which involve drilling into the earth’s surface to reach deeper geothermal resources, can allow broader access to geothermal energy. Geothermal plants also differ in terms of the technology they use to convert the resource to electricity (direct steam, flash, or binary) and the type of cooling technology they use (water-cooled and air-cooled). 
鑽探地表以獲取更深層地熱資源的開採方式，可以使更多人獲得地熱能。地熱發電廠在將地熱資源轉化為電能的技術（直接蒸汽式、閃蒸式或雙循環式）和冷卻技術（水冷式和空冷式）方面也存在差異。
