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.
Do you think Geothermal energy is a renewable resource Why or why not what are the benefits of using this energy to power homes and businesses can you think of any consequences to communities or the surrounding environment?
Why is geothermal energy a renewable resource? 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 renewable and reliable?
Geothermal provides a reliable source of energy as
compared to other renewable resources such as wind and solar power. This is because the resource is always available to be tapped into, unlike with wind or solar energy.
How can geothermal energy be used as a renewable resource?
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.
Is geothermal energy renewable or flow?
Geothermal energy is heat that is generated within the Earth. (Geo means “earth,” and thermal means “heat” in Greek.) It is
a renewable resource
that can be harvested for human use. About 2,900 kilometers (1,800 miles) below the Earth’s crust, or surface, is the hottest part of our planet: the core.
What country is the largest producer of geothermal energy?

Can we run out of geothermal energy?
Geothermal energy is a renewable energy and
will never deplete
. Abundant geothermal energy will be available for as long as the Earth exists.
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 3 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.
What are the major applications of geothermal energy?
Geothermal hot water can be used for many applications that require heat. Its current uses include
heating buildings
(either individually or whole towns), raising plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes, such as pasteurizing milk.
Where is geothermal energy best used?
Most of the geothermal power plants in the United States are in western states and Hawaii, where geothermal energy resources are close to the earth’s surface.
California
generates the most electricity from geothermal energy.
How expensive is geothermal energy?
On average, a homeowner can expect total expenses to reach
between $18,000 to $30,000
on geothermal heating and cooling cost. This cost would cover a complete geothermal installation. The price can range from $30,000 to $45,000 with high-end ground-source heat pump systems for large homes.

What’s wrong with geothermal energy?
Cons of geothermal energy: generates waste, reservoirs require proper management, it’s location-specific, has high initial cost, and can cause
earthquakes
in extreme cases. Geothermal has the potential to become a major global energy source, but is held back by its high upfront costs.
