Life on earth is fueled by the light and heat from the sun. The total amount of solar energy that strikes the earth is about 3850 zettajoules (ZJ) per year. 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.

You will recover the cost of a solar power system faster than you will recover the expense of conventional power. 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: The movable mirrors are known as heliostats. They are intended to follow the sun in the sky, and can produce temperatures as high as 4000 degrees Celsius. This degree temperature is used for a solar furnace in industries and research. These solar furnaces don’t contaminate our environment.

The heliostats can focus the energy to a boiler that turns water into steam. To generate solar electricity for home use, focusing collectors can be used.

Flat plate collectors: These solar panel products 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.

Sea water is put on the roofs of homes on a tank or ditch and the sun heats and evaporates it and the water vapor turns into liquid distilled water. Solar electricity: The use of focusing collectors and photovoltaic cells, made with thin pieces of semiconductors can make radiation form the sun into electricity. Since it doesn’t cost anything and doesn’t harm the environment, solar energy is not impacted by the supply and demand for fuel. It is unprocessed and unadulterated. It would engender in us a generally higher level of fitness. Together, there are a multitude methods we may implement to achieve optimal output of natural and renewable resources.

Solar power is very beneficial, and can also inspire others to use it as well. The cost of solar energy is less than using gas, electricity, or other types of resources for heat. Even with the low up front cost of gas and electricity, you will end up paying more in the long run. 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 power was available yesterday, it’s available today and hopefully it will be available for us in the future.
