Since the 1950s, when the solar cells were discovered people were more and more concerned about gaining industrial power and energy at cheaper rates, in the meanwhile, from an environmental point of view the use of the power of the sun is the least polluting process than any other processes.
Nowadays, modern technology and devices are able to transform the power of the Sun into life sustaining energy. It is widely known that an hour of sunshine is enough to satisfy the world’s need of energy for an entire year. Thus, several means of collecting Solar power have been developed which determined its transformation into both heat and energy sources.
Solar energy collection becomes progressively a matter of importance in the development of industrial technology. Governments, whose countries are deficient in source and energy of oil, gas or nuclear power, are inclined to invest in solar farms whose energy would be a substitute of the absent energies.
For instance, in June 2008, the Portugal government launched the largest solar farm project, which consists of thousands of photovoltaic cells able to supply 45MW of electricity each year, enough to power 30.000 Portugal homes, thus reducing the dependence on oil and gas of the region in addition to substantial reduction of the yearly energy bill.
The use of solar energy instead of oil energy hassle the spirits in the oil industry as well. From an environmental standpoint, solar energy would definitely reduce air pollution as the sunlight produces no greenhouse gas, but from a practical point of view oil is much more obtainable and exploitable.
On one hand, as a free source, solar energy would be much more cheaper but the converting industry of the solar power into energy source would be enormous. On the other hand, the advantage of oil stands in its use in the car industry since on a practical level, cars cannot be fueled by solar power.
Solar energy starts to become the part of people’s households as well. The ability of solar power of producing high temperature without the use of fuels is more and more employed in generating heating. Consequently, in many homes petroleum generators were replaced by solar generators, which besides water heating, supplies a significant percent of electric energy.
Although, gas, oil and nuclear energy are the leading energy suppliers in the world, in the following decades solar industry will definitely gain field in the energy industry not only as an expense reducing factor but as well as an environmental protection issue.
