"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 use of heat generated by the Earth's core to generate electrical energy.
"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.
