| Abstract |
Using the new version of a database developed by the New Energy Foundation the country update report of direct uses of geothermal energy in Japan as of December 1999 is presented. Firstly, analyses are carried out for various aspects of direct uses of geothermal energy. Main results are as follows: 1) Installed thermal power is found to be 266.12 MWt, with the maximum in Hokkaido Pref. (91.71 MWt) for locality and in space heating including domestic hot water supply (136.70 MWt) for utilization type. 2) Thermal energy used is found to be 5399.59 TJ/yr, with the maximum in Hokkaido Pref. (1950.19 TJ/yr) for locality and in space heating including domestic hot water supply (2953.35 TJ/yr) for utilization type. Secondly, by comparing with other countries the economically severe condition for the use of geothermal energy as compared to fossil fuels in Japan is revealed statistically. |
