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. The focus was set on (1) long-term energy transition scenarios, (2) the overall economic and social preconditions of an energy transition, (3) electricity market design, and (4) the promotion of energy saving strategies.

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.
