Use of Geothermal Energy

Some uses of geothermal energy use the temperature of the Earth near the Earth's surface, while others require several miles on Earth. There are three main types of geothermal energy systems.

For direct use and district heating system, use hot water from the hot spring near the ground or reservoir. The culture of ancient Rome, China, and indigenous people used hot springs for bathing, cooking and heating. Today, many hot springs are still used for bathing, and many people believe that mineral-rich hot water has natural healing power.

Geothermal energy is also used to heat buildings through district heating systems. The hot water near the surface of the earth is directly piped to the building for heating. Regional heating system supplies heat to most buildings in Reykjavik, Iceland

Industrial applications of geothermal energy include food dehydration, gold mining, low temperature sterilization of milk, and so on. Dehydration or drying of vegetable and fruit products is the most common industrial application of geothermal energy.

The amount of electricity generated by geothermal energy in the United States is leading the world. Water or steam at high temperature (300 ° F to 700 ° F) is required for geothermal power generation. Geothermal power plants are usually built in locations with geothermal reservoirs, one to two miles away from the earth's surface. In 2017, the geothermal power plant in the United States generated about 16 billion kilowatt-hours (kWh), accounting for 0.4% of all utility-scale power generation in the United States. There are geothermal power plants in seven provinces in 2017

The geothermal heat pump uses a constant temperature near the surface of the Earth for building heating and cooling. The geothermal heat pump transmits heat from the ground (or water) to the building during the winter and reverses during the summer.

In 2015, about 72 billion kWh of electricity is generated using geothermal energy in 22 countries including the United States. The Philippines is the second largest geothermal power plant after the United States and supplies approximately 11 billion kWh of electricity equivalent to approximately 14% of the total electricity generation in the Philippines. Kenya is the seventh largest electricity producer of geothermal energy and electricity, which uses about 5 billion kWh of electricity but occupies the largest share of total thermal power generation, accounting for about 47%.

We will use this using a heat pump. These heat pumps use geothermal energy to heat the air during the winter and then cool the air during the summer. On a large scale, we use geothermal energy to generate electricity. Geothermal energy is a source of renewable energy because it is an energy source from natural resources that can be supplied. Other examples of renewable energy include wind and water. Let's summarize. Thermal energy is the energy of an object or system by the movement of particles in the object or system. Energy is merely the ability to do work and force is done when moving objects. In this case, the system is a collection of objects within boundaries, such as basins. Heat energy is an example of kinetic energy because movement is a particle and movement is key.

Geothermal energy is the heat inside the earth. The word geothermal comes from Greek earth (earth) and heat (heat). Geothermal energy is renewable energy because heat is constantly generated in the earth. People bathe using geothermal heat, heat buildings, and generate electricity. Scientists have discovered that the inner core of the earth is about 10,800 degrees Fahrenheit as hot as the surface of the sun. The temperature range of the mantle is about 392 ° F above the upper crust to about 7,230 ° F of the core boundary.

Geothermal energy below the surface of the earth or heat can be used for electricity or heat. Geothermal heat pumps that heat and cool buildings are effective in all fields. However, geothermal power plants need more active geothermal resources, mainly in the United States.

Geothermal energy is the heat generated and stored on the earth. Thermal energy is the energy that determines the temperature of a substance. The geothermal energy of the Earth's crust arises from the primitive formation of the planet and the radioactive collapse of the material (now uncertain, but probably nearly equal). Geothermal gradients, temperature differences between the center of the planet and its surface promote continuous conduction of thermal energy in the form of heat from the center to the ground. The geothermal of the adjective comes from the Greek root γη (ge) meaning earth and θερμος (thermos) meaning heat.
