvement in the decision-making process is also important, because the expansion of wind energy depends on public acceptance. The Fachagentur Windenergie an Land and the IASS invited representatives from politics, the energy sector, and civil society to participate in the 3rd Workshop on Public Participation in the Development of Wind Farms on 15 and 16 January.

A new technology developed in a joint research project by scientists at Karlsruhe Institute of Technology (KIT) and the Institute of Advanced Sustainability Studies (IASS) promises to provide energy from natural gas without producing harmful CO2 emissions. The process converts natural gas, which consists primarily of methane, into hydrogen and solid carbon. The researchers have been recognized for their work with the Innovation Award of the German Gas Industry.

The days of Germany’s lignite-mining industry are numbered, that much is clear. The Coal Commission appointed by the Federal Government now has the job of planning how exactly the phaseout will proceed. One issue that is often overlooked in this context is the question of how the rehabilitation of former coal-mining sites is to be financed. A new IASS Discussion Paper examines the risks inherent in the existing financing practice and makes concrete proposals for changes.

A small footprint, more capacity and no losses - these are the main advantages of superconducting links for electricity transmission compared to conventional solutions. But how far is this new technology from deployment? Experts from the energy sector discussed the hurdles and chances at the final conference of the EU project Best Paths in Brussels.

Together with transmission system operators, partners from industry and science presented the results of ground-breaking research on a superconducting cable system at an international workshop on 5 July in La Spezia, Italy.

On 27 June the Federal Cabinet gave its stamp of approval to the 6th Energiewende Monitoring Report submitted by Economic Affairs Minister Peter Altmaier (CDU). In a statement on the report, the independent expert commission charged with observing the monitoring process has for the first time compiled indicators on public acceptance, drawing on the Social Sustainability Barometer for the German Energiewende. The Barometer, which monitors the social dimensions of the energy transition, was prepared for the first time in 2017 by the IASS in the context of the dynamis partnership.

The region of Lusatia in Eastern Germany is experiencing a structural transformation due to the dwindling significance of lignite. In a new research project, the IASS will investigate the changes taking place there. Karl Eugen Huthmacher from the Federal Ministry of Education and Research (BMBF) and IASS Scientific Director Patrizia Nanz presented the project at the Lusatia Dialogue on 25 June.

The international energy transition is already delivering numerous benefits, but it is also creating new inequalities. The risks posed by this transformation will impact especially on developing countries, which lack access to technologies and capital. What, then, can be done to ensure that these countries too can make the transition to a low-carbon economy? This question is the focus of a new project that will study the systemic impacts of the global energy transition.

What do citizens in France and Germany see as the key criteria for a fair energy transition? The Heinrich Böll Foundation France and the IASS presented two studies to 50 stakeholders from the policy community, business, science and civil society at an event in Brussels.

The Kopernikus projects present their research findings on the German Energiewende at the world’s largest academic conference in Austin.

To transport electricity effectively, a superconductor has to be inside an extremely well-insulated tube with an interior temperature of -200°C. Researchers at the IASS, the ESPCI engineering college in Paris, and French cable manufacturer Nexans have now developed a novel form of insulation that is compatible with the low temperatures and the high operating voltage of 320 kilovolts.

The Governor of Brandenburg and members of the state government came to the IASS on 12 December to discuss energy policy and climate protection. Together with the directors of the IASS and the Potsdam Institute for Climate Impact Research (PIK), they explored the idea of a Future Commission to ensure that Brandenburg’s energy transition is socially responsible and economically sustainable.

With Carbon Capture and Utilisation (CCU) technologies, carbon dioxide can be converted into products such as building materials, chemicals, and fuels. A new study investigates perceptions of carbon utilisation technologies in the UK and Germany.
