The light and heat generated by sun can be conserved for diverse energy and power applications. Solar energy source of energy is under the phase of development and experimentation. Solar energy valuable energy is capable of providing heating, ventilation and fuel alternatives. Sun is an abundant energy resource and most of all it comes with the environment friendly package. Hence it is a common thought now that this energy source would lead towards its way to the end of this century.
Chemical Reaction in the Sun
The sun is the ruling star in of our solar system. This useful star provides us comfort, energy and growth. It is the presence of sunlight that we are able to grow plants and cultivate our barren land. Hydrogen consumed during nuclear fusion present in the sun generates radiant energy. This process helps the solar rays to reach earth in the form of very small energy packets called photons. These photons are absorbed by our oceans and land. When the sun rays reach to earth they interact with the oceans and rivers. The heats present in the sunlight facilitate the process of evaporation. It is in this process that water vapors, winds and cyclones are produced. If we implant aerodynamic wind mills in the way we can generate electricity from this process as well.
Solar Energy Working
If we store sunlight for constant 20 days we can replace a yearly reserve of coal, natural gas and oil. The energy present in the earth’s outer atmosphere is about 1300 Watts, which reduces to 1000 Watts when it finally reaches the earth. The solar energy works only if we store it. Solar energy collectors are now implanted to store this energy. These are large flat black containers which are covered by glass. These solar energy collectors are placed ate the roof tops or in large barren land which is specifically allocated to solar energy consumption. The collector contains pipes which carry liquid in them. The liquid is a mixture of alcohol and water. This process either heats the water or air (the air is carried through the radiators to the building).the working of solar energy is also dependent upon how we utilize and transform it.
Conversion of Solar energy
The solar energy is converted to chemical energy when plants use it to perform the process of photosynthesis. Hence solar energy works by utilizing its light and heat effectiveness. The solar energy is converted into thermal solar energy by directly converting the heat from the sun into thermal energy. When the power of the sun rays is converted into the electricity with the help of chemical reaction in the solar cells, it is an example of Photo-voltaic conversion of energy. It is important to understand here that solar energy works naturally to facilitate the growth of plant and the working of our echo system. However now there are many artificial ways to make use of the solar energy. This solar energy works for us humans if we store it using different storage devices like the panels, solar cells and scheffler reflectors. Simple examples of solar cooker will explain how this solar energy works? Solar cooker is comprised of metal foil. This metal foil is capable of storing heat. When we place this solar cooker under sun for an entire day .it stores enough heat in it for the purpose of cooking food later in the evening. These solar cookers were invented to prevent immense deforestation in the rural areas. These cookers are an inexpensive and environment friendly way to cook food. The reason for environment friendliness is that these cookers do not generate harmful gases like carbon monoxide.
