How does geothermal energy production work?

geothermal energy production works by extracting energy from heat deep inside the ground. In some places, such as Island Islands, Philippines and Japan, geothermal hot springs are common, allowing easily accessible energy. In other places there are only more than a kilometer (1.6 km) under the surface, which makes geothermal energy impractical extraction. Holes dug to this level anywhere can usually be used to produce geothermal energy. However, geothermal energy production is not the main energy source around the world, which accounts for only about 0.1% of global force or the capacity of approximately 100 gigawatts. Geothermal energy is used only by countries in the Philippines and Iceland, where they make up 15-20% of Generation's electrical organizations. The heat causes the secondary fluid to flash steam, which controls the turbines that produce electricity. The fluid is then re -end and is used for multiple cycles. The secondary fluid pressure is usually relatively high, around 500 dogs.

geothermal energy of hot dry rocks is another type of geothermal energy production; This method pumps water deep into the ground and puts it in contact with a hot dry rock that gives the method its name. The rock warms up water, which is then exhausted and used either directly by steam turbines or draws binary. These plants, also known as improved geothermal systems, have a lifetime of about 20 to 30 years before the rock cools too much to make the plant economical. Full heat is recovering in 50-100 years.

Another type of geothermal energy production is the flashes of steam plants. These plants pull hot, high -pressure water from deep on the ground up to the tanks, where the decrease in pressure causes water to break into steam, which is then used to turn turbines. One of the oldest types is direct heat that pulls hot water from the proximity of the earth's surface into the pipeline for use to thermal buildings, thermal inODY for fish breeding, growing plants in greenhouses, pasteurizing milk, etc. It works only in areas where enough hot water is available near the surface.
