...Uranium is a common radioactive element found in abundance mainly in the Earth’s crust. Uranium-235 (U-235) is the most significant variety of uranium, used in the production of nuclear power and nuclear weapons. Nuclear power is commonly recognized as a potentially problematic and, to a certain degree, dangerous source of generating electrical energy. However, the manageability and advantages of uranium mining trigger a debate within the public: do the benefits of uranium mining outweigh the potential risks? Uranium is naturally radioactive in all of its isotopes. Uranium is the heaviest naturally occurring radioactive element and undergoes radioactive decay. An atom of a radioactive isotope will spo-ntaneously decay into another element by...

...threat of new entrants is very low. On the cost side, entering the market of uranium mining is extremely expensive due to exploration cost and initial capital. Also, the government has very strict regulations on nuclear mining and usage. Since Federal government enforces the environment law on energy sector, companies, which want to entry into nuclear energy industry, need to ensure the environment safety before the business launched. According to Cameco, “We study the environment around the project area to gain an understanding of potential effects on air and water quality, wildlife, plants, noise, human health, aboriginal activities, and the use of land and natural resources.”(Cameco, 2010) This is not an easy industry to penetrate, especially since the industry has been fulfilled by numerous major players such as Cameco, Nuchem, and Areva. The majority of uranium resource has been controlled by the existing operators. In 2011, eight companies marketed 85% of the world’s uranium mine production. (World Uranium Ming, 2012) Thus, the barriers to entry the current nuclear industry are intense. Threat of substitutes Respect to the main product that Cameco, Uranium currently are principle to produce nuclear weapon and nuclear energy. The nuclear weapon industry merely has substitution from other bomb industries. However, on the energy side, there are a huge amount of energy sources can substitute uranium to generate electricity and heat. In 2008, Coal (48.7%) and Natural gas (21...

...form to a different form are from one object to another. This energy law applies use which is taken energy and changing into a different form, one example is Solar Energy; energy from the sun can be changed in to useable energy for homes, schools, hospitals etc. The energy conservation law also applies to considering that some energy is wasted during the change, it’s impossible to change energy and not waste some of it. Cons and Pros of fossil fuel and oil, natural gas, and coal are pros consist of higher efficiency, it’s less expensive than none conventional reason being it’s easy to change and process them also has the ability to power the globe, the cons of fossil fuels are they have the biggest emitters of greenhouse gases which is mainly the reason for climate change and global warming. Coal mining creates quakes that’s also believed, they are none renewable so that makes it the biggest con. Nuclear Energy creates small amounts of oxygen and it generates huge amounts of electrical energy. Waste is radioactive when produced in these plants. Uranium is the energy source which has a limited supply; nuclear power plants could encourage terrorist attacks. This source of energy is renewable. Solar energy it provides energy to homes with solar panels and there’s no up keep required most of the energy is produced in the light because the panels become larger, these panels are very costly.

...energy, wind power, water (hydro) power, and bioconversion (biofuel) these laws could allow the possibility of tax incentives. The use of different types of natural energy can pave the way for a greener earth. Although, some may argue that there are pros and cons of such energy. In this paper we will be discussing these pros and cons as well as two provisions of the Energy Policy Act, 2005, including its tax incentives. 1.) The law of conservation of energy states that energy may neither be created nor destroyed (The law of conservation of energy, n.d). 2.) The pros and cons of fossil fuel: oil, natural gas, and coal. The pros are its high efficient, cheaper than non-conventional forms of energy because it is easy to extract and process them and it the potential to power the entire globe. The cons are Fossil fuels are believed to be the largest emitters of greenhouse gases, responsible for global warming and climate change. It is also believed that coal mining creates earthquakes. The biggest con of all is that they are non-renewable. Nuclear Energy creates little amount of CO2 and it can generate a great amount of electrical energy in one single plant. But these plants produce radioactive waste; the energy source is uranium which there is limited supply. Also nuclear power plants could entice terrorist to attack. Solar energy is renewable source of energy, its clean, provides energy to homes with the use solar panels and its maintenance free. This energy produce the majority...

...good news is there are many technologies that exist today to allow cars to operate more efficiently and use less gas. In order to reduce the amount of toxins in the atmosphere, older power plants need to be modernized and we need to reduce our electricity by putting into practice energy efficiency, these are just some suggestions to lowering the levels of CO2, we have to make sure they are implemented. Politicians are especially attracted to the restoration of nuclear power as a possible solution to averting global warming. When the subject of global warming is discussed and the methods to reduce it, it is out of the ordinary that the focus is put on the pros of nuclear power generation, and its disadvantages are rarely mentioned. As the discussion of renewing nuclear power is examined, the subject over the pros and cons top the list of dispute. Regardless of the apprehensions and concerns over nuclear energy, there are...

