Hydroelectric in Philippines Essay Example for Free

Hydroelectric in Philippines Essay It is known to us that energy become more and more important to human beings. People can not live without energy. They use energy everywhere, but pew of them can give a clear definition of it. Because of people’s widely use, the energy on the earth reduces steadily, people are trying o find the energy which can be renewable. Energy is the thing which has the ability to work. It can be stored or be a poverty of an objects motion. It can move from one object to another, and defines the capacity of system to do work. Obviously, renewable energy is the energy which can be used over and over again, from natural sources. There are so many renewable energy people use nowadays. For example, they use solar energy, the wind and the hydro power. From year 1981 to 1991, renewable energy developed very fast, and the following text may concentrate on the hydro power. Hydro power is the energy driven by water turbine, People always use it to produce electricity. The falling water drives the turbines, and the turbines in turns to drive the generators. Then the generators translate the turbines’ mechanical energy into electricity. The hydrologic cycle produces neither atmospheric nor the normal pollution. Hydro power has been used since ancient time, and is can be used for grinding floor and performing other tasks. In 1878, the world’s first hydroelectric station was developed in NORTHUNLAND, and by 20th century, it become the largest part of renewable energy all over the world. Everything has two faces. Though the hydroelectric has a lot of advantages, for its low cost and low pollution, still it has some disadvantages. In some Asian countries, like Philippines and China, people can see the hydroelectric production clearly by year. There are some hydroelectric stations which are typical in these countries. Like the Bela in Philippines and the Three Gorges Dam in China. What’s more, we can also know something about the development of hydroelectric in these countries. The following text will give more details about the hydroelectric production, the hydroelectric stations and the future development of hydroelectric in Philippines and China. Body: â…  .Hydropower production by year Since the first Edison hydroelectric power plant begin to use in 1882, September 30th, (industry archive logy review, 1987), hydroelectric become fast developing. During 1981 to 1991, it developed very fast. It can be seen clearly that hydroelectric become more and more important in human’s daily life, and also they can see the trend of development of hydroelectric in Philippines and China. In Philippines, people can get the information directly from the line chart that there was a fluctuation in it. It produced about 3.8 billion KWH in 1980, and had a tiny increase reached at 4 billion. Then it fell back to 2 billion KWH in 1983 and raised again. It has risen steadily from year 1983 to year 1986, from 2 billion KWH to 6billion KWH. Things looked the same from then on, but the trend is increasing. By the year 2003, the production of hydroelectric power was more than 10 billion KWH. After that, it remained steadily, by the year 2010, the production of hydroelectric was 9.8 billion KWH. Hydroelectric in Philippines takes 19% of all electricity consumption and the rate constant for decades. (Bronuyn-W, 1998) However, in China, the hydroelectric production grows steadily. It has risen from 80 billion KWH in 1980 to more than 300 billion KWH in 2003. People can predict from the line chart that it will be a more and more part of energy in Chinese electric production. It takes about 49% of all the renewable energy in China. (World Institute, 2010) Hydroelectric is very important, not only in these two countries, but also all over the world. In Democracy Republic of Congo, Paraguay and Brazil, hydroelectric takes 85% of their electric. In the USA, more than 50% of electric comes from it. That means hydroelectric really plays an important role in people’s life. â… ¡.Examples of the hydro electric station For the reason that hydroelectric really take a great part in electric production, there are some hydroelectric plants which are typical in Philippines and China. In Philippines, the AGUS-â… ¡ station may be the earliest one. It located on Lanow del Sur. The operator of it is National Power Corp. It can produce 3*60 MW Francis and still it can be used though it was been built in 1979. The BELEA, which is the biggest one in Philippines is located on Negros Occidental. It has been built in 2008, and can produce 1*39 KW crossflow. The operator of the BELEA is WINROCK international-preview Negrs. In China, the Three Gorges Dam should not be missing. It began to built when in December 1994, and was finish in May 2006. It is expected to produce 18.2 billion pound watts, and it is the biggest hydroelectric station in China. In 2008, October, all the equipment in the Three Gorges Dam were put into use. Evidently, it dose solve the electric-short in eastern China. Another hydroelectric station in China which usually be ignored is call XIN’AN River Station. It was built in 1957 and finished in 1960. It is the first station China designed and built itself. It has been working for more than 50 years and it can produce 1.96 billion KWH per year. â… ¢ .The influence to Environment and People Everything has two sides, no exception for the hydroelectric station. As stated in the previous paragraph, the hydroelectric station has some bad effects. Generally, the disadvantages can be listed as follows. For the reason there are so many hydroelectric station on Changjiang river, there will take it for example. The most direct impact of cascade reservoirs is that continuity of river is break. Though it may make people have more place for cultivation, it may caused some endangered species died out. It will damage the habitat of the fish even the HUCHO BLEEKERI, a kind of rare fish has already died out. The disappearing of the species may affect the structure and balance of entire ecosystem. In some places, to build a reservoir will make the effiency of water utilization, anyway, the flood and low-flow process of ricers is weakered at the same time. Because of that, some species which live based on it may be damaged. The construction of large-soale will produce obvious impact on the habitat since reservoir impoundment. Because of the slow down speed of the rivers in reservoir area, the water receiving sewage ability and self-purification capacity will reduce. Besides, many floodplain is submerged by reservoir, it will cause the problem that may farmland will lose. The hydroelectric station also has the influence to the climate. It will impact on the temperature, the rain fall and so on. Moreover, it may induce geological such as earthquake and landslide. â… £ Future development of hydroelectric Though the hydroelectric stations have some bad effects, anyway people now are trying to develop it. It has several advantages. It has the low power cost. It is known to people that many plants can service for 50 to 100 years. It is much cheaper than fossil fuels. It can also reduce the CO2 emission which makes contribution to alleviate the green house effect. And it is suitable for industrial application and flexiable to use. What is more, it also provide facilities for water sports, and some plants even become tourist attractions themselves. In all, people are coming to realize the importance of hydroelectric. They have begun to try their best to develop it. It can be predicted that the hydroelectric will develop faster and faster, not only in Philippines or China, but also around the world.

