Relationship Between Communication and Human Sciences

Relationship Between Communication and Human Sciences The aim of this paper is to critically analyse communication and its development of human societies. It will scrutinise whether any form of symbolic behaviour was a form of communication. This essay will question some of the findings of the past through the examination of communicative works such as cave-art. Discussion of urbanism and religion as a means of communication with divine or supernatural powers will then follow. Writing as posited as one of Childe’s ten criteria as a cause of urbanism will be critically evaluated. To conclude, I will offer my perspective on the development of human societies having evaluated the evidence and expert views. So what is communication? Communication is derived from the Latin word communis (Peters, 1999), meaning â€Å"to share†. Thus, communication is the activity of conveying information through the exchange of messages, information, and thoughts, as by signals, visuals, writing or behaviour. The history of communication dates b ack to ancient times, speech which revolutionized the human communication was developed some 200,000 years ago; symbols were developed about 30,000 years ago while writing about 7,000. Throughout the millennia, human societies underwent major changes in their social order where people lived 10,000 years ago in small, mobile groups which depended on wild plants and animals. Examples of those groups include but is not limited to those of the Yangzi river valley in East Asia and the Americas which underwent changes from hunter-gatherers to an organised society. It is these early examples of groups which domesticated local plant and animal species to forge a farming community and with the development of agriculture and sedentism, population growth soon followed. These farming societies transformed themselves into larger, more complex social systems characterised by cities, political states and class inequalities. As with civilisations such as those of Egyptian and Roman empires, rulers and dynasties rose and fell, and the potsherds and stone tools of archaeology made way for written documents. Without communication, the lives of human beings would be very different as it is critical for growing and maintaining everything around us. The relationship between communication and human society is ever-growing having achieved a huge growth in its partnership. Humans simply could not have achieve this kind of development and growth without the existence of communication. Within society, all relationships and social connections rely on communication and appreciate and understand its importance and with varying communication methods and processes, it gave a great boost to the development of human society. Communication as it is today is a continuing process as people strive to develop new and innovative communication methods and processes. To fully appreciate the growth of communication, we need to look back to the beginning to  the stone age when communication was in its initial developmental stages. There were no languages, resultantly little communication processes were followed by humans. The swift development of human abilities made way for the development of communication and human society. Humans began to use signs and non-verbal communication to communicate with fellow humans such as runners, birds, arrows, smokes. As humans became more and more organized, different kinds of languages and communication methods were developed. Major developments during the Stone Age were: Cave paintings Petro glyphs Pictograms Ideograms Later, during the Bronze Age, human beings invented writing which revolutionized the communication methods and processes, there began a new period of communication. Accepted examples of such writings are Egyptian hieroglyphs and the Indus Valley script (Tharoor 2009). By 2700 BC Egyptian writing had a set of some 22 hieroglyphs to represent syllables (Crabben 2011). Some of the prominent developments of these times are: Writing Alphabet Paper With the introduction of various form of communication, is the question whether symbolic behaviour is a form of communication? Communication and symbolic links seem to go hand in hand with features seen as symbolic objects such as daggers, warriors– some carrying weapons, axes, wheeled vehicles, houses, farm buildings and livestock. Other evidence presented is the rock-art of Valcamonica (Italy) and Southern Africa in which a number of symbolic representations were discovered. Southern-Africa in particular has cave-art of varying degrees of what I would consider a form of symbolism such examples include dancing women an various geometric forms. I believe that symbolic behaviour could be considered as a form of visual communication because a message is being conveyed irrespective of the media and form of communication. Not restricted to cave-art, symbolic behaviour is also seen through the construction of objects such as the sky-disk and sun chariot. The Nebra sky-disk depicts the sun, moon, 32 stars and two arcs, originally three. Its significance alludes any understanding of its significance, however, it does not detract from the fact that it is symbolic in nature and may have been used as an astronomical calculation tool to