Renewable Energy (Hydropower)
The first time hydropower was used was in 1880 to generate 16 lamps at a wolverine chair factory in Grand Rapids Michigan. In the United States, hydroelectric plants opened near Appleton, Wisconsin on the Fox River on September 30, 1882. At that time, the only fuel used to make electricity was coal because of its abundance and low cost. People knew about hydroelectric power but the only places you could do that is by a water source. Hydropower became more popular when technology could send electricity long distances.
To make hydropower, you have to direct moving water into pipes known as penstock. The swiftly flowing water in big rivers determines the energy produced or waterfalls, like the Columbia River or Niagara Falls. After the moving water is directed into the penstock, it pushes against the blades in the turbine to spin a generator that produces electricity. The other way to get hydropower is a storage system where water is collected by dams and will direct water into the penstock to turn the generator when the demand for electricity is high.
The water being held back by the dam becomes lakes used for boating and fishing. The rivers beyond the dam become whitewater rafting and kayaking spots. An example of this is the Hoover dam, made in 1936 between Arizona and Nevada. This dam created lake 110 miles long called Lake Mead, offering water sports and fishing. Almost all of the hydroelectricity made in the United States is made in nine states, Washington, California, Oregon, New York, Tennessee, South Carolina, South Dakota, Arkansas, and Nevada.
Hydropower is an ideal fuel because it is renewable and almost free, having no waste products, and does not pollute the water or air. A negative about hydropower is how it changes the environment and alters the natural habitats. An example of the negative effect on nature by a dam was when the salmon was blocked from their spawning grounds upstream.
The Hoover Dam turbines provide a great amount of electricity to those living in the states of California, Arizona, and Nevada. The water level of Lake Mead currently affects the dam’s ability to provide power from the large sized turbines. When the water level of Lake Mead goes down from conditions affecting it, the dam’s ability to provide power directly affects the power companies supplying consumers. Fortunately, the water levels gained back some of that full amount while still shy of where it once existed. As stated, “But the increased elevation isn’t enough to reopen any of the four boat launch ramps closed in the past decade, Holland said” (Shine, C., 2011, para. 9). This definitely indicates that there is currently promise to recovering with close to the original levels even though it may not be excessively soon.
Whitman saw America as a land of opportunity, yet realized that the Civil War was a stain on its potential. In his poetry, the writer was able to demonstrate both the country’s positives and downfalls, which is epitomized in “O Captain! My Captain!” In this tribute to Abraham Lincoln, Whitman transitions from “Exult O shores, and ring O bells!”
Walt Whitman’s "Crossing Brooklyn Ferry” was written before the construction of the Brooklyn Bridge. It was originally published in 1856 and was titled “Sun Down Poem.” Whitman revised the poem and republished it in the 1860 edition of Leaves of Grass and under its final title, “Crossing Brooklyn Ferry.” The Brooklyn Bridge wouldn’t be completed for another twenty-three years. The Brooklyn Ferry was how commuters would get from Manhattan to Brooklyn or vice versa. During the time that Whitman was writing this poem, the American Civil War was taking place, which was a time when America was deeply divided. Whitman wrote his poem with a clear message of unity and how they could come together with experiences that they have shared.
At first glance, this ferry is only that; a boat crossing from one destination to another. However, this is not the story that Whitman was trying to tell. The Brooklyn Ferry is so much more than what it appears. It is the journey between one world to the next. It takes one man’s life and gives it a new beginning as it reaches the other side. The ferry is an essential element to the poem. It represents a human

The poem opens with the line “ Ashes of soldiers North or South” (Whitman 1). Whitman is trying to express the idea that whether it be a Union soldier or a southern one, their lives mattered. He cares for the soldiers, since he was a nurse during the Civil War. Whitman volunteered during the war and as a “private man tending the wounded in the hospital wards” (Whitman 1). Since he was a caretaker during the war, Whitman had compassion for their lives and all their bravery. He realizes that these deceased soldiers are now voiceless and decides to “chant this chant of my silent soul in the name of all dead / soldiers.” (Whitman 1). Since the soldiers are no longer alive, Whitman takes it upon himself to be the voice. Whitman pays respect to soldiers from both the Union and Confederacy
The Albigensian Crusade envisioned to take out the Catharism harvesting of Christianity in France. In the Fifth Crusade, Pope Innocent III prior too his demise in 1216, the Crusaders attacked Egypt from both area and ocean, however were compelled to surrender to Muslim protections hammered by Saladin's nephew, Al-Malik Al-Kamil. During the extremity of the thirteenth century, meetings of Crusaders observed to create development in the Holy Land via little contests rather than enormous ones that would interrupt the Muslims monarchs in the
While the poem can be termed to be democratic, both in subject matter and its language, Whitman is viewed to be cataloging the ‘new’ America that he is seeing around him. The poem includes subject matter such as relationships, patriotism, heroes, family and ancestors, and a view on social commentaries too.
Walt Whitman was arguable one of the most influential poets during the Civil War era. Though never directly involved in war, Whitman was able to talk about the war in a more insightful way than many poets at the time could. Whitman was most active in writing during the times before and after the war, choosing to dedicate himself to helping wounded soldiers during the war instead. Walt Whitman’s poetry reflects the progression of his philosophy of America: his initial view of America was uplifting, represented in his Pre-Civil war poems and while the Civil War poetry presents the degradation of American society, Whitman’s final poetry returns to a realistic, optimistic view for America.
How exactly does hydropower work, though? As it turns out, dams are the main source of harvesting energy via hydropower. There are about 80,000 dams in the United States, although not all are active producers of power. There are four main types of hydropower facilities, which all require turbines: impoundment, diversion, run-of-river, and pumped storage. Also, there are two main types of hydro turbines: impulse turbines and reaction turbines ("Hydropower…”).
Fossil fuels are known as non-renewable resources; the amount in the Earth is limited. On the other hand, renewable sources of energy, like solar and wind, are those that will not be depleted despite their continued use. However, solar energy is difficult to harness and wind energy is not very efficient. The clear choice of renewable energy is water. The Earth has plenty of water to use for power. After all, it is because of its great quantity of water that Earth is nicknamed the “blue planet.” Hydropower is entirely renewable because it is driven by the natural Water Cycle. Lakes and rivers that are used for hydropower will not simply run out because they are constantly being refilled by rainwater. In addition to being renewable, hydropower is superior to other energy sources because it is completely clean of carbon emissions. Once fully functional, dams power themselves and give off no excess gases. Power plants burn coal and pour unthinkable amounts of greenhouse gases into air. Hydroelectric power is a clean, renewable source of
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
There are three parts to a typical hydropower plant. The first part is an electric plant where electricity is produced. The second is a dam that open and closes to control the flow of water. Water behind the dam goes into an intake and is pushed against blades in a turbine which causes them to turn. Then the turbine rotates a generator to create electricity.
Hydroelectricity is a known renewable energy resource that provides substantial benefits for our wealth, our health, and for our global economy. There are five types of renewable energy we can use on a daily basis throughout our lives, but the most widely installed form of renewable energy is hydroelectricity. Hydroelectricity is electricity created by converting the kinetic energy of flowing water. Best thing about this source of energy is that it’s timeless and renewable, which means it will never run out, however we had to figure ways to store this energy. In order for them to harness this energy for other people, they had to build generators that convert all the potential energy of rapid moving water into electrical energy.
