“Geothermal energy is renewable because the Earth has retained a huge amount of the heat energy that was generated during formation of the planet . In addition, heat is continuously produced by decay of radioactive elements within the Earth.
Which statement explains why geothermal energy is a renewable resource?
“Geothermal energy is renewable because the Earth has retained a huge amount of the heat energy that was generated during formation of the planet . In addition, heat is continuously produced by decay of radioactive elements within the Earth.
How is geothermal energy renewable?
What is geothermal energy? Geothermal energy is heat within the earth. ... Geothermal energy is a renewable energy source because heat is continuously produced inside the earth . People use geothermal heat for bathing, to heat buildings, and to generate electricity.
Which of the following best describes geothermal energy source?
Geothermal energy is the heat that comes from the sub-surface of the earth . It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma.
Which of the following best describes renewable energy?
The most common definition is that renewable energy is from an energy resource that is replaced rapidly by a natural process such as power generated from the sun or from the wind . ... Most renewable forms of energy, other than geothermal and tidal power, ultimately come from the Sun.
Can we use geothermal energy in our daily life?
Low-temperature geothermal energy can be used for heating greenhouses, homes, fisheries, and industrial processes. Low-temperature energy is most efficient when used for heating, although it can sometimes be used to generate electricity. ... The low-temperature geothermal energy also supplies heat to homes and businesses.
Why is geothermal energy not always a renewable source?
Answer: Because its source is the almost unlimited amount of heat generated by the Earth’s core . Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.
Is geothermal energy bad for the environment?
The environmental impact of geothermal energy is minimal , especially compared to fossil fuel power plants. When sited and constructed carefully, geothermal power plants can be a reliable source of renewable and environmentally-friendly electricity.
What is the main source of geothermal energy?
Geothermal energy is produced by the heat of Earth’s molten interior . This energy is harnessed to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator.
What are the major applications of geothermal energy?
- Space heating and cooling.
- Generation of electrical power.
- Industrial process heat.
- Other applications includes desalination of water, heavy water production, extraction of minerals from geothermal fluids, timber seasoning etc.
What is example of geothermal?
A Geyser is an example of Geothermal energy. Hot springs, lava, and fumaroles are natural examples of geothermal energy. Geothermal power is currently more common in homes and businesses, using geothermal heat pumps to control the temperature in the building.
What are the three main uses of geothermal energy?
Geothermal energy is used in three main ways: direct use, power generation, and ground source heating and cooling : Direct Use: The hot water in geothermal reservoirs produces heat and steam, which can be directly used for multiple purposes. In the past, hot springs were directly used for bathing and cleaning purposes.
How many countries use geothermal energy?
Geothermal electricity generation is currently used in 26 countries , while geothermal heating is in use in 70 countries. As of 2019, worldwide geothermal power capacity amounts to 15.4 gigawatts (GW), of which 23.86 percent or 3.68 GW are installed in the United States.
What are examples of renewable?
- Solar energy.
- Wind energy.
- Geothermal energy.
- Hydropower.
- Bioenergy.
What type of energy is renewable?
- Solar energy.
- Wind energy.
- Hydro energy.
- Tidal energy.
- Geothermal energy.
- Biomass energy.
What type of renewable energy comes from burning plants?
Biomass is an incredibly versatile substance, able to produce energy through being burned directly, converted into liquid biofuels or harvested as a gas from landfills or anaerobic digesters. Its own source of energy comes from the sun, and as plant matter can be regrown relatively quickly, it is classed as renewable.