determine times of harvest (Haughton, 2011). Whatever the significance of the disk, it is still one of symbolism. The final piece of symbolism lies with the Sun Chariot, similar in its astronomical representation of the sun and moon which again illustrates a form of symbolism in the form of a bronze-wheeled-model of a horse pulling a large disk. Not isolated to mere models of bronze, the discovery of burial practices and metallurgy to display prestige and cultural practices can also be considered as a form of symbolism. Unfortunately, no depiction of the latter practices are represented in the rock-art, suggesting that the presence of cave-art does not fully represent the full range of activities, but does not exclude the very fact that once again symbolism is represented through prestige. Symbolism was prominent on a global basis and in Southern Africa, rock-art had symbolic meanings to those who created them. The representation of these paintings were linked between the material and spirit world which in turn depicted shamans and the spirit world. I believe that any consideration into the varying forms of symbolic behaviour should be seen as a form of communication. In summary with regards to symbolism and communication, I am inclined to support the idea that symbolism is a form of communication which is reinforced by Childes criteria for urbanism and the rise of civilisation coupled with the development of symbolic art (Perkins, 2013). Cave or rock-art is known as the oldest form of communication and is the precious remnant of an ancient way of life which provides some of the oldest clues of cultures from long ago. Rock-art and art form or drawing style provides a recorded history of human thought patterns and behaviour. Insights into their socio-religious aspects as well as their ancient culture and myths can be gained and prove valuable into gaining an insight into their lives. Between 30,000 and 5,000 years ago, no written records existed except for cave-art and rock etchings. It was not until post 5,000 years that other types of written records came into existence. Rock-art is in my opinion considered a form of communication and message, whether simple or complex, is special but yet to be fully understood. It provides a small glimpse into the socio-religious aspects of these ancient neolithic cultures. A number of theoretical views and opinions have purported to explain rock-art, but in my view, I am inclined t o suggest that rock-art simply portrays simple daily life. Another possible theory could be that of conveying a complex message about the shamans journey and their altered state of consciousness, suggesting a true appreciation and understanding of ancient tribal life. An air of caution must be placed in assuming that the paintings produced in a specific tribal social and religious context within cave-art has any resemblance to the belief systems of modern Western society and therefore should not be gauged to such. Any form of ritualistic, mythological or supernatural representations art is open to debate as to whether it is art or religion. The area surrounding art and its link to religion would be a difficult assumption to make as to view the work within a set context is to view the art in the same way as those who were around during that time period. As with any religious content, the interpretations are hypothetical and subjective based on the interpreters ideals. However, the presence of animals may have been more of a symbolic vision of the world around them. This art could also be a way of communicating possible ritual practices (Zorich, 2011) that may have taken place within the cave systems. There is a possible assumption that ritual practices taking place within the caves were a means of communication with divine or supernatural powers. The imagery of animals may have been viewed as sacred due to their physical strength indicating power. Throughout time there have been links with sham anism and rock art within the context of spiritualism. One such example is that of the Valcamonica figure which depicts a running man (Naquane, 2014), often identified as a shaman. The key controversy is that the art is a representation of the real world and with that consideration it questions its true purpose and functions. As with everything else in life, changes occur, additions are made to existing structures and art work; likewise with cave art by engraving over already existing work in addition to leaving existing engravings alone, signifies a meaning for those adding to the already present art. It is fair to surmise that maybe these images may have had a symbolic or religious function which in turn can be accepted as a form of communicating rituals and the idea of theology. To further support the theory, Scandinavian rock art is suggestive of ritual or mythological as well as associations with the supernatural. I truly believe that such interpretations are acceptable and sho uld be viewed as a way of looking beyond an established civilisation to that of conducting oneself to a higher power, a deity perhaps? Further evidence has recently come to light of the possible religious or spiritual practices from the discovery of rock-art in the highlands (McKenzie, 2014). The discovery included a boulder decorated with ancient cup and ring marks