Abstract:
Despite being one of the cheapest and most reliable sources of renewable energy, there is no harnessing of heat from the ground outside of Iceland. In this video, we are going to learn what is Geothermal energy, its advantages, and disadvantages, what are those challenges that stop us from getting energy from Earth, and much more. So be sure to watch until the end.
What is geothermal energy?
Geothermal energy is heat in the earth. The word geothermal comes from the Greek words 'geo' which means earth and 'therm' means heat. Geothermal energy is a renewable energy source because heat is continuously produced in the earth. People use geothermal energy to bathe, heat buildings, and generate electricity.
How does it work?
Humans can harvest geothermal energy by:
-Geothermal power plants, using heat from within the earth to generate steam to generate electricity.
And,
-Geothermal heat pumps, using heat near the earth's surface to heat water or heat buildings.
Geothermal power plant
In geothermal power plants, wells are drilled 1 or 2 miles into the earth to pump steam or hot water to the surface. You'll likely find one of these power stations in an area with lots of hot springs, geysers, or volcanic activity, as these are places where the earth is extremely hot just beneath its surface.
Now, let's break down its working step-by-step:
-Hot water is pumped from below through a high-pressure well.
-When the water reaches the surface, the pressure drops, causing the water to turn into steam.
-The steam spins a turbine, which is connected to a generator that produces electricity.
-The steam is cooled in the cooling tower and condensed back into the water.
-The cooled water is pumped back to earth to start the process again.
Not all geothermal energy comes from power plants. Geothermal heat pumps can do everything from heating and cooling homes to heating swimming pools. These systems transfer heat by pumping water or a refrigerant-a special type of liquid, through pipes just below the earth's surface, where the temperature is constantly between 50 and 60 degrees Fahrenheit.
