Geothermal energy - basics

 GEOTHERMAL ENERGY - BASICS THINGS


¿What is theotermical energy?
It is energetic source unknow in our country. It consist in the use of the temperature which emanates from the underground of the earth, to produce electricity or climatice homes and buildings. 


Geothermal | Renewable very economical
It is the only energy source that doesn't have a set fee, which depends on the operating possibilities of each country. In the Philippines, Nicaragua or El Salvador derive more than 15% of power through this source.

Geothermal high and low temperature
At high temperatures, the ground water over 180 º in vapor form can be used to produce electricity. And at low temperatures, to generate heat for heating or cooling for domestic air conditioning.

Applications and Uses of Geothermal Energy
Initially, he was closely associated with geothermal areas of the planet with high temperature water tables and shallow like Iceland, Japan and the Philippines. Use underground hot water over 100 ° facilitates the use of steam, to create electric generation efficiency due to the low costs involved use this energy.
However, technology permits to obtain the benefits of this energy anywhere in the world. We are facing an energy that is not dependent on seasonal weather cycles, not accurate fósiltes fuel combustion produces no visual impact or noise or discomfort of any kind.

The household Geothermal Energy
The use of geothermal advances every day, in large part due to significant technological advances achieved. In domestic applications suffice to extend under the garden soil (to 60 cm. Deep) a network of pipes, as if it were an underfloor heating system, which circulates a fluid that allows the exchange of temperature. A reversible heat pump and a heat exchanger are the other elements necessary to achieve a temperature between 19 º -55 º. Enough to cover the needs of a house in winter, and summer. An important quality of the use of geothermal energy derived from the temperature constancy in the subsurface and allows not to depend on the seasonal cycles.
