The Energy Of Solar Energy - 1462 Words

According to the National Institute for Energy Research and the U.S. Energy Information Administration, solar energy makes up only 0.5% of total energy consumption in the United States, and over 65% of consumed energy is natural gas and petroleum. (2016) These statistics show that nearly two-thirds of the energy the United States uses is not only non-renewable but the processess of harnessing it also causes pollution. Solar Energy is energy that is transferred through solar radiation in the form of electromagnetic energy. In the transference of solar radiation to Earth from the Sun, only one billionth of this energy arrives at Earth s surface. A joule is the equivalence of one watt of power that is created through exertion for one second. One trillion watts of this generated energy is known as a terawatt. As Haugen and Musser (2012), examined types of alternative, renewable energy sources, they looked at hydro-power. They said that it, â€Å"is the most used renewable energy sourc e used in the United States. It accounted for almost 80 percent of the renewable energy and 9 percent of the total electricity generated in the United States in 2008.† This shows that solar is not the only option for renewable energy, nor is it the most used. Solar power, however, does not instigate change in the environment as hydro-power does. In order for many of the dams to be created to instigate the use of hydro-power, waterways have to be rerouted or otherwise altered from their naturalShow MoreRelatedThe Energy Of Solar Energy1687 Words   |  7 Pagesanalyses of solar energy deployment contained in the Word Energy Outlook, Energy Technology Perspectives and several IEA Technology Roadmaps.

Essay on Comparing the Heroes in The Dream of the Rood...

The Heroes in The Dream of the Rood and Beowulf In The Dream of the Rood, the poet has added elements of the idealized heroic death (as exemplified in Beowulf and The Battle of Maldon) to the crucifixion. He has also eliminated details of the story that tend to render Christ as a figure of pathos, in order to further Christs identification with the other glorious warriors Anglo-Saxon poems. When a hero meets his death, for example, he is usually surrounded by faithful retainers (as is Byrhtnoth) or at least one steadfast companion, such as Beowulfs Wiglaf. The gospel clearly states that Jesus died ignobly, in the most humiliating fashion possible, and that his disciples kept themselves from Golgotha†¦show more content†¦How can a man die honorably without treasure? The poet does not mention that Christ dies to fulfill a prophecy, one that is unavoidable and that he therefore calmly accepts. The notion of letting fate do its work doesnt seem to be on any of the other heroes agendas, either. Beowulf, for example, suspects that the dragons laying waste to his kingdom may indeed be divine punishment -- but that doesnt stop him from going to its barrow and stabbing the creature in the belly. In fact, Beowulf clearly states It is a mystery where a courageous man will meet his fated end. . . [ll. 3063-4] . Interestingly, in Maldon, the ones on the battlefield who are described as fated to die are always the Vikings, the barbarians. On page 57, a Viking warriors death is recounted thus: The fated warrior fell to earth. Whereas Byrhtnoths sisters son chose death in battle, on the same page. The delineation is clear: a hero dies in battle, by choice; others let fate roll over them. The designation fated is never applied to the valorous. A medieval hero always seeks his own death, if by his sacrifice his kinsmen will benefit. This is why Beowulf willingly enters the den of his third and final monster: Now the edge of the sword, hand and hard blade, must fight for treasure. [ll. 2508-9] Treasure means security for his people; therefore he goes, refusing all help, because it is his duty to do well by his kingdom.

We will write a custom essay sample on Analysis of Documentary † the End of the Line† or any similar topic only for you Order Now But the whole film is based on a book By Charles Clover himself a fisherman who tells us about his happiness when he first caught a big great salmon . Other researchers , scientists and just fishermen travel around the world to get people to pay attention to the problem of factory fishing which has reduced and made some fish species extinct . In many ways this film is like a funeral for fish . The scientists predict that if we continue fishing as we are now , we will see the end of most seafood by 2048 . The film takes us around the fishing world to the places like Alaska , Canada , Senegal and Bahamas . The film presentation is less like an investigation but more about discovering the guilty criminals because of which fish is disappearing . The film defines them and we listen to expert witnesses who explains us about why those people are guilty . The documentary opens on a colourful ecosystem that immerses us into the beauty of the underwater world , shows us how this world swarming with life and how it is full of various kinds of fish . Credits calmly fade in and out of the picture as beautiful fish dart in and out of coral reefs, filling the screen with happiness and vibrancy. The credits finish rolling and the music that has been playing in the background transforms from cheerful to suspenseful and dramatic . Drab, gray colors suddenly replace the bright ones, and short scenes begin to flash in sync with the music. Huge boats charge through the sea like a tank rolling into a battlefield. A fisherman’s silhouette appears and he brandishes a knife, plunghing it into a flopping fish. Red, vibrant blood squirts everywhere, even splashing onto the screen, and it drips from the knife of the fisherman . Quick cuts , dramatic close-ups , emotional music , and vivid details are all characteristics of this film . Colors and music in this documentary , that were mentiod earlier , are directed to convey a message of hatred and disgust towards anglers , even before a single word is said . The violent shots of fish being hit in the head, nets filled with flopping fish (complete with an unpleasant slapping sound), and knives creating gushing stab wounds in huge tuna are accompanied by slow, dramatic music and music that could be straight from a horror movie. One shot from within an underwater net shows a few fish with panicked faces, eyes wide, and mouths open, lunging toward the camera as if screaming, â€Å"Let me out! .

The diction in this film is mostly voice-over and interviewees . The definite attempt of voice-over is to man ipulate the emotions of audience . What about the interwiewees , many of them are very passionate about the issues presented in this documentary , and it shows in the word choice that they use . In the interviews what they do is that they are encouraging and persuading people to stop consuming fish in such big amounts as we do now , to stop fishing ilegally or reduce catch of fish , to prevent this tradegy , otherwise we will see the end of seafood . They also represent us the statistics that are intimidating . Those statistics and interwievs create a horrifying atmosphere and mood . The method of this film is to shock audience . This is the great move to engage people , because it is a shock and fear that makes people be more serious and change the way they think and their worldview . And the dramatic music only feeds those feelings . As it was mentioned earlier the film takes part in different parts of the world . For example in Africa the fishing business is very well developed , but as they were asborbing and catching fish in large quantities this led them to a shotage of fish as well as to the loss of jobs . Since fish and fishing itself for them is one of the most important kinds of food and job , many fishermen were forced to go to Europe to infiltrate their families . And this is already one of the examples that the fish is being extincted . Another example that fish is being extincted is that some corporations and fishermen cheat because they can and don’t get caught . In the documentary , a passionate Mielgo described the role of Mitsubishi that’s located in Japan in the decline of bluefin tuna . He believes the company is stockpiling bluefin for the day when the species will be extinct and the price of their highly regarded flesh will skyrocket. The bluefin situation demonstrates what multinational corporations, international fishing policy, and consumer demand can do to a wild species. The film gives us a lot of information, using statistics, scientists, fishermen, and people associated with the fishing industry, which makes us feel truthfully about this film and believe it and to take their message and really try to make a difference in the underwater world . All in all the main purpose of this film is to reach people , to make them to imagine an ocean without fish . Imagine their meals without seafood . Imagine the global consequences .
