A new widespread crisis resulting from the reducation in oil supply had great impact not only upon regional energy demand but also upon regional economicstructures. Much more new energy will be demanded in the coming years.The strongest possibility for meeting such demands will be that of energy conservation through Soft Energ Paths by using regional energy; natural energy and biomass.The objective of the study is to estimate the effects on the regional development by utilization of Soft Energy. It will also cover an economic and environmental evaluation of Soft Energy.The area of inverstigation is the Morioka region of Iwate Prefecture, Japan. This region has not only abundant potential evergy; natural energy and biomass, but also a good prospect for regional development.The framework of the study involves the clarification of the social, economie, and industrial structures and the degree of potentiality of the Soft Energy, and the relationships between these structures and regional energy flow. A regional energ model utilizing Soft Energy will be constructed, and the economic and environmental effect of Soft Energy will be evaluated.The main results are as follows.The estimates of the energy demand in the Morioka region, analyzed by System Dynamics Method, are as follows. The energy demand of kerosene in the year 2000 is estimated to be 1.69 times greater than in 1980, gas (city gas and LPG) 1.55 times, electric light and electric power 1.45 times, heavy oil 1.42 times, and gasoline and light oil 1.26 times.The estimates of the energy conservation rates in the Morioka region by the Soft Energy are as follows. In 2000, 9.7% of the energy demand of kerosene is substituted by the Soft Energy.The estimates of the rate of favoring solar energy, geothermal energy, and biomass, based on Attitudinal Survey on the residents of Shizukuishi-cho, and analyzed by Latent Class Analysis Method, are as follows. The estimated rate of favoring geothermal energy represents a very high value of 88.3%. The rate of favoring biomass represents a low value of 57.0%.In Matsuo-mura (Matsukawa district), a power plant that generates 22, 000 kw of electricity utilizing geothermal energy was constructed in 1966, and also in Shizukuishi-cho (Kakkonta district), a power plant (50, 000 kw) was constructed in 1978.Vast volume of hot water is given from both plants.A project of utilizing hot water for multiple purpose is progressing in Shizukuishi-cho, and the effects on regional development, such as promoting the welfare of the people, and encouraging the industry and the agriculture, is expected.
