  1. What can Japan do to increase the use of geothermal energy in the future? Number : 11780029 Name : Osamu Urushisaki

  2. The merit of geothermal energy • Little of CO2 emissions • Height of an operating ratio The amount of CO2 emission (㎏/MW-hr.) 1/6 time The operating ratio (％) CoalOilNatural gasHeat of the earth Heat of the earth Atomic powerCoal fire power Wind force Sunlight

  3. The demerit of geothermal energy • Discharge of H2S (hydrogen sulfide ) • The abandonment method of geothermal fluid • There is also a possibility that heat may finally be exhausted in some geothermal zones • A setting position is limited

  4. United States The No.1 geothermal energy development area of the world • The country which exploits geothermal energy most in the world • There are 77 geothermal power plants • Boiling water is used in farmland or urban areas

  5. Iceland • About 100% renewal energy • Power generation(water-power:70%, geothermal:30%) • There are 25 or more active volcanoes and many hot springs • A capital is world leading "a town with clean air " • Geothermal water is used at various places

  6. The way to the expand in Japan A problem of Japan • Construction cost is high • There is regulation of national parks • Understanding of the hot spring industry cannot be obtained If it is solvable, Japan could ・・・ United States ⇒ A large-scale geothermal power plant Exploitation of natural power sources is high ⇒ Iceland

  7. Thank you for your attention!
