Basic Guidelines Regarding the Installation of New Energy

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 surrounding environment not aggressive promoting for large size geothermal (binary) power plants necessary for new wells. -Promote mainly for the small size geothermal binary power plants with utilizing existing wellheads. 9 Citizens' awareness survey on the new energy