Break of Day in the Trenches Analysis Essay

In the poem, â€Å"Break of Day in the Trenches†, the author, Isaac Rosenberg shows the theme that endless conflict leads emotionally numb soldiers to snap, through the literary devices, tone and personification. Tone is used by Rosenberg to furthermore reveal the theme in this poem. The two that he uses are musing and contemplative tones. The author uses the air of musing in this poem throughout the beginning few lines of the poem. When a soldier is immersed into war they are exposed to the death of their friends and peers, they are taken from their family, and they are forced to repel any emotions. The soldier who is telling his story is sitting in the war trench at sunrise or in his words, the â€Å"druid Time†. The Druids are an ancient civilization who at sunrise made sacrifices to their gods. This leads readers to believe that the soldier is sitting among what could be interpreted the human â€Å"sacrifices† that war had taken. Around him there are soldiers lying dead for seemingly no good reason. To be talking in the tone of curiosity rather than pain and horror in that situation, it shows that he has numbed himself to the feelings that would naturally come to him because he is so used to seeing the display of death. The other tone that is used by the author is a tone of contemplation. Rosenberg shifts from talking to himself, to directly addressing the rat, asking questions and drawing his own conclusions. The soldier gets more and more demanding of the rat as the poem goes on, eventually asking it, what do the eyes of mankind say. The soldier uses the rat to ask all of these questions because he knows he shouldn’t be thinking emotionally. He can’t control himself and he has to let off steam by talking to a rat, which can’t respond or judge him. He then has a final break in his mind, using the death of a poppy to symbolize death of soldiers. He says, â€Å"Poppies whose roots are in man’s veins/ Drop and are ever dropping;/ But mine in my ear is safe-/ Just a little while white with the dust. † He had just picked the poppy from the parapet, taking it from its nutrients causing it to stop growing. This is ironic because the flower, though safe from being trampled, is already a dying cause, just like him. He gives up and lets know, even while knowing he is going to die, he chooses to numb his emotions again, and move on till his day comes. The shift from controlled and nonchalant to inquisition and back to control shows the struggle that soldiers had to face and the fact that the idea of emotional numbness is flawed. Personification is rarely used in this poem, but when it is used it has powerful meaning behind it. The two areas personification is used is when he talks about the sleeping green and the queer, sardonic, and droll rat. The green grass is given the personification of sleeping to reflect the death of the soldiers who lay on it. As a whole, the soldier is referring to No Man’s Land. The second personification is used on the rat. The rat is given the human qualities of being sarcastic, odd, and amusing. The idea of personification is to give a feeling to something incapable of human-like qualities. Feeling shouldn’t be a part of a soldier’s thoughts. This goes to show that the use of personification is a way for the soldier to reflect his feelings on something else. War is too emotionally scarring for you to not have an emotional reaction to it. In essence, the poem, â€Å"Break of Day in the Trenches†, Isaac Rosenberg uses tone and personification to show the theme that endless conflict makes it impossible for soldiers to completely suppress their emotions. The shifts in tone that the author wrote showed the struggle from controlled to a mix of emotions, then back to control and acceptance. The personification shows that the soldier needed something to project his feelings onto because he couldn’t handle not being allowed to talk about them, causing him to talk to a rat for consolation.

Essay about Media’s Impact on Beauty and Body Image of...

It’s difficult to envision a world where idealized female imagery is not plastered everywhere, but our present circumstance is a relatively new occurrence. Before the mass media existed, our ideas of beauty were restricted to our own communities. Until the introduction of photography in 1839, people were not exposed to real-life images of faces and bodies. Most people did not even own mirrors. Today, however, we are more obsessed with our appearance than ever before. But the concern about appearance is quite normal and understandable given society’s standards. According to Jane Kilborne, â€Å"Every period of history has had its own standards of what is and is not beautiful, and every contemporary society has its own distinctive concept of the†¦show more content†¦(Heubeck 2006) For many young people, especially girls, the ideal continues to chase them as they grow into young women. Young girls begin to internalize the stereotypes and judge themselves by medi a’s impossible standards. The power that the media holds in impacting the lives of young girls is detrimental and eventually affects their body image, their satisfaction of their own body, and portrayal of their body as an object. Researchers have discovered that â€Å"ongoing exposure to certain ideas can shape and distort our perceptions on reality.† (Mintz 2007) Because young girls are subjected to a constant display of beautiful people in the media, they have developed a negative body image of themselves. Those who have a negative body image perceive their body as being unattractive or even hideous compared to others, while those with a positive body image will see themselves as attractive, or will at least accept themselves and be comfortable in their own skin. During adolescence, negative body image is especially harmful because of the quick changes both physically and mentally occurring during puberty. Also, young girls are becoming more and more exposed to the media and the media keeps getting more and more provocative. Young girls are looking to women with unrealistic body shapes as role models.
