Geothermal energy is 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 (20%) and from radioactive decay of minerals (80%). Geothermal power requires no fuel (except for pumps), and is therefore immune to fuel cost fluctuations.
Geothermal power is considered to be renewable because any projected heat extraction is small compared to the Earth's heat content. The Earth has an internal heat content of 1031 joules (3·1015 TW·hr). About 20% of this is residual heat from planetary accretion, and the remainder is attributed to higher radioactive decay rates that existed in the past.Natural heat flows are not in equilibrium, and the planet is slowly cooling down on geologic timescales. Human extraction taps a minute fraction of the natural outflow, often without accelerating it.
The project of Geothermal energy system
Geothermal energy is now very widespread energy source in the world. However, it isn't popular in Armenia yet. But this type of energy can be very effective in Armenia. AS-TECH offers project planning and system integration for geothermal energy. Also quality of products and service is guaranteed.
Geothermal power is:
- cost effective
- reliable
- sustainable,
- environmentally friendly.
