Geothermal energy, the efficient energy source.
Air-conditioning is becoming the essential element of our daily life because of the changes in the climate. In some countries where the outside temperature is extreme, air-conditioning becomes compulsion. The conventional methods use outside air and the temperature is upgraded or downgraded using special mechanism that is compressor and boilers. Efficiency in this method is not high due to the obvious reason. The temperature difference between outside and inside would affect it greatly.
The revolutionary concept of geothermal energy is being used nowadays to maintain the in-house temperature constant throughout the year. It is extremely efficient and effective technique due to a strange phenomenon that occurs in the nature. The temperature of the earth below the ground level is stable all the time and the huge variation at the surface do not reach there at all. Have you ever been in a cave during different seasons? One thing must have come to your notice. The same cave that appears to be quite cool in the summers, feels extremely cosy during the winters! Why this is so? It is because of the same characteristic of the earth. In geothermal pumps, the energy flows to the house in the form of warmer temperature and during the summers, we transfer it back to the earth.
These systems are lightweight, much small and quiet as compared to the conventional system. There is no special expertise required because the mechanism of circulating the air is the same as the normal system. There is extra initial cost involved for drilling that gets adjusted in the long run in the form of very low maintenance and fuel cost. You can attach a water heating mechanism with the same set-up that heats the water in almost half of the cost. Geothermal pumps are environment friendly and much cheaper than the solar energy.