which archaeologists believe may have been made for a number of reasons. Some of these reasons include ritualistic, astronomical or simply doodling. If we were to assume that it was ritualistic, it implies that there may have been a link with divine or supernatural powers. It is a safe assumption that with cave-art, a link between communication and the belief of divine and supernatural powers exists. It is without a doubt that human communication is underpinned by a social survival imperative. In the words of Blakemore, Winston and Frith (2004) Humans crave the company of others and suffer profoundly if temporarily isolated from society. The above statement is indicative of the need to communicate hence with the spread of hunter-gatherers across various regions, communication took on differing forms. These ranged from non-verbal communication which consisted of possible facial expressions, tone of voice, body movement and stance which eventually emerged in conjunction with verbal communication within the hunter-gathers period. It is through the use of language as a symbolic form of communication to convey messages to one another but is not limited to just the verbal aspect of communicating. As previously mentioned, writing, drawing, painting and sculptures was and still is a form of communication, a graphical and yet symbolic method of communication. One asserts that the hunter-gathers of the time used various methods to communicate from non-verbal to verbal as well as art to project and record their beliefs and lifestyles. The earliest form of urbanism appeared in the Near East (3rd Millennium BC), Warka, known from texts as the Sumerian city of Uruk (Mathews, 2013). Life in the City of Warka was marked by the appearance of well known cultural innovations such as the architecture of monumental portions, commemorative art and the use of a cylinder seal. Another innovation which involves one of Childes ten criteria is that of writing which appeared during the late Uruk period and was considered the earliest form of writing. It can be implied that the presence of writing was not coincidental but one of relevance towards the formation of social organisation. I believe that writing is essential in maintaining any form of governance within a state organisation. My argument is that writing as it stands provides a method of record keeping which is essential for not only the organisation but also the administrative and social control of people living within an urban setting. If proven that the writing found at Uruk was indeed an integral part in urban life then it will be a safe assumption that the presence of writing was in effect consistent with governmental administration. However, I dispute this perspective since other societies have existed without the need for writing to maintain a society. One such society was that of the Incas. Not having a recognised writing system like the rest of the world, no carved stone, no papyrus or art, the Incas established and maintained a working empire proving that urbanism does not require a writing system to flourish. Having said that, the Incas did have a method of recording accounts, astronomical calculations and possibly their stories, this method involved the use of cords and knots (K.K. Hurst, 2002), a complicated system but yet a record, nevertheless. Having considered the Incas and the use of the cord system as a possible means of conveying messages is in my opinion open to debate as to whether the use of knots in cords is a form of communica tion. Critical analysis of the communication adopted by the Incas does not provide a convincing argument therefore in my opinion that it is highly improbable the Incas possessed a system of writing. When taking into account that for urbanism to exist and thrive, a system of communication is required, be it writing or otherwise, the Inca civilisation as far as I am concerned refutes that theory. Would the Incas have adopted writing from the people of Warka? Due to the strong beliefs of the Incas and the significance of the cord system, I would assume the Incas would have refrained from doing so. In concluding this paper, the true significance of these vast array of cave paintings discovered and possibly some yet to be discovered is and will remain elusive for now. I can conclude that the cave-art, some brilliant in comparison to the art work that we find today, reflects the development of symbolic life, and an important turning point in human evolution. This sudden burst is reminiscent of the big bang theory but in this case it is the big bang theory of the human mind. It is through the study of the cave-art that has drawn a possible link to a symbolic life and with further field study and analysis will push the theory and reveal a symbolic life from the past. I also believe that communication and its impact on past civilisations may not have had a major role to play just simply a system which was adopted for growth and control. Today, communication is a requirement for any country to succeed and flourish in the way of trade and finance as well as the setting down of laws. A s we have come to know, the effect of communication is one of globalization, take communication away now and we are left with ignorance and loss of what we have to know as part of everyday life.

