"The geothermal energy is thermal energy in the Earth's crust. It combines energy from the formation of the planet and from radioactive decay."
The energy generated by heat from the Earth's interior.
Geothermal Energy: This refers to the heat that is generated from the Earth's core, which can be harnessed and used for energy production.
Geothermal Resources: This refers to the various types of geothermal resources, including hydrothermal, petrothermal, and enhanced geothermal systems.
Geothermal Power Plant: This refers to the facilities that are used to generate electricity from geothermal resources.
Geothermal Heat Pump: This refers to the system that uses the Earth's heat to provide heating and cooling.
Geothermal Direct Use: This refers to the various applications of geothermal energy, including heating homes and buildings, drying crops, and producing hot water.
Geothermal Exploration: This refers to the techniques and methods used to identify and evaluate geothermal resources.
Geothermal Reservoir Modeling: This refers to the process of developing models that simulate the behavior of geothermal reservoirs.
Geothermal Economics: This refers to the economic factors that influence the development and use of geothermal energy, including cost, availability, and regulatory environment.
Geothermal Policy: This refers to the various regulations and policies that govern the development and use of geothermal energy.
Geothermal Sustainability: This refers to the ability of geothermal energy to meet the needs of the present without compromising the ability of future generations to meet their own needs.
Hydrothermal energy: This is the most common type of geothermal energy, and it refers to steam and hot water that is extracted from underground reservoirs. These reservoirs are typically located near active volcanoes, geysers, or hot springs. Hydrothermal energy is used to generate electricity or heat buildings.
Enhanced geothermal systems (EGS): This type of geothermal energy involves creating an artificial reservoir by drilling deep into the earth and injecting water into the rock. The heated water is then brought back up to the surface, where it can be used to generate electricity.
Geothermal direct use: In areas where there are hot underground water resources, geothermal energy can be directly used for heating buildings or homes, as well as for geothermally-driven agriculture.
Geothermal heat pumps: This type of geothermal energy is used to heat or cool buildings by taking advantage of the stable temperatures found underground. The heat pump uses the ground as a heat source in the winter and a heat sink in the summer, reducing the need for traditional heating and cooling systems.
Binary cycle power plants: This type of geothermal energy utilizes the heat from low-temperature geothermal resources to vaporize a fluid with a low boiling point, such as a hydrocarbon or ammonia. The vapor energizes a turbine, which generates electricity.
Flash power plants: This type of geothermal energy is used to produce electricity by bringing high-pressure hot water to the surface, where it is rapidly depressurized and boiled, resulting in the formation of steam that drives a turbine.
Co-produced geothermal energy: This type of geothermal energy uses the hot water that is produced as a byproduct of oil, gas, and other energy production processes. The hot water is extracted and used to generate electricity or heat buildings.
Magma-derived geothermal energy: This type of geothermal energy is derived from the extremely hot, molten rock that exists deep beneath the Earth's surface. This energy is currently not feasible for use on a large scale.
Geothermal aquaculture: This type of geothermal energy is used in fish and shrimp farming, where hot water is used to maintain a warm and stable environment for aquatic life.
Geothermal greenhouse heating: This type of geothermal energy is used to create a warm climate for year-round greenhouse farming by burying pipes filled with hot water or steam beneath the ground, which releases heat as it cools.
"Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since Roman times."
"Geothermal power, (generation of electricity from geothermal energy), has been used since the 20th century."
"Unlike wind and solar energy, geothermal plants produce power at a constant rate, without regard to weather conditions."
"Most extraction occurs in areas near tectonic plate boundaries."
"The cost of generating geothermal power decreased by 25% during the 1980s and 1990s."
"Technological advances continued to reduce costs and thereby expand the amount of viable resources."
"In 2021, the U.S. Department of Energy estimated that power from a plant 'built today' costs about $0.05/kWh."
"In 2019, 13,900 megawatts (MW) of geothermal power was available worldwide."
"An additional 28 gigawatts provided heat for district heating, space heating, spas, industrial processes, desalination, and agricultural applications as of 2010."
"As of 2019, the industry employed about 100 thousand people."
"Pilot programs like EWEB's customer opt-in Green Power Program suggest that customers would be willing to pay a little more for renewable energy." Please note that the paragraph provided does not contain all the information required to answer all twenty study questions.
