地热能作为一种低碳且稳定的能源，其开采和利用涉及多个数学学科的应用。地热梯度平均约为每100米2.5-3摄氏度，地表下约6000公里处的熔岩温度达到5000摄氏度1。地热发电需要一定的温度条件，最低要求为95摄氏度，当温度达到175摄氏度时能实现更高的电力输出1。加州Geysers地热发电厂的蒸汽温度约为235摄氏度，代表了现代地热发电的较高水平1。
地热能源的开发历史相对较短。第一座地热发电厂于1904年在意大利Larderello建成，之后日本和美国分别在1910年和1921年跟进1。进入21世纪，全球地热能源开发步伐明显加快：2005年至2010年间全球地热发电增长20%，同期开发地热资源的国家数增长52%1。冰岛自20世纪晚期以来成为地热能利用的世界领先者1。
尽管地热能具有显著优势，但其全球采用率仍然较低，主要受限于优质地热资源分布有限以及初期投资成本较高等因素1。
Geothermal energy represents a low-carbon power source with the potential for stable electricity generation, though its global adoption remains limited due to constraints such as the scarcity of high-quality geothermal resources and substantial upfront development costs.1 The Earth's geothermal gradient averages approximately 2.5 to 3 degrees Celsius per 100 meters of depth, while temperatures near the planet's core, approximately 6,000 kilometers below the surface, reach around 5,000 degrees Celsius.1
Harnessing geothermal energy for electricity generation requires minimum reservoir temperatures of 95 degrees Celsius, though output improves significantly at 175 degrees Celsius.1 The California Geysers facility operates with steam temperatures around 235 degrees Celsius.1 Geothermal power generation emerged in 1904 with the construction of the first geothermal power plant in Larderello, Italy, followed by installations in Japan in 1910 and the United States in 1921.1 Between 2005 and 2010, global geothermal electricity generation expanded by 20 percent, while the number of countries developing geothermal resources grew by 52 percent during the 2007 to 2010 period.1 Iceland has established itself as the world leader in geothermal energy utilization since the late twentieth century.1