...Nuclear Energy Research Paper Global warming is a major issue in today’s world that affects many people, animals, economies, and society as a whole. What is global warming? Global warming is the rising average temperature of Earth’s atmosphere and oceans and its projected continuation. It’s been constantly rising over the past 100 years because of major contributions which include: greenhouse gases (especially CO2) being emitted, industrialization, burning of fossil fuels, and the increase in population. Global warming was first discovered in 1896 by a Swedish scientist named Svante Arrhenius who proposed an idea that there is a relation between atmospheric carbon dioxide concentrations and temperature. He later then described, by comparing carbon dioxide levels, infrared absorption, surface temperature of the earth, and human activity, that global warming would rise. Other scientists didn’t believe this idea stating that natural forces would cancel out human activity that releases carbon dioxide. It wasn’t until 1988 that it was finally acknowledged that global warming is present because of how much warmer it was than the 1800s. Since then, the Intergovernmental Panel on Climate Change was founded which looks at scientific, technical, and socio-economic information that relates to human induced climate change and figures out plans and ideas to decrease and slow down the rate at which the climate is getting hotter. However, there are still disagreements to this day whether or...

...The development of clean energy sources is essential if the United States is to reduce greenhouse gases and slow global warming. Today, electrical generation is responsible for 41 percent of the Unites States’ carbon dioxide emissions. The majority of electrical generation comes from conventional, fossil fuel run, power plants, with nuclear power being the leading alternative. But neither source is renewable or sustainable, furthermore, nuclear energy is beset with many problems. Alternative energy refers to energy sources which are not based on the burning of fossil fuels or the splitting of atoms. There are numerous reasons for supporting alternative energy development: lower air and water pollution, reduce land disruption through mining and drilling, reduce solid and hazardous waste production and greenhouse gas emission. Only renewable energy options offer long-term hope for sustainability. Several alternative energy options already exist, such as wind, solar, wave and geothermal. I believe that we have the technology today, to power the world sustainably. Presently, nuclear energy is responsible for approximately 16 percent of the world’s electricity; in the U.S. it is the second leading source of energy next to coal. Nuclear energy is often looked at as a cleaner alternative to burning fossil fuels due to the low amounts of greenhouse gases emitted by the power plants. But the use of nuclear technology is full of security and waste-disposal problems. Despite high...

...3, the Gaia hypothesis is introduced. It addresses two hypotheses; (1) life, since its inception, has greatly affected the planetary environment and (2) life has altered Earth’s environment in ways that have allowed life to persist. Do you agree with these two hypotheses? Why or why not? Energy and Food Supplies. The underlying theme of this course is energy. As a whole, the global society needs to find ways to reduce our energy consumption. The food pyramid is a prime example of energy transfer within individual ecosystems and the biosphere. As you increase the trophic levels, a greater amount of energy is lost. Some environmentalists argue that humans should eat a vegetarian diet in order to conserve energy. What are some of the pros and cons of this action? Consider the impact to the agricultural industry? How low on the food chain do you eat? Would you consider eating lower? Model Ecosystems. Review the virtual lab in Model Ecosystems. Within this laboratory exercise you will categorize various organisms into the correct trophic level for five different ecosystems. Once completed, you will calculate the amount of energy transferred between levels. Record your observations. Answer the journal questions and upload it as a Word document into the online course.

In the 1700s, people found that it would heat cleaner and hotter than wood charcoal. The Industrial Revolutions overwhelming need for energy to run the new technologies providing the real opportunity for coal to dominant as a worldwide supplier of energy. (A brief history of coal use). As other sources of energy was discovered the use of coal diminished. However, 4 decades ago it became popular again as an energy source. The 1970’s brought about an oil crisis that showed industrialized countries that any disruption in the petroleum supply line would send a shockwave through energy production. (Morse, 2012). Even though coal...

Economic Challenges Facing Contemporary Business Rudyanto Wijaya/iStockphoto Copyright ©2012 John Wiley & Sons, Inc. NASCAR Tries to Restart Its Engine ASCAR is widely known as the most popular spectator sport in the United States. Yet even its most diehard fans are tapping the brakes when it comes to buying tickets to their favorite speedway. Tracks in cities such as Phoenix and Talladega have reported double-digit percent declines in attendance. Just as worrisome is the fact that, instead of watching races at home, fans are changing the channel. Some critics of NASCAR blame a drop in dramatic action and a mandated car chassis design that leaves car models undifferentiated. Others say that the races are just too long and the broadcast commentary is boring. But NASCAR defenders argue that there’s another huge obstacle: the...
