Geothermal energy is heat from within the earth that can be used to generate electricity or heat buildings. It originates 4,000 miles below the surface and sometimes reaches the surface through volcanoes, hot springs, and geysers. There are two types of geothermal energy production: direct use of hot water near the surface and geothermal plants that drill deeper wells to access steam or hot water. Injecting water back into the earth's surface prevents depletion of reservoirs and has minimal environmental impacts. Geothermal energy is a renewable, clean source that operates 24/7 and releases less emissions than fossil fuel plants.

Geothermal energy
Geothermal energy is thermal energy generated and stored in the Earth. It originates from the Earth's core where temperatures reach over 9,000 degrees Fahrenheit. Heat conducts from the core to rock, sometimes melting it to form magma. Magma heats rock and water near the surface. Geothermal power plants use this heated water or steam to power turbines that generate electricity. There are three main types of geothermal power plants: dry steam, flash steam, and binary cycle. Geothermal energy has advantages of being renewable, reducing emissions and fossil fuel dependence, while disadvantages include limited viable locations and upfront costs.

Geothermal energy is thermal energy generated and stored in the Earth. It is a renewable source of energy that can be used to generate electricity or provide direct heat. There are three main types of geothermal power plants - dry steam, flash steam, and binary cycle plants. Geothermal reservoirs are found in areas with geysers, hot springs, volcanoes and high underground temperatures. While the initial investment is high, geothermal electricity generation costs can become competitive with other sources once plants are operational. India has potential geothermal reserves across its Himalayan regions and development is underway to establish the country's first geothermal plants.
Geothermal energy
Geothermal energy is primarily used in China, where 20% of the world's geothermal energy is utilized, and Portugal's Azores islands. In the Azores, geothermal energy is used to power 5 power plants and heat pans of food buried in the ground. Setting up a home or large power plant using geothermal energy has initial costs, but operating costs are lower than fossil fuels. Geothermal energy is a renewable and clean source that avoids pollution and depletion concerns of fossil fuels, though high initial drilling costs are a potential drawback for some. Geothermal plants work by pumping underground hot water or steam through turbines to generate electricity.

Geothermal energy
Geothermal energy is a renewable source of electricity generated from heat within the Earth. There are three types of geothermal power plants - dry steam, flash steam, and binary cycle. Dry steam plants use pure steam directly from reservoirs to power turbines, while flash steam plants use both hot water and steam with a pressure changing system. Binary cycle plants do not use steam directly but instead use hot underground water to boil a working fluid with a lower boiling point than water, which is then used to power the turbines. Geothermal energy has advantages of being available continuously, producing little emissions, and utilizing a free fuel source, but also has disadvantages of high initial costs and potential depletion of steam over time.

Ground Penetrating Radar (GPR) has the ability to map subsurface geological structures and detect variations in moisture that could help understand geothermal exploration. However, GPR is limited to shallow depths of less than 50 meters, where most geothermal reservoirs are located. This study uses GPR data from Beijing to create digital models of the subsurface and identify potential geothermal indicators like quartz sinters. The results demonstrate GPR's capability to detect geochemical markers associated with geothermal activity and map prospective geothermal reservoir locations. While GPR has limitations for deep exploration, it shows potential as a new efficient tool for initial geothermal prospecting.

Future of geothermal energy
This document provides an overview and assessment of enhanced geothermal systems (EGS) and their potential impact in the United States. Key findings include:
- EGS could significantly increase the country's geothermal resource base by tapping into hot rock reservoirs without natural water or permeability.
- The estimated recoverable EGS resource in the continental U.S. is between 2,500-13,000 quads, which could supply current electricity demand for centuries.
- International field tests show hydraulic stimulation is effective at enhancing permeability but reservoir performance is unpredictable. More research is needed to address challenges in stimulation design and reservoir management.
- For EGS to be economically feasible, drilling and stimulation costs must be reduced.

Geothermal energy harnesses heat from within the earth to generate electricity and provide direct heating. It involves drilling wells to access hot water or steam underground that is used to power steam turbines for electricity generation or heat exchange for direct uses. Geothermal energy is a renewable resource with minimal environmental impacts compared to fossil fuels as it does not produce air pollution, greenhouse gases, or require land for fuel production. However, suitable geothermal resources are location-dependent and initial installation costs are high.
