5. Conclusion
   Regarding to the increasing rate of urban dwellers and also regarding to the new policies of the government for replacement resources of domestic energy consumption Iran has to utilize renewable energy in near future for compensate of energy demand and also for saving fossil fuels to export, because majority of our incomes comes from crude oil export.
   On the other hand environmental agreements force all the countries to use clean energy productivity and preventing of environmental pollution by modifying the old technologies to new environmental sound technologies so, despite a lot of suitable resources for geothermal energy productivity, initial basic data and also many expertise manpower and organizations, due to lacking of high-tech. instruments Iran has not been able to produce energy from these resources yet.
   Furthermore Iranian government has shown strong interesting in attraction of foreign investment in last years therefore regarding to good trade relationship between Iran and Japan there are many opportunities for Japanese companies to invest in geothermal field and transform of technology.
   Anyway, due to economic, environmental and new policies reasons it seems that energy production from geothermal fields in near future is inevitable so it is hoped that exploration drilling at Mt.Sabalan over the next months will lead directly to a commitment to develop the first geothermal power plant in Iran.