Lewis Thomas Essay

Biologist Lewis Thomas argues that mistakes should be thought of as a blessing rather than a misfortune, because they pave the way for new discoveries and understandings. As can be seen with past events and happenings, this claim proves to be valid as mistakes are necessary for progress. Various scientific advancements throughout history have been errors turned into findings. Such an example can be seen in medical discoveries. Penicillin, founded in 1928 by accident, was at first thought to be useless, but after countless experimentation it was finally used as medicine and a Nobel Prize was received for it. Other substances that were discovered by coincidence include Viagra and a small pox vaccine. Viagra was originally a cardiovascular drug but during the testing phase it wasn’t effective in treating heart ailments. Scientist continued to study the unexpected side effects which were an effective treatment for erectile dysfunction. Small pox vaccination was encountered through the injection of cow pox into an eight year old boy which resulted in a counteraction of small pox. These are merely a few of that many scientific findings that at first were thought to be mistakes. The nutrition industry of The United States of America would be incomplete without the numerous, spontaneous, discoveries over time. A man in San Francisco accidently left his juice outside in the winter and it froze. He ate the frozen juice and came up with popsicles. America’s favorite chocolate chip cookies were also a mistake. When the Toll House Inn’s Ruth Wakefield ran out of baking chocolate one day in 1930, she smashed up a bar of semi-sweet chocolate and added the pieces to her dough. Upon their removal from the oven, the cookies weren’t uniformly infused with melted chocolate, but rather studded with little chunks throughout. The signature sweet put her Whitman, Massachusetts inn on the culinary map. These accidental discoveries are what made the food industry what it is today. To be successful you have to be willing to do whatever it takes to gain that success. Even though people seem to believe that when you’re trying to be  successful mistakes should be avoided. However, that is not the case because through mistakes you are able to realize what you did wrong and correct it to what you’re supposed to do to be successful.

Why Should I Be Moral? The question of morality proves to be a complex interrogatory. Should I be moral? If I should be, then why? Why is morality important to society? An assumption can be made that morals derive from a purely religious perspective or the Golden Rule approach. We are told that it is right to be moral.

In the following passage, there is a case study to discuss which kind of health assessment can be used in order to provide a better nursing care for a patient. Case scenario Mr Wong, aged 58, arrived at my ward with his wife. He was sweating and coughing. He had a difficulty of breathing and a wheezing sound was heard. After 15 minutes of rest, he felt better. He explained that while he was chasing a bus with his wife, he felt breathlessness and dizzy. He did not recovered after resting for awhile on the street so his wife brought him to the hospital. Mr Wong was a retiree for a year and he was a constructive worker before. He explained that retirement was because of not enough energy for daily work. He had smoked for over 30 years, one and half pack of cigarette per day, and had 5 cans of beer every week. He was obese and had medical history of hypertension for 5 years with own medicine. He was married and lived with his wife in an old building. He was fatigued when climbing up the stairs as well as walking for awhile. Due to the fatigue, he reduced the social activities and stayed most of his time at home. He complaint of not having a good sleep because of night cough (on-and-off for a year) and kept coughing with production of sputum for a year. Besides, he had respiratory track infection more frequently in this year. In recent 2 months, he had poor appetite and lost 8 pounds. During the conversation, Mr Wong usually needed a rest for answering every 3 questions. He looked tired and had deep circles under his eyes. His lip was dry. He was upset about the fatigue and felt useless of himself. He said that his quality of life was affected and lost interest of his previous hobbies. He did not have any social activities in this year nearly. Mr Wong had a low grade fever and blood pressure was around 145/90. His pulse was around 110. He had taken a chest X-ray after admission and the result was pending. He took the test of spirometry and FEV1 was between 40-50%. His 12-lead ECG was normal. 