Renewable energy

(1) Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, including carbon neutral sources like sunlight, wind, rain, tides, waves, and geothermal heat.

(2) Today I would like to talk about geothermal renewable energy.
Geothermal energy is the thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials

(3) Geothermal energy comes from the earth itself. Heat from the Earth's core, which averages 3,600 degrees Celsius, radiates towards the planet's surface.

Heating of springs and geysers underground at a depth of several kilometers can be carried out using special wells through which hot water (or steam from it) flows to the surface, where it can be used directly as heat or indirectly to generate electricity by turning on rotating turbines.

Since the water below the earth's surface is constantly replenishing, and the Earth's core will continue to generate heat relative to human life indefinitely, geothermal energy is ultimately clean and renewable.

(4) Direct use of geothermal heat

Geothermal springs also heat them. Hot water is used for heating buildings, growing plants in greenhouses, drying fish and crops, improving oil production, helping industrial processes as milk pasteurizers and heating water in fish farms.

(5) Disadvantages of getting geothermal energy

At the utility level, geothermal power plants are expensive to build and operate. Finding a suitable location requires expensive well surveys with no guarantee of reaching a productive underground hot spot. Nevertheless, this energy has a place to exist.

(6) Benefits of geothermal energy

The great advantage of geothermal energy is its inexhaustibility, as well as its resistance to environmental conditions and seasons. If there are sources of underground thermal waters in the region, it is very advisable to use them for hot water supply.

Along with various types of energy production, geothermal has a number of advantages. Everyone knows that now, to obtain energy, it is important to use resources that are replenished in a natural way. Unlike modern heat sources, no fuel is required to generate geothermal energy. The issue of preventing global changes in the climatic conditions of the planet and protecting the environment can also be resolved with the development of geothermal energy.
