将下列段落翻译 The utilization of geothermal resource has increased rapidly during the last three decades. Geothermal resource has been produced commercially for over 80 years, and for four decades on the scale of hundreds of megawatts both for electricity generation and for direct use. In 2000 , geothermal resource has been identified in over 80 countries. There are quantified records of geothermal utilization in 58 countries in the world .An attempt was made to distinguish individual space heating from district heating, but this was often difficult as the individual country reports could not always make this distinction. Our best estimate is that, similar to WGC2005, 山 strict heating represents 86 % of the installed capacity and 88 % of the annual energy use .There is a category that covers a variety of uses, details of which are not frequently provided, but is known to include animal husbandry. Direct use of geothermal resources has expanded rapidly from space heating of single buildings to district heating, greenhouse heating, industrial usage, modern balneology and physical treatment facilities. Direct use projects generally use resource temperatures between 38 °C( 100 T ) and 149 °C( 300 T ) .