2-liters of oxygen was given through nasal cannula. He always sat up and seldom leaving the bed. Mr Wong was diagnosed with chronic obstructive pulmonary disease (COPD). When Mr Wong arrived, I took vital signs of him as a baseline. His weight as well as height were recorded. Then I took the health history by an interview. The interview was started with the main complaint of Mr Wong. After that I took the past health status. They were medical history, done surgery, medication history, food and drug allergy. The lifestyle and health practice of Mr Wong were also asked. It included different areas. Smoking and drinking must be included as both were the risk factors of COPD. From his diet, hobbies and activity level, I needed those information for discovering the reasons of weight loss and obesity of Mr Wong. I also asked Mr Wong if he had constipation while if he felt breathless during passing stool and bathing. After the interview, I held a physical examination for Mr Wong. There were 2 parts, inspection and auscultation. I measured the respiratory rate and rhythm and observed the shape of his chest and any central or peripheral cyanosis. Auscultation was followed. I recorded the abnormal sounds like wheezing. Advanced nursing health assessment In the case of Mr Wong, a very simple and brief health assessment was done. It was unsatisfied because the health assessment was not completed and informative. The following passage is going to provide more health assessment and methods which can improve the case of Mr Wong. Health history The interview of Mr Wong was too brief. More questions should be asked. First of all, Mr Wong’s family history should be reviewed as COPD can be inherited (CMP Medica, 2007). More information of his blood relatives such as patients, grandparents and children has to be obtained. Nurse can find out any rare illness among the families which may relate to respiratory disease (Barnett, 2006). Secondly, Mr Wong work history should be also assessed. Since he was a constructive worker, he usually exposed to the chemical irritant. The nature and the environment of his work directly regard to COPD. Nurse needs to identify any personal protective equipment he used as well (Weilitz Potter, 2007, p.157). Thirdly, information regarding home conditions is important to establish how Mr Wong coped at home. As he was living in an old building, the building may be without a lift or with many stairs. It is possible for Mr Wong having difficulty to go out or it may be the reason of reducing social activities (Barnett, 2006). Fourthly, nurse has to question Mr Wong’s sleeping pattern as he did not sleep well because of night cough. Nurse should document how many hours he slept and why he could not sleep well. Sleeplessness or limited sleep may lead to tiredness and inability to cope with daily activities. By knowing the cause, doctor and nurse can treat the night cough of Mr Wong to deal with the insomnia. And they can prevent giving treatment with night sedative due to the side effects, which may depress the respiratorycentre(Barnett, 2006). Physical examination The physical examination includes different parts which can give a complete picture of Mr Wong’s condition. They will be introduced one by one, from simple to complicated. Body mass index From the article of Shepherd (2010), it states that â€Å"Nutritional depletion in patients with COPD is common and has negative impact on respiratory and peripheral muscle function. You read "The importance of health assessment in understanding patients" in category "Essay examples"†(p.559). As Mr Wong had poor appetite and lost 8 pound in 2 months, the body mass index (BMI) should be recorded for follow-up. Nurse has to find out causes of weight loss and deals with those problems efficiently. COPD assessment test COPD assessment test is a simple questionnaire. It is used to measure the impact of COPD on the life of patient, and how this changes overtime. By this test, nurse takes it as a reference to improve the treatment. The test contains 8 questions. They are the frequency of coughing, if he feels any mucus in his chest, if his chest feels tight, if he feels breathless when climbing up hills or stairs, if he is limited doing any activities at home, if he is confident leaving his home despite his lung problem, if he sleeps soundly, if he has lots energy(GlaxoSmithKline, 2009). Medical Research Council( MRC) Dyspnoea Scale Measurement of breathlessness is essential for a COPD patient. The Dyspnoea Scale of MRC allows patients to grade their breathlessness on a scale of 1-5 according to activity carried out. The degree of breathlessness related to activities is from grade1-5 which means from mild to severe. It acts as a baseline and is useful for monitoring purposes for nurses and doctors (Barnett, 2009). Physical examination of Chest Through the process mentioned in above passages, nurse can receive higher proportion of basic information about Mr Wong’ condition. In the coming passages, several techniques which focus on chest are going to introduce. There are 4 physical respiratory examination, inspection, palpation, percussion and auscultation. Although inspection and auscultation were applied in the case of Mr Wong, they were imperfect. Inspection Inspection consists of several parts. For the case of Mr Wong, nurse mainly focus on the inspection of breathing pattern, use of accessory muscles and positioning (Weber Kelley, 2010). Nurse needs to observe the rate, depth and rhythm of respiration. If these factors are abnormal, they represent the increasing workload of breathing. The pattern of respiration should be recorded if there is any special such as tachypnoea, hyperventilation, Cheyne-Strokes respiration, Biot’s respiration†¦etc. It allows the doctor giving particular treatment (Massey Meredith, 