＊Formation of Beppu hot spring：50K years＊History of Beppu Onsen：Back to 8 Century＊Source of Onsen is rain water.＊Subsurface rain water turn over every 50 years.＊ The resources of the onsen is hot water type of the chloride spring places under the Tsurumi volcanic group. （Temp.: 250～300℃、Ｃl:1400～1600ppm）

３ Features of Beppu Hot Spring(Onsen) Villages ②

■The place of the hot spring origin in Japan!

-In 1919, drilling for the geothermal(113℃) utilization succeeded in Beppu City.

-In 1925, First geothermal generation(1.3kW) started in Japan.

■Local people opposed to the geothermal development in the past!

-In 1981, the opposition movement by Beppu local people let Idemitsu withdrew the application which had applied drilling plans for the geothermal power plant to Oita Pref..

７ New supports for the geothermal development（２０１５）

Basic Objective 1: Installation of new energy attuned with the environment⇒ The approaches focused on harmonizing with the environment.

Basic Objective 2: Contribution to the tourism industry⇒ Revitalizing onsen / tourism industry.

Basic Objective 3: Installation of local reduction type new energy⇒ Revitalizing community by returning the merits.

Basic Objective 4: Secure energy in times of disaster⇒ Striving for a community with strong resistance against disasters.

■ Policy for the geothermal power

-Promote only exist wellheads and projects with no effects to the surroundingenvironment not aggressive promoting for large size geothermal (binary) powerplants necessary for new wells.

-Promote mainly for the small size geothermal binary power plants with utilizingexisting wellheads.

Ｑ２） What approaches citizens require to the city for the utilizing onsen energy?

％

【The reason for enacting】１）The requests increased for development of new energy system from in/outside of the City Office.

２）Arising the geothermal developers with slight awareness to the regulations and laws.３）More importance of mutual understanding between new energy developers and local peoples.

11 Act Regarding Preliminary Procedures of Local New Energy Installation of Beppu City（２０１４） and Ordinance

【Occur another issues】１）Rushing large size equity entry２）Affect to the environment３）Worsen the local emotion

４）Over utilization of hot water?５）Over yielding of springs?

Act Regarding Preliminary Procedures of Local New Energy Installation

Some limitations for guidance.

【View of City Office】-In regard to the installing the geothermal facilities, it is necessary for utilizing sustainably and orderly with proper guidance and supervision by administration sector in terms of hot spring and living environment protection, promoting local understanding, and local contribution.

Establishing the strict ordinance in order to promote installation of geothermal power orderly.
