Energy from the Wind

The world today is run by energy. Scientists are constantly thinking of new ways to create energy. The creation of energy might be the most valuable creation ever. Something that is even more valuable than energy is renewable energy. Renewable energy is any natural resource that can replenish itself naturally over time, as wood or solar energy; also called renewable energy, renewable energy resource, and renewable natural resource. The principle behind Wind Power is the conversion of kinetic energy of wind to electrical energy. The source of the power isn’t just the wind. An uneven heating of the earth’s surface by the sun with the pressure difference in the atmosphere creates the creation of wind. The devices that are used are Wind turbines that are driven by air pushing on the blades which turns the generator to allow the production of electricity. The power depends on the length of the turbine blades and the wind speeds. The conversion rate is 45 percent. The Windmill has been used ever since 500 AD. It was one of the earliest and most important instrument for power at its time. Wind energy has many advantages and disadvantages. With most things in life, a positive usually will be followed by a negative.

Wind Power has been used first by the Persians. The created the idea of the Windmill. Between the years of five hundred to nine hundred A.D. the vertical axis windmills were created. The Persians used these Mills for grinding grain, which was their most important crop at the time. Four hundred years later the English upgraded to the Post Mills. The difference was that the axis of the windmill was now horizontal, not vertical. It was used for grinding grain and pumping water. In th...

...t is important the renewable resources are used. The positives outnumber the negatives. From environment to cost, renewable resources are looking better and better than fossil fuels. One day we will run out of fossil fuels and will have to turn to renewable energy, but how about we learn as much as we can about wind energy so when the time comes wind will be used to its fullest possibilities.

    Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.

  • Robert Frost-The road not taken

    617 Words  | 2 Pages

    Life has many roads you can take and it’s which ones you choose to follow that will shape your future forever. That is what I always take from this great Frost poem. He sees two roads both being equally appealing, but selects the one less traveled and how it makes his life unique. This poem is one of few that I do care for myself. It shows a man whose come to a point in his life where he has to decide what he will do with it. This is a point in our lives that everyone will come to and a somewhat difficult challenge for many. We have the many options ahead of us and must try and look ahead to what will come to decide our future. “And be one traveler, long I stood and looked down one as far as I could.” I think this was a time in Frost’s life when he had just moved to London and was looking back at the choices he had made. He quit trying the Derry farm and sold it and moved to London to write. This was an awfully risky thing to do at this point with a wife and kids, but it shows his approval in retrospect. “Then took the other, just as fair, and having perhaps the better claim, because it was grassy and wanted wear.” This shows that he choose a path that many choose to not to. He selected a harder path in life that could have been a devastating mistake given his situation in life.

    Throughout time, humans have always been required to make difficult, life-changing decisions often in their lives. Frequently they may wonder if they took the right decision, or if they would have a better life had they decided otherwise. Frost’s poem, “The Road Not Taken”, is a recollection of the speaker’s decision on which of two roads to take, this being a metaphor of a person making decisions in their life. These decisions obviously must be different, else they would be easy to make. In the poem, however, the roads look “about the same” making it an even more difficult decision for the speaker.

    “The Road Not Taken” basically talks about the many obstacles in life, the choices and decisions that you have to make, and how the things you choose affects everything in your life and in your future. Frost also tells how he chose a path or a road, that even though was odd or different from everyone else’s, he went on with his instincts and decided that it was the right choice. He tells how one single decision in life can make huge or drastic differences being either good or bad. This was expressed when he said “Two roads diverged in a wood, and I - I took the one less traveled by, And that has made all the difference.”

  • The Other Road in Robert Frost's The Road Not Taken

    David Wyatt writes, "Nowhere in Frost is the tension between surprise and anticipation, wayward experience and the form into which it is cast or forecast, more acute than in 'The Road Not Taken'" (129). As the poem is read, one cannot help but be pulled into the questions of which road will be chosen, how they differ, and what will become of the traveler. Perhaps some hope to find guidance for their own journeys by seeking answers in Frost's work. According to Michael Meyer, "The speaker's reflections about his choice are as central to an understanding of the poem as the choice itself." (97) Frost himself admits, "it's a tricky poem, very tricky." (Pack 10)

    In his piece The Road Not Taken, Robert Frost utilizes metaphors and imagery to successfully convey the importance of taking the riskier, less common, and more exciting path in life. Throughout the piece, Frost provides the reader with several examples of metaphors that he uses in order to emphasize the different paths one must choose to take within their lifetime. In his poem, Frost is confronted by two paths, and urges every individual to take the one "less travelled by" (Frost 19). The paths symbolize different choices an individual must make in life. He dwells on his decision for a lengthy period of time as he compares each path, but reaches the conclusion that each path appears attractive to him in their own way. Changes that occur in life also appear captivating and exciting, but the only way to know what truly awaits one in the future, they must *create* the courage to trust one choice. The poet also recognizes that most changes are irreversible, and encourages the reader to make the most out of each choice, knowing that he, as well as everyone else, can

    Frost gives just enough details in his writing to provide the viewers with a clear picture but allows them the freedom to create their own interpretations. One of the main things that make this poem attractive is the dilemma of picking a path. People immediately relate to that dilemma because most people face it numerous times throughout their lives. The Paths in the woods and forks in roads are metaphors for the many problems and decisions that fill one’s life. This poem says that we are free to choose, but we do not really know what we are choosing between. It does not say to take the path less traveled by nor take the path that is more traveled. The speaker knows that he will either second guess the decision somewhere down the line or wonder what was down the other path. In reality there is no right path, only the chosen path and the other path.

    In conclusion, Frost uses the symbolism and tone to display the theme to his readers. He teaches the lesson that although choosing the harder path may be more challenging, it also has the chance of being more worthwhile. By using symbolism to metaphorically represent the two choices and the difficulty of the narrators decision, Frost illustrates to his audience that the right choice may not always be clear. However, Frost uses tone to show that even though the narrator was unsure of his decision at first, it all worked out in the end. The theme of life decisions is so relatable to its audience because everyone faces a difficult at some point, and Frost makes the point that hard decisions are a part of life, as are doubt and regret, but making the most out of the circumstances is the best way to be pleased with the outcome.

  • Wind Power And Solar Energy

    1042 Words  | 3 Pages

    Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