2010). Abnormal posture shows the patient may have difficulty in breathing. Mr Wong always sat up or leaned forward because he can better tense the respiratory muscle and contractility (Massey Meredith, 2010). In addition, using of respiratory muscles (trapezius, or shoulder) helps inspiration especially chronic airway obstruction (Weber Kelley, 2010). Nurse should pay more attention and provide suitable nursing care (such as oxygen supply, suction, removing tight clothes†¦etc) when above symptoms occur. Palpation Palpation for tenderness and sensation can determine whether there is inflammation, muscle sore or infection. It can be performed by one or both hands following the sequences. It should be started towards the midline at the level of the left scapula then the nurse moves her hand from left to right. The moving is systematically downward and out to cover the lateral portions of the lungs at the bases. The nurse should compare the finding bilaterally. The nurse can also check if there is mass or tumor (Weber Kelley, 2010). During the palpation, a crackle sensation may be sensed which means crepitus. This sensation is because of air passing through fluid and exudates in the lungs. Fremitus should be assessed. It is a vibration of air movement through the chest wall. It can be increased, decreased or absent which represent different lung problem like consolidation or bronchial obstruction, pulmonary edema, pneumothorax†¦etc (Weber Kelley, 2010). Percussion Percussion has 2 main functions, determining the tone as well as the diaphragmatic excursion. When nurse percusses the chest wall, the sound produced can show whether lung tissue is filled with air, liquid or solid. Same as palpation, a sequence of percussion should be followed. The process is started at the apices of the scapulae then across the top of both shoulders. Next, nurse percusses the intercostals spaces across and down. Finally, she moves from the lateral aspects at the bases of the lung (Weber Kelley, 2010). By comparing the sound of percussed areas, nurse may discover the lung mass or other respiratory problems (Weilitz Potter, 2007). Measuring the diaphragmatic excursion is also important. Emphysema may be a cause of limited diaphragmatic descent. Auscultation For auscultation, breathing sound is not the only element to assess. The voice sound can also be assessed. It is easy that nurse auscultates the chest wall while she asks the patient to repeat pronouncing â€Å"ninety-nine†. This is the way to identify if there is consolidation from pneumonia, atelectasis, or tumor (Weber Kelley, 2010). Mental state For the patient with CODP, they usually reduce the daily activities like Mr Wong did. The patient may not use to the changes of the quality of life( ,2010). Closely observation and listening to the patient are the easiest and useful ways to assess the mental state of the patient. If there is any abnormal, the condition should be recorded and report to the senior nurse. Conclusion In this article, some health assessment tools and techniques are suggested for a CODP patient, Mr Wong. There is no traumatic procedure involved. However, the results of different examination can give large amount of information of the patient’s body condition. And this is essential for the clinical staff to improve the clinical decision making in order to provide better treatments for the patient. Reference Barnett, M. (2009).

Renewable Sources of Energy

Question: Discuss about the Renewable Sources of Energy. Answer: Introduction: Renewable sources like sun, rain, wind, waves, tides and geothermal heat that are naturally replenished and provides energy for water and air cooling, electricity generation, transportation and energy services (Twidell Weir, 2015). They are generated through natural processes capable of replenishing itself. This type of energy is constantly renewed and is inexhaustible. The biomass including solid waste, wood, biogas and biodiesel are also the renewable forms of energy (Lee, Speight Loyalka, 2014). The use of renewable sources of energy has both benefits and disadvantages. There are several benefits of using renewable sources of energy. The sources of the renewable energy could be easily replaced. The renewable sources like sun, wind, water, land and geothermal heat do not pollute the environment. As a result, it does not contribute to the green house gas effect. The sources are carbon neutral that does not produce carbon compounds. The biomass, land, air and water are naturally available and are not formed. The great benefit of using renewable energy sources is that they can be trapped and are non-exhaustible. These sources are safe for the environment and are not so expensive compared to non-renewable sources of energy. The solar energy is obtained from the sun directly or indirectly and is used for lightning houses, buildings and heating hot water and in a variety of commercial and industrial purposes (Ellabban, Abu-Rub Blaabjerg, 2014). The hydroelectric power is generated through wind energy heated by sun turning into vapors. These vapors turn into rains flowing through rivers and streams generating hydroelectric power. The plants grow with the help of sunlight and that makes up the biomass consisting