Investigation Whether Solar Cells are Effective When We Run out of Gas?
The main purpose of the literature review is to examine and study the conducted research in the field of solar cell effectiveness as well as their ability to substitute gas. The main contributors in the studied field are Frailey, Derrington, Peeler, Liu, Colley and others.
Liu (2011) has stated that solar cells appear as the result of growing two different semiconductor types side by side. The scientist provides a detailed process of their creation making emphasis on the fact that solar energy is the source, which is renewable and abundant. The author follows the idea that the material that is used to construct photocells is a key factor since it can affect the efficiencies and the properties of the resultant solar cell. It has been concluded that the best material for solar cells is silicon. Liu suggests a technique, which may be used to provide better effectiveness of solar cells adding to the possibility of using them when there is a lack of gas.
There is an idea that the use of current technologies enables to extract energy from solar methods (Derrington, Frailey, & Peeler n.d., p. 2). In spite of the fact that solar cells are effective and are widely used to produce energy, the author speaks about their production methods, which generate hazardous waste, and may create some problems related to waste disposal. It has been researched that solar panels lead to the reduction of fossil fuel dependence and could aid in such project elimination as coal mining and oil pipelines, which damage natural resources (p. 4).
The article ‘How many solar cells would I need in order to provide all of the electricity that my house needs?’ (2012) provides a critical point of view concerning the use of solar panels as a source of energy as it is very expensive. Calculations concerning the amount of power generated by solar panels have been discussed. It has been stated that the expensiveness of solar electricity would lead to the resection of electricity consumption. Colley (2012) also follows the idea that solar energy cannot substitute natural gas. The author highlights future potential of solar power, which may become an affordable and efficient resource. However, nowadays, energy generated from solar panels is not a cost effective and the best option for many countries. The scientist reveals that solar energy is still not effective due to the fact that the sun does not shine all the time causing the need in batteries, mining of rare earth minerals, which constitute that the solar panel is expensive. It has been concluded that humanity should use natural gas to lower energy costs.
Another critical view is expressed in the article ‘Total Surface Area Required to Fuel the World with Solar’ (2009). It has been questioned whether people may use solar panels as the only source of energy as the whole earth’s surface would be required to supply the needed power amount. The author speaks about the possibility of constructing solar farms, which will lead to the issue solution. According to the article, the ideal places for such farm are destroyed forests and farmland in China. It constitutes 2 1/2 times the solar farm area required to power the world in 2030. The main idea of the article supports diversity maximization of clean energy technologies.
