There are some very deep sources of radiogenic heat with geothermal power potential, like the Cooper Basin in Australia which lies 4.2 kilometres or over 2.5 miles underground. In other places in the world heat is harvested very close to the surface like The Geysers, a geothermal field in California.
What else can I help you with?
How does a geothermal power plant get energy?
A geothermal power plant harnesses energy from the Earth's heat stored beneath the surface. The plant uses this heat to generate steam by pumping water into underground reservoirs, which drives turbines to produce electricity.
What heats the water in the deep underground reservoirs used for geothermal power?
The water in deep underground reservoirs used for geothermal power is heated by the Earth's internal heat. This heat is generated by the decay of radioactive elements and residual heat from the planet's formation. The water is heated to high temperatures before it is brought to the surface to generate electricity.
Is geothermal energy intermittent?
Geothermal energy. Heat from deep under the ground remains constant, not intermittent, so geothermal plants that drill deep into the hot layers will have constant power.Hydro and wave energy is also constant. Other alternative energy sources (solar, wind, tides) are all intermittent, as power is only available at particular times, and so need energy storage.
What is heat from the earth called?
Geothermal. it is called geothermal. Geothermal thermal energy is what you get when water is pumped through pipes deep under the crust and the water is heated creating steam that travels up the pipe and then is transformed into geothermal heat and energy.
What is one drawback of drilling geothermal wells?
One drawback of drilling geothermal wells is the high upfront costs associated with drilling deep into the Earth's crust to access the geothermal resources. Additionally, there can be challenges in finding suitable locations with sufficient heat and permeability to support geothermal power generation.

How important will geothermal energy be in the future?
It is difficult to say. There are many forms of renewable energy (solar, wind, hydro, tidal and wave, geothermal among others) and some are easier to set up than geothermal. A geothermal power plant requires two shafts drilled deep into the earth to get hot water and steam for the plant, and wind and solar may be an easier answer for the future.
Are hot springs and geysers examples of geothermal activity?
Yes, this is true. Geothermal power is the only form of renewable energy that does not originally come from the sun. Geothermal power uses the heat from deep inside the earth.
How is geothermal energy an alternative energy?
Geothermal energy is a renewable source of energy because it can be re-used, unlike fossil fuels. Geo- means earth, and -thermal means heat. A power plant will use the heat energy found deep in the earth to create electricity. Since the thermal energy of the earth will never go away, geothermal energy is a renewable source.

What fuel will you use when fossil fuel runs out?
Many people would use solar power because solar power is quite common but some people will use wind power depending on the location of where they lifeGeothermal it is overlooked. In active areas it gets hot down there. Some hot spots can boil water 200 feet deep. But it is being ignored because the Oil and power companies are afraid of it. Anyone can make their own power 24/7 with it. Or nearly everyone. Between that and solar and wind we do not need oil.The problem in Japan has brought the attention to geothermal and they are building a plant. Places like Yellowstone and near volcano can generate enough power to power cities or states. Iceland gets most of it's power from geothermal. And Geyserville in California has a geothermal plant that is on a hot spot that boils the water. Hawaii cold generate all their power by geothermal if they wanted.

Other alternative energy sources (solar, wind, tides) are all intermittent, as power is only available at particular times, and so need energy storage.
How does steam create geothermal power?
It's the other way round. Geothermal power creates steam. Water is pumped deep underground where it is forced through layers of very hot rock. The steam produced is pumped up another shaft where it is used to spin a turbine, generating electricity.
What is a geothermal power plant?
A geo thermal power plant uses the heat provided deep below the earths surface combined with water to create super heated steam, which then powers a turbine to produce electricity.Geothermal plant is a power plant using thermal energy from underground to boil the water and pass through turbine producing electricity.

Additionally, there can be challenges in finding suitable locations with sufficient heat and permeability to support geothermal power generation.
Temperature is the biggest challenge in using what type of energy source?
Temperature is a major challenge in using geothermal energy sources. The efficiency and productivity of geothermal power plants are highly dependent on the availability of high-temperature resources deep underground. Low-temperature geothermal sources are less efficient and limit the scale of power generation.