of organic matter used for producing electricity, chemicals and transportation fuels. The earths internal energy is trapped to generate electricity, cooling and heating of buildings (Dickson Fanelli, 2013). The hydrogen is found in many organic compounds being the most abundant element acting as an energy carrier. The technologies produced using renewable sources are the cheapest form of energy production. It provides benefits on a large scale in terms of market production and mass production. The levelised cost of energy is declining for the renewable energy sources and the cost is also less for the energy production. The renewable sources are the most economical solution for energy production with good capacity. Th e energy produced by using renewable sources does not emit greenhouse gases contributing to the global warming. Renewable sources of energy reduce the dependency on the fuels and energy obtained from the foreign governments. They are sources of constant energy and provide a vast supply of energy. They are clean sources of energy and are considered safe for the environment. They have no carbon emissions and as a result, do not contribute to the global warming. The sources are sustainable and will not run out. The renewable sources do not deplete the natural sources and have minimal impacts on the environment. It enables to reduce pollution and keep people healthy. They are the reliable sources of energy as the wind; sun and water are available on a large scale over geographical areas. The use of renewable energy sources require less cost maintenance and reduce the costs. It also stabilizes the energy prices as the invested money would be less and there is no need of heavy pricing (Bahadori, Zendehboudi Zahedi, 2013). Along with the benefits, there are disadvantages of using renewable sources of energy. The biggest disadvantage of using renewable energy sources is that it is entirely dependent on the weather. The sun, wind or rain is the sources of natural climatic conditions and due to unprecedented patterns of weather; the energy use is minimized in those cases. If the weather fails to produce these climatic conditions, then the sources of renewable energy would not be able to make energy (Tyagi Lo, 2013). The energy production by renewable sources cannot be generated in large quantity when compared to energy production by non-renewable sources. This problem could be mitigated either by furnishing the increasing demands or by reducing energy consumption. The construction and building costs of the plants for the renewable energy production are initially high. Moreover, the plants require upfront investments, high maintenance costs, careful planning and attentive implementation. The high energy g eneration is not possible by using renewable energy sources and is highly inconsistent and unpredictable (Scheer, 2013). As they are dependent on climatic conditions, unavailability of the sources would lead to failure of energy production. To set up plants for the energy production through renewable sources, large land tracts are required. There is requirement of large wind farms and solar panels to produce enormous energy and for that large patches of land are required when compared to energy production by non-renewable sources. The construction wind farms also spoil the country side. The implementation of the big solar panels is costly. In the case of tidal energy generation, the barrage construction is very expensive. Moreover, the construction would cause the destruction of wildlife and requirement of suitable estuaries (Sanchez et al., 2014). There is flow of sewage into the sea and reduction of tidal flow due to the implementation of tidal barrage. The energy generation through wave power is also expensive and may be opposed by environmental groups as the seawater is moved in and outside the cavity on a shore trapping air to drive a turbine. The geothermal energy generation is also costly and most importantly it could only be set up in areas of volcanic eruptions. Therefore, the volcanic and geothermal activities might settle down but the power stations would become redundant. This would increase the cost of renovating and maintaining the large geothermal power plants after being destroyed by volcanic eruptions. As a result, the dangerous and toxic elements that are found underground would be exposed to the surface (Bagher, Vahid Mohsen, 2014). The cost is high for the implementation of hydroelectric power plants and could lead to flooding of the nearby surrounding areas. The local hydrology is immensely affected by the construction of dams and posing ecological damage. The energy production through the burning of biomass emits carbon that contributes to the greenhouse effect. The biomass energy production is useful only when there is replanting of crops. The wood is also considered as a cheap method to generate light a nd heat. However, burning of wood pollutes the environment giving off atmospheric pollutants that include the greenhouse gases (Vassilev, Vassileva Vassilev, 2015). This process also requires replanting of trees otherwise wood would become a non-renewable source of energy. Therefore, the use of renewable sources of energy has both benefits and disadvantages.
