World geothermal resources potential is estimated to be 189 EJ, which can take charge approximately a half of annual world energy consumption, considering the identified resources and supplies in USA and Iceland. Present annual use of geothermal energy, on the other hand, is only 1% of its potential, but still has 70% share among total new renewables. World-wide installed capacity of geothermal power generation reaches 8,900 MWe and 27,825 MWt for direct uses in 2005 which is almost two-fold increase over 2000. This increase is mainly due to exploding expansion of geothermal heat pump utilization; USA and western European countries lead these trends. Although geothermal heat pump distribution in Korea is still in its starting phase, comparing to Swiss achievement in terms of areal utilization sense, we expect to come up with national supply of over 600,000 toe in near future.
세계 지열에너지자원의 부존량은 미국과 아이슬랜드에서의 확인된 자원과 활용 현황을 고려할 때, 약 189 EJ에 이르며 이는 세계 연간 1차에너지 소비량의 절반가량을 공급할 수 있는 양이다. 이에 반해 현재의 공급량은 추정된 공급 가능량의 약 1%에 불과하나 아직까지는 기타 재생에너지 원에 의한 생산량의 70%를 차지하고 있다. 전세계의 지열발전설비는 2005년 현재 약 8,900 MWe에 이르며 직접이용량은 5년전에 비해 거의 두배 증가한 27,825 MWt 이다. 이러한 증가는 지열 열펌프의 폭발적인 보급 확대에 의한 것이며 미국 및 서유럽이 이를 주도하고 있다. 우리나라의 경우 아직도 전체적인 보급량은 미미하지만 스위스의 면적대비 보급량을 따라간다면 연간 600,000 toe 이상의 지열 열펌프 이용이 가능할 것으로 전망된다.
