Solar energy and its uses
Sun is the most important part of solar system and also a source of energy for everyone, may it be human beings, animals or machines. From heating to cooling, from lighting to cooking, these days everywhere sunlight is taken into use. Sun is the renewable source of energy and it is the one of the energies which is available free of cost and will remain so forever. In some places of the world it is available in abundance while at some receives in some part of the year only, still it is very important. More and more people are shifting towards use of solar energy.
Solar energy is used for various purposes since pre-historic period. Earlier it was used to heat water and for cooking food. With advancement in technology and pressure of exhausting of non-renewable sources, forced mankind to think and use of alternate source of energy. And sun which was once alternate source of energy now has become the main source. These days even air conditioning is also done with the help of solar energy. Big solar cells are placed on the roof where solar air conditioners are installed and then the conditioner does its work. There are sometimes when air conditioning problems come, but there are very good companies which can handle that problem easily and even fix it quickly. Even there are furnace problems and some similar problems which are fixed by specialist in no less time and help in getting back the things right in order.
Lennox is a global company which manufactures furnaces and air conditioners. It even installs it at the place where its clients want. Then there are heat pumps that divert heat from one location (the ‘source’) at a lower temperature to another location (the ‘sink’ or ‘heat sink’) at a higher temperature using mechanical work or a high-temperature heat source. Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat pumps for providing building space heating. A heat pump can be used to provide heating or cooling. Even though the heat pump can heat, it still uses the same basic refrigeration cycle to do this. In other words a heat pump can change which coil is the condenser and which the evaporator.
Thus there are so many uses of solar energy and if harnessed properly it can make a lot of changes in the world sources of energy and can help in living a better a life rather than under pressure of exhausting sources of energy.
