"Make solar energy economical"

Download file to see previous pages Solar energy technology is faced with engineering challenges however there follow ways of making it more efficient in its production, storage, and use. For example, most of solar cells today that is used for commercial purposes are highly made of silicon that converts electricity from sunlight, with less percentage of efficiency due to high manufacturing costs. Due to use of silicon material the cost of electricity production is three times higher which makes the engineering pauses need for cost-effective cells with low manufacturing costs (Simon, 2007). The current standard cells provide thirty-one percent efficiency due to use of silicon materials. Use of new materials for production by multilayer cells can increase the efficiency. There are also other ways of enhancing the efficiency of solar energy which includes the development of nanotechnology. This is the development of engineering structures which are effective compared to the use of molecules and atoms. This makes them effective because one nanometer is equal to a billionth of one meter. Use of other materials like lead and selenium elements in the making of the cells which make a nanocrystal which is more cost effective and more efficient. With the use of standard cells, there is the production of excess heat when a photon releases an electron to carry the electric charge which makes it ineffective and inefficient enough. On the other hand use of nanocrystals made of selenium and lead elements produces extra electrons instead of heat. ...Download file to see next pagesRead More

.... However, the solar water heaters were later replaced by electric heaters, which used fossil fuels. Solar energy is beneficial in that it does not cause pollution since it does not use fuel to power it on or use several resources to make solar panels (Tiwari 200). It is renewable and one of the least dangerous sources of energy, thus, allowing its usage with almost anything. As the world is fighting environmental degradation, solar energy is advocated for, as it does not cause any risky chemicals. It does not generate whichever greenhouse gases, such as glowing fossil fuels, that mostly cause global...

There is a suggested alternative resource that the government of the UAE should consider. This alternative choice is solar energy. This proposal seeks to bring insight of solar energy to the matter at hand. The suggested option will be elaborately discussed in the subsequent sections. Problem The UAE relies entirely on oil in order to generate power. Using oil as a major resource to generate power is insufficient, as oil is a non-renewable energy...

...?Making Solar Energy more Economical The field of energy economics has focused on energy commodities and energy sources and includes regulatory and market structures; motivating factors to firms and consumers to supply, transport, convert and use energy resources and distributional and environmental consequences. It is cognizant that energy cannot be destroyed or created but can be converted to many forms. It also appreciates that energy comes from the physical part of the environment and returns there ultimately. Providing energy is...

Welling, the CEO of TiSUN who is involved in the renewable energieseconomics in the Arabian markets explained this in these words, “The countries of the Arabian Gulf are among the sunniest regions in the world. With nine hours per day, the amount of sunshine is much higher than in any European country. This is one reason why the Middle Eastern countries provide the ideal conditions for the installation of solar thermal systems” (Welling cited in “Press Releases”). TiSUN G.C.C. FZC has been distributing the solar thermal systems in numerous Emirates since December 2011 that include Bahrain, Iraq, Oman, Qatar, and...

Making Solar Energy Economical
...Making Solar Energy Economical Introduction Solar power is usually generated by collecting the light spectrums from sunlight and converting them to energy in the form of electricity using solar panels that have cells in them. Solar energy forms an integral part of the supply of energy to human beings and the earth in general. The contribution of the sun to the energy requirements of the earth is substantial despite the fact that it has not been taken up by most people and forms only a fraction of the energy consumption market. The total...

...itself is renewable. The maintenance costs of solar power are also quite low compared to other forms of energy (Thomas 11). It is also quite easy to install solar panels which are available at relatively low costs. Solar energy can also be used in any setting, be it at home or an industrial setting. Another main pro of solar energy is its reliability. This is an energy source that will never be affected by geographical, economic or political upheavals (13). One of the major disadvantages of solar power is the fact that it is only available in places which have lots of...

It is through the photovoltaic effect that the solar cell is used to concert solar energy directly into electric energy which is used for various domestic and industrial processes (Energy weekly News, 2012). It has been speculated that it is through the solar PV technology that the mitigation of climate change would be...

...the use of solar collector fluid flowing through the absorber or it can be collected via heat pipe principle where little fluid is sealed inside each evacuated tube. The energy transfer occurs in four different steps: 1. Evaporation of the fluid takes place through solar radiation process. 2. The vapor moves upwards where it meets a colder pipe and some liquid flows through it. 3. Condensation of the vapor takes place. 4. The condensed fluid moves to the bottom triggering the start of the process again. ETCs can also be made as “U-pipe” to replace solar thermal panel to enable heat to flow through one single pipe. The concave mirrors are put behind the collectors...
