Summary
Entrusted Work Concerning the Development and Disclosure of Basic Zoning
Information Concerning Renewable Energies and Study on Actual Performance
Pertaining to the Introduction of Renewable Energy Systems (FY 2016)
The introduction of renewable energies is important not only as a countermeasure for global
warming but also from such viewpoints as establishing energy security, developing autonomousand scattered energy systems and creating new industries and jobs. For this reason, in an effort
to create basic data for the introduction and spread of renewable energies in the coming years,
the Ministry of the Environment (MoE) conducted the Study on the Potential for the
Introduction of Renewable Energies in FY 2009 and FY 2010 and the Development of Basic
Zoning Information in FY 2011 through FY 2015, thereby estimating the abundance as well as
introduction potential of renewable energies (non-residential use of PV power, use of PV for
individual buildings, wind power, small and medium-scale hydropower, geothermal heat, solar
heat and underground heat) and their possible introduction amounts by different scenarios anddeveloping basic zoning information.
In this work, the information so far developed regarding renewable energies is rearranged forits disclosure on the MoE Home Page. The study also examined a method to study the actual
performance pertaining to the introduction of renewable energy systems so that the information
obtained by such a survey can be effectively used in the future. By doing so, the study aims atenhancing the understanding and convenience of people, local public entities, business
operators, etc. regarding the use and introduction potential of renewable energies, promoting
the introduction of renewable energies and contributing to countermeasures for global warming.

Development of Basic Zoning Information on the Use of Underground Heat (HeatPump)“Information on a method to use deep underground heat”, “information related to a hydrologicalenvironment map” and “information related to the study on abundance of underground waterin FY 2009” was sorted to provide reference data for examination of the introduction of a heatpump to use underground heat. In regard to “information on a method to use deep undergroundheat”, GIS data was arranged featuring “the scope of applicability of a method to use deep
underground heat” and “the relevant depth to the deep underground”. In addition, information
on projects to which a method to use deep underground heat would be applicable was sorted.
For “a hydrological environment map”, GIS data was arranged featuring “the plan by depth ofhydrological head” and “the planar distribution of underground temperature”. In regard to“information related to the study on abundance of underground water in FY 2009”, GIS data
was arranged featuring “the estimated underground table by 1 km mesh (Excel data)” alongwith PDF data for “a report for the optimization of underground water utilization”.

4. Study on Actual Performance of Introducing Renewable Energies(1) Examination of Basic Principles for Study on Actual Performance of Introducing
Renewable Energies and Study Method
The basic principles for the study on the actual performance of introducing renewable energies
and the study method were examined, taking the opinions expressed by advisors at the general
meeting into consideration.
(2) Examination of Measures, etc. to Utilize the Study Results
Measures (tentative) to utilize the results of the study on the actual performance of introducing
renewable energies were examined from the viewpoint of the central government, prefectural
governments, municipal authorities, business operators and people as well as from theviewpoint of the medium and long-term utilization of the said results.

(3) Examination of Renewable Energy Systems Subject to the Study
Self-consumption type renewable energy systems which were involved in private power
generation and utilization, the subject matters of the main study, were defined and the system
requirements were set.
(4) Research on Existing Literature
The existing literature pertaining to the actual introduction of various renewable energy systems
was obtained and sorted to determine how much of such information could be obtained. In
addition, the volume of introduction of renewable energy systems utilizing a feed-in-tariff (FIT)
was sorted by municipality. Following comments in interviews with knowledgeable persons
that a list of delivery destinations could be obtained from private business operators selling
products pertaining to self-consumption type renewable energy systems, a list was createdcontaining information on business operators dealing with various renewable energies.
(5) Implementation of a Preliminary Study
In preparation for the main study scheduled to be conducted in the next fiscal year onwards, a
study method was examined and planned. A preliminary study (questionnaire survey) was thenconducted targeting prefectural governments and municipal authorities (total of 282 local public
entities) for the purpose of verifying the relevance and effectiveness of the study method andstudy contents. Having discovered certain issues through this questionnaire survey, possible
remedial measures to be adopted in the main study were examined.
(6) Understanding of Actual State of Introduction and Conditions for Introduction of
Renewable Energies for Private Power Generation and Heat Utilization
Knowledgeable persons were interviewed on self-consumption type renewable energy systems
used for photovoltaic power generation or the utilization of wood-based biomass heat so thatgeographical areas and building types offering strong potential for the dissemination of selfconsumption type renewable energy systems in the coming years could be identified andvisualized. Information pertaining to the actual state of introduction and conditions for the
introduction of these systems was then sorted.
