Nuclear energy originates from the splitting of uranium atoms in a process called fission. At a power plant, the fission process is used to generate heat for producing steam, which is used by a turbine to generate electricity. About 440 nuclear reactors are used around the world to produce about 17% of the worlds electricity. The USA has 100 nuclear power reactors in 31 states, operated by 30 different power companies. Since 2001 these plants have achieved an average capacity factor of over 90%, generating up to 807 billion kWh per year and accounting for 20% of total electricity generated. Capacity factor has risen from 50% in the early 1970s, to 70% in 1991, and it passed 90% in 2002, remaining at around this level since. The industry invests about $7.5 billion per year in maintenance and upgrades of these."NuScale SMR Wins Second DoE Funding round." Nuclear Power in the USA. N.p., n.d. Web. 16 Dec. 2013.
With the process of nuclear energy, there is pollution in the form of radioactive waste and the possibility of radiation leakage or a plant meltdown. There are problems and dangers, which could lead to possible accidents. For example, the power stations are run manually and human error could possibly lead to accidents and disasters. And even though the cost are cheaper in the long run, the reactors also have a very expensive capital outlay in the beginning. Duke Energy is proposing to build a nuclear power plant in North Carolina. I feel that Duke Energy SHOULD’NT build a nuclear energy power plant in North Carolina, and here are my reasons why.
Nuclear power is extremely costly.

...n. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun's heat also drives the winds, whose energy, is captured with wind turbines. Then, the winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydroelectric power.Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called bioenergy."Types of Renewable Energy." Why Is Renewable Energy Important? N.p., n.d. Web. 16 Dec. 2013.

- The acidity or alkalinity level is dictated by the pH, potential of hydrogen, scale. Soil pH or soil reaction is an implication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is characterized as the negative logarithm of the hydrogen particle fixation. As the measure of hydrogen particles in the soil builds the soil pH diminishes along these lines getting to be more acidic. From pH 7 to 0 the soil is progressively more acidic and from pH 7 to 14 the soil is progressively more alkaline or basic.... [tags: plant development, alkalinity of soil]

- “To Build a Fire” written by Jack London can truly be considered as a work of art. With themes anyone can relate to, such as survival and man versus nature, it is a great short story for anyone looking for something to read. Everyone knows a dog is a man’s best friend, but what happens when it is man versus dog. When survival of the fittest kicks in, the fittest truly shows. In “To Build a Fire”, Jack London expresses various elements of literature to really get the reader involved in the story.... [tags: To Build a Fire ]

- Significance of the Dog in To Build a Fire With regard to Jack London's, "To Build a Fire", I will attempt to analyze the significance of the dog, however in doing so I will need to discuss not only the dog, but the man and nature as well, because they all impact one another with equal significance. It is my opinion that throughout most of the story the dog is to represent a living creatures innate instincts (although I was lead to question this at the end), the man represents desire and sheer will (although he also shows many signs of repressed instinct), and nature represents the force which triggers instinctual behavior (perhaps a temporary barrier if obeyed...

- Toyota's Decision to Build a Plant in France Background In late 1996, Toyota began to look at the whole of western Europe for a site for its ultra-modern plant. Belgium, the Czech Republic, France, Germany, Poland and the UK all seemed to be the most promising investment recipient, but the list was quickly left a head-to-head battle between Europe's oldest foreign investment rivals - France and the United Kingdom. At first, the UK seemed the obvious choice. Toyota had its only European car assembly plant at Burnaston, in the UK's Midlands, where a skilled workforce and well-established automotive infrastructure and cluster of related firms are available....

- Evolution Most botanists believe that the Pteridophytes also known as ferns are descendants of the Rhyniopsida, an extinct group of free-sporing plants which originated in the Silurian period (about 430 million years ago) and went extinct in the mid-Devonian period (about 370 million years ago). Physiology Ferns has no flowers, no seeds, and no fruits. A fern is defined as a cryptogam which means a plant that has no true flowers or seeds. With sporangia, a receptacle in which asexual spores are formed evolving from the leaf.... [tags: Fern, Plant, Species, Leaf]

- Introduction Plants exhibit exceptionally intelligent behaviour when it comes to interactions with their environment. They can detect perceived threats, then convey warning signals to other plants via chemical signaling. Forewarned plants will then assemble their defenses against these potential threats, thus, increasing their chance of survival and reproduction. Communication and competition are common occurrences among the plant world. Another brilliantly, almost inconceivable capability plants possess is the ability to recognize coexisting family members within their home range....

- Foreshadowing in To Build a Fire In the story "To Build a Fire" by Jack London, foreshadowing is often used. In this story foreshadowing is an effective way to build up a climax. The foreshadowing is both shown by the environment and things the characters say. An example of environmental foreshadowing was when it said, "Fifty degrees below zero stood for a bite of frost that hurt and that must be guarded against.... "Another example was when the man's "fire was blotted out." These examples show that the cold will be the man's doom, but foreshadow only by telling the necessary details....
