地热同太阳能、潮汐能、风能等并称为取之不尽,用之不竭的绿色能源。地热不受地域限制,也不受外界环境条件所制约。不象太阳能受阴雨天所限,潮汐能受引潮力和风能受风力所制。科学家计算过,只要利用地壳上层一万米内1%的热量,就可保障人类相当长时间的能量需求。在美国科学促进协会年会上,布朗教授说:“在地球表面各处内部产生的热流是相当稳定的,平均每平方米有60毫瓦。但在某些温泉以及与火山有密切联系的地方,热流每平方米可达300毫瓦。”会上有位专家说:“从地热资源观点来看,地壳的绝大部分没有地热,常规地温则到处都有,如果把温度20～30℃的地下水,通过热泵提升到70℃,同样可以利
Geothermal, together with solar energy, tidal energy, wind energy and so on, is also called inexhaustible green energy. Geothermal is not subject to geographical restrictions, are not subject to external environmental conditions. Unlike solar rainy days, tidal tides can be tidal forces and wind energy by the wind system. Scientists have calculated that as long as the use of 1% of the upper crust 10% of the heat, you can protect human energy demand for a long time. At the annual meeting of the AAAS, Professor Brown said: ”The heat flux generated throughout the Earth’s surface is fairly stable with an average of 60 milliwatts per square meter, but in some hot springs and in volcanoes Place, heat flow up to 300 milliwatts per square meter. “” At an expert said: "From the geothermal resources point of view, the vast majority of the crust without geothermal, the conventional temperature is everywhere, if the temperature of 20 ~ 30 ℃ groundwater, heat pump to 70 ℃, the same can benefit
