Life on earth is fueled by the light and heat from the sun. Approximately, 3850 Zettajoules (ZJ) per year is the total amount of solar energy available to the earth. Though the frequency range is different, the suns energy travels via electromagnetic radiation similar to that of radio waves. Some of this energy is absorbed as it comes thru the atmosphere. Heat and light are the primary forms of solar energy. Solar energy has many advantages over conventional energy. The energy from the sun is free the only expense is from recovering the energy. Recently solar cell technology is on the rise.
The cost of recovering the suns energy is recovered faster than with conventional energy. Recovering units work all by themselves, therefore they do not need to be connected to natural gas or power grids. There is an umlimited supply of solar energy and there are no gases emitted to hurt the earth or its atmosphere. There are several ways to recover solar energy: Focusing collectors: This has a movable mirror, known as heliostats, is pointed to the sun and can provide a temperature around 4000 degrees C. This temperature is used for solar furnaces in industry and research, and they do not contaminate the environment.
The heliostats can focus the energy to a boiler that turns water into steam. To generate solar energy, focusing collectors can be used.
Flat plate collectors: These solar power panels can be used in schools and homes to provide heat using water that is heated in pipes. Since they are smaller,they cannot provide much heat as compared to focusing collectors. Solar distillation: Solar distillation units are similar to flat plate collectors; however, distillation units provide water instead of heat for power generation and home heating.
Water from the ocean is placed in containers of the roof of a house. The sun’s rays heat the water, which begins to evaporate. The vapor condenses on a surface, and is then distilled to produce pure water. Solar electricity: By using focusing collectors and Photovoltaic cells, made of thin pieces of semiconductors, convert radiation from the sun into electricity. Solar energy would not be affected by the supply and demand of fuel for it is free and it doesn’t polute the atmosphere. It is unprocessed and unadulterated. It would engender in us a generally higher level of fitness. If we all pitch in and work as a team, there are several options we could use to help conserve both our natural and renewable resources.
Solar power is very beneficial, and can also inspire others to use it as well. Solar energy is cheaper than heat, electricity and gas. Gas and electricity have relatively low initial costs, but you’ll pay much higher ongoing expenses. With solar power you may have an initial investment to turning your home into solar power but after that you have no reason to pay for it any further, unless you use electric or gas for a back up heating source. solar energy is evergreen source which is sure not to vanish at least until the extinction of human beings on earth
