Ending Subsidies Slows the Growth of Wind and Solar Power

Falling prices for renewables such as wind and solar are prompting policymakers at the national and European levels to consider phasing out support mechanisms. In a new scientific study, we show that discontinuing these instruments could have negative effects on the growth of these renewables. We arrived at this conclusion with the aid of a model in which we have integrated empirical investor preferences for the first time.

German Election

The Desire for Continuity in Change

The SPD's success in the Bundestag elections is surprising, even though the polls predicted this outcome in the days and weeks leading up to the election. In July, polls by infratest-dimap and the Elections Research Group suggested that the SPD could win as little as 15-16 percent of the vote and a neck-and-neck race between the CDU/CSU and the Greens seemed likely. But things turned out differently, and now the Social Democrats are the victors, even though the SPD's 25 percent win is a far cry from the results returned by previous SPD chancellors.

The Siemens-Nigeria Electrification Roadmap Partnership: After Two Years, Where Does It Stand?

The Nigerian government and German energy company Siemens AG signed the Nigerian Electrification Roadmap (NER) partnership, also known as the Presidential Power Initiative (PPI) in 2019. The Roadmap contains technical and commercial proposals for financing, implementing, and executing projects to revive the Nigerian power sector and manage Nigeria’s future electricity requirements.

New Technology, Equity and the Law of the Sea

Advancements in new technologies open up new ocean industries and possibilities to explore the ocean. Some of these new technologies, such as swarms of underwater mini robots to map the seafloor or sensors on automated underwater vehicles, assist scientists in their work and produce growing quantities of ocean data.

The EEG as the core instrument in German climate policy

Some German political parties and economists suggest ending the Renewable Energy Sources Act (EEG) surcharge in the power bill and instead financing renewables through the carbon tax. While the recent carbon pricing debate has focused on equity and political feasibility, it has neglected the elephant in the room: how would this change affect Germany’s ability to meet the 2030 climate goals? Here, we show that this refinancing would put climate goals at risk. Purely market-based renewables are not yet viable, the change could therefore slow down their already sluggish deployment. We thus argue that the EEG remains the quintessential instrument for German climate policy in the coming decade.

A win-win for cyclists – measuring effects of the transport transition on air quality

Recently, the team of the “Climate Change and Air Pollution” (ClimPol) project published an article in Environmental Research Letters detailing the results of a measurement campaign conducted along Kottbusser Damm in Berlin-Kreuzberg. In short, we found that the implementation of a protected pop-up bike-lane along the street reduced the amount of air pollution cyclists were exposed to by 22%. On its own this is a significant, but perhaps not unexpected result. However, to set these results in their proper context, first we need to rewind back to 2018.

Out there, it’s different

It is not uncommon for the German name of the IASS to evoke confused looks on people’s faces: Institut für transformative Nachhaltigkeitsforschung – “I’m sorry, but what is ‘transformative’ supposed to mean, and what is ‘transformative research’?” A comprehensive yet straightforward answer is given in Jan Freihardt’s book “Draußen ist es anders” (“Out there, it’s different”), subtitled “Treading new paths towards a science of transition”.

Energy Access, Water, Sanitation, and Food Security in Rural Areas: Insights from Rwanda

What kind of help do remote rural villages in developing countries need to sustainably improve their infrastructure? What is the state of electricity supply and services, the availability and quality of cooking solutions, and the quality of water access in these settlements? Is there a nexus between access to basic services and nutrition in these areas? And, if a project is implemented, how can progress made at the household level be monitored, reported, and evaluated? These questions are at the heart of the project “Action-Based & Impact-Driven Research: Establishing Collaborative Frameworks for Researchers, Impact Makers, and Sustainable Entrepreneurs (IMPACT-R).”

Structures in Transformation – Lusatia in Focus

Since 2020 artist and photographer Sven Gatter has been documenting traces of decay and renewal in Lower Lusatia that are simultaneously new beginnings and occasions for discourse. He is now bringing the results of this work together in the artist's book "ECHO TEKTUR. Ruins and Models". IASS researcher Johannes Staemmler has penned a contribution to this publication, which we publish here in an abridged version. Sven Gatter's works will be shown at Brandenburg’s State Museum of Modern Art from 10 September through to 21 November 2021.
