지열에너지 활용 방안연구

Since the high level of dependence on energy imports which has been more than 90% and the low level on new renewable energy in Korea, introduction of eco-friendly energy should be done to relieve these matters gradually. Geothermal energy, new renewable energy which supplies stable energy through maintaining constant temperature, is given attention for its highest efficiency, eco-friendliness and cost effectiveness in the existing air-conditioning technology by the U.S. EPA. In this thesis, consideration on the cost benefit side according to the replacement from existing fossil energy into geothermal energy system has been made on energy saving and economic feasibility side. Also, arrangement on the cost benefit side through tables and graphs considering the expense on installation and operation after changing construction has been made.
