As a natural resource in the earth, geothermal energy can be one of the renewable energy sources. “Geo” means “earth” and “thermal” means “heat”, so “geothermal energy” means “heat from the earth”.
For centuries, geothermal springs have been used for bathing and cooking. But only in the early 20th century, people have started to consider geothermal as a practical source of energy. Today it is used to produce electricity, to heat and cool buildings, as well as for other industrial purposes like fruit and vegetable growth.
The earth takes in solar energy. Geothermal energy becomes available when underground heat is moved by water that is heated when it passes through hot rocks, usually hundreds or thousands of feet deep. Most times, the rocks have lots of holes in them, this heat slowly comes out as forms of hot water and steam( 蒸汽).
Inside the earth, the temperature gets about 3 degrees higher as it gets 100 meters deeper. Water passing through hot rocks in the temperatures between 80℃ and 180℃ is able to produce enough heat to warm humans’ living space. Iceland, a cold country heats 90％ of the houses and buildings of its 320,000 people by using geothermal energy. Geothermal energy resources are widely discovered in China, making the country among the richest in geothermal energy in the world, and its highest geothermal power station in southwest China’s Tibet has been put into operation in 2018. In fact, the usable geothermal resources are found throughout the world and are used nowadays in 83 countries.
Compared with wind and solar energy, geothermal energy can not be affected by changes in the weather and seasons. We can always get energy from geothermal sources.
But like most other energy sources, geothermal energy also has a defect— it may present environmental problems. The surface of the ground may drop if hot groundwater is taken out without being replaced. In addition, the heated water can contain harmful materials. Apart from that, drilling far enough to make more energy sources costs lots of money.
Geothermal energy leads to new possibilities and its contribution to the world’s energy future is beyond our imagination.
