Theresa Wildgrube, M.Sc.

Theresa Wildgrube

has been working as a Research Associate and as a doctoral candidate at the EWI since 2016. In consulting projects for clients from the industry and public sectors, she has examined, e.g,. alternative financing mechanisms for the German Renewable Energy Sources Act (EEG). She has advised, among others, the German Ministry for Economic Affairs and Energy (BMWi), the German Energy Agency (dena) and Ecofys. Her research focus lies in the field of decarbonization in the industry sector as well as climate and energy politics. Before joining EWI, Theresa Wildgrube worked as a public policy consultant on energy and climate policies at Fundación IDEA in Mexico City. She studied Economics and Management Science at HU Berlin as well as International Relations at TU Dresden (Germany) and the University of New England (Armidale, Australia).

dena-Leitstudie Integrierte Energiewende (dena Study on Integrated Energy Transition)

The dena-Leitstudie Integrierte Energiewende develops and compares transformation pathes for the energy system in Germany with the objective to attain the climate-political goals by 2050. It pursues an innovative cross-sector scenario approach. At the same time, it is based on the branch knowledge of more than 60 partners from all relevant sectors and on the continuuos exchange with important actors from politics, society and science. The objective is to give impulses for designing the energy system by 2050. ewi ER&S is the main scientific advisor to the study. The central results of the study say that Germany will be able to attain its goals to reduce greenhouse gas emissions by 80 as well as by 95 % up to the year 2050 if the strains in all sectors are increased. Therefore, the roll-out and system integration of renewable energy sources must be forced, the end energy consumption has to be reduced by extensive energy efficiency efforts, and synthetic regenerative energy sources must be used on a big scale. A broad mix of technologies and energy sources makes the transformation of the energy system more cost-efficient than a fortified use of electricity-based applications.

Brief assessment of alternatives for financing the German Renewable Energy Act (EEG)

ewi ER&S and FiFo Cologne assess three extreme cases of financing alternatives for the EEG: a kW-based levy on electricity, a carbon tax as well as financing from the federal budget. All options improve the competitiveness of electricity and incentivize sector coupling.

Gebäudestudie – Szenarien für eine marktwirtschaftliche Klima- und Ressourcenschutzpolitik 2050 im Gebäudesektor

The Buildings Study (Gebäudestudie), initiated by the members of the Allianz für Gebäude-Energie-Effizienz (geea), provides an economic analysis of the buildings sector. It investigates how the transformation of the buildings sector can be accomplished by an interplay of building shell, installation technology and a changed energy production, to reach an attainment of reducing greenhouse gases by 80% and by 95%. The study was created in the context of the dena-Leitstudie Integrierte Energiewende (Integrated Energy Transition). ewi ER&S is the main economic reviewer of the study, cooperating with FIW and ITG as technological reviewers.

Economic Impacts of a German Coal Phase-Out on the Power Markets in Germany and the EU

With the study „Economic Impacts of a German Coal Phase-Out on the Power Markets in Germany and the EU“, ewi ER&S takes up a proposal made by the German think tank Agora Energiewende in January 2016 concerning a coal phase-out in Germany. The proposal suggests a combination of two policy measures for the power sector. First, it encourages an early decommissioning of the German coal-fired power plants up to 2040 and, secondly, a retirement of emission allowances from the European emissions trading system in the amount of the mitigated CO2 emissions resulting from the coal phase-out. Based on ewi’s power market model DIMENSION, the study investigates the additional costs and distributional effects of this double-measure for the German and European power markets. The coal phase-out is assessed by economic theory and its projected costs are compared to the amount of CO2 abated.
