Final Reports of GJETC Study Program Available

The results of the 4 study reports, which build the core foundation for the GJETC’s recommendations, are now finalized.  The comprehensive study program deals with 4 topics, which the Council’s experts identified to be crucial for the energy transition in both countries.

Those 4 studies had been awarded to selected consortia of renowned German and Japanese research institutes in December 2016. After intensive discussions, stakeholder dialogues and in-depth research work and a thorough reviewing process, the 4 main studies can now be downloaded below. They will be a basis for the GJETC’s policy recommendations, providing the first comprehensive comparative analysis between Japan and Germany on these issues.

Study Topic 1: “Energy transition as a central building block of a future industrial policy – Comparison and analysis of long term energy transition scenarios

Title ST1
Key Findings

1. Both Japan and Germany have national energy transition targets and strategies. Additionally, the study compared long-term energy scenarios and the reasons behind differences.

2. A key difference is the expectations on future system costs of wind and photovoltaic (PV) energy. Germany expects high shares in energy supply due to low costs; Japan up to now expects higher costs and lower shares.

3. Japan’s island nature puts energy security as a top priority on the agenda and  perceives challenges from very high shares of fluctuating wind and PV generation.

Study Topic 2: “Strategic framework and socio-cultural aspects of the energy transition”

Title ST2

Key Findings

1. In both countries, energy policy is based on the principles of economic efficiency, energy security and environmental sustainability.

2. People in both countries have a favourable view of energy transition.

3. The study recommends a bilateral policy research dialogue between the two countries, complemented by a multi-stakeholder discussion with businesses as well as civil society and the research community.

Study Topic 3: “New allocation of roles and business segments of established and new participants in the energy sector currently and within a future electricity market design”

Title ST3
Key Findings

1. While Germany has longer and deeper experience in the liberalisation of electricity markets, both countries face similar challenges for electricity market design of the near future.
2. These concern, i.a., the flexibility options and costs for system integration of fluctuating wind and PV generation, but also coupling the power, heat, and transport sectors. Views on the future role of conventional power generation, particularly coal and nuclear, diverge.
3. New business and consumer concepts, such as prosumers, municipal utilities, and energy cooperatives, provide opportunities.

Study Topic 4: “Energy end-use efficiency potentials and policies and the development of energy service markets”

Title ST4
Key Findings

1. Both countries are already world-leading in energy productivity, also due to their existing policies.
2. Both countries have ambitious energy efficiency targets for the future based on still existing large potentials. Both have to strengthen their packages of energy efficiency policies to overcome barriers, including demand response.
3. While Germany could learn from Japan on energy efficiency in the transport sector, Japan could learn from Germany on energy-efficient buildings.

Outreach: Perspectives and First Results of the GJETC

Bilateral cooperation such as the GJETC can play an important role in mastering the challenges of the energy transition in the respective countries and facilitate the knowledge transfer worldwide with good examples. Since its foundation in May 2016, the German-Japanese Energy Transition Council (GJETC) has been working on strategic and systemic analysis to develop policy advice for new and long-term perspectives on the way to an ambitious energy transition. One main task of the GJETC is a study program using evidence-based scenarios and system analysis. A year after the council took up its work the preliminary results of the studies have been presented and discussed by the German and Japanese GJETC members under the title:

„German-Japanese dialogue: How far can the Energy transition go?“
Perspectives and First Results of the
German – Japanese Energy Transition Council (GJETC)


In his opening speech Atsushi Taketani (Deputy Commissioner for International Affairs, METI) underlined the importance of the systematic, scientific discussion about the comparability and differences in the evaluation of the approaches for the energy transition in both countries. After the input presentations by the GJETC Co-Chairs Prof. Peter Hennicke and Prof. Masakazu Toyoda more than 100 participants who followed the invitation of the GJETC witnessed a lively discussion about the results of the study program.


A short summary of the first results can be found in the report about the 3rd Council Meeting. Prof. Jun Arima, Dr. Hiroshi Okamoto, Franzjosef Schafhausen and Prof. Eicke Weber (photo 2, from l. to r.) discussed the feasibility of the energy transition before the different framework conditions of both countries.


First GJETC Study Results Presented in Tokyo

On September 4./5. the German-Japanese Energy Transition Council (GJETC) met again in Tokyo. The binational expert council came together for the third time to debate joint strategies for the energy transition. During the two-day session, the participants dissected the preliminary results of the studies that have been prepared in the past months. The meeting was followed by a stakeholder dialogue with German and Japanese company representatives who discussed the role of energy conservation services and technologies with the council members. In addition, the GJETC organized a public Outreach, in which the council members presented the first results of the studies to the public. Subsequently selected council members from both sides discussed the study results in regards to the question of the feasibility of the “Energiewende” in both countries.


Prof. Masakazu Toyoda and Prof. Dr. Peter Hennicke with the first results of the GJETC study program

In December 2016, a comprehensive study program of the GJETC on four study topics had been handed out to external consortia in Germany and Japan. Their task was to draw conclusions from a comparative analysis of key energy policy and economic issues in both countries. These serve as a basis for the GJETC to develop recommendations and proposals for solutions. The focus areas were (1) climate and resource-conserving long-term strategies (until 2050), (2) the overall economic and social preconditions of an energy transition, (3) electricity market design, and (4) the promotion of energy saving strategies. All studies have now been finished and analysed. The study (1) “Energy transition as a central building block of a future industrial policy”, for example, is a meta-analysis of energy transition scenarios covering the wide range of strategic options for both Japan and Germany. The scientists draw the conclusion that both countries need considerable changes compared to their recent energy system developments if they want to achieve their energy transition targets by 2030.

Prof Masakazu Toyoda, the Japanese co-chair of the GJETC, summarised the results presented: “The preliminary study results show that Japan and Germany have the possibility to substantially reduce  GHG emissions until 2050 through different approaches due to  the different national conditions. During our meeting in Tokyo, we discussed the results with a critical and constructive attitude in order to prepare our joint overall report.” Until the next meeting of the GJETC in Berlin on 14./15. February 2018, the members of the council will prepare their policy recommendations to the governments and the public of both countries based on the study results. The final reports of the study program will be published on the GJETC website.

The public event, organized by the GJETC on 6th September primarily addressed energy experts from administration staff, NGOs, and media representatives. During the event, the more than 100 participants had the chance to pose their questions to the co-chairs as well as experts of the GJETC directly and debate about the interim results. “With the event following the official council meeting, we wanted to reach all stakeholders and present the first results of the GJETC study program to a broader audience. If we want to accomplish an energy transition, it has to be supported by society as a whole,” said Prof Dr Peter Hennicke, German co-chair of the GJETC.
