...Clean Coal Daniel Robinson DeVry University Understanding what clean coal means can be confusing and the potential impact on the environment can be confusing. Hearing the words clean coal makes most of us think we have finally found a way to actually make coal a clean sustainable resource to generate our electricity. After reading “The Environmental Injustice of ‘‘Clean Coal’’: Expanding the National Conversation on Carbon Capture and Storage Technology to Include an Analysis of Potential Environmental Justice Impacts” I have come to agree with the article that coal will never be clean in a way that is feasible to anyone that has to live near these coal plants. First let’s define clean coal, clean coal as Liebert says is “The term ‘‘clean coal’’ is used to refer to burning coal in a way that reduces emissions or otherwise lessens coal’s environmental impact. ‘‘Clean coal’’ technology includes ‘‘washing’’ coal of minerals and other polluting components, gasification, and the treating of flue gases to lessen sulfur dioxide (SO2), nitrogen oxide (NOx), and mercury emissions. In the context of climate change, the term ‘‘clean coal’’ is used most frequently as shorthand for technology that burns coal more efficiently and or decreases its CO2 emissions. While some might read that and think that we could find a way to get coal without having any CO2 emissions which is not the case. While carbon capture and storage sounds like fantastic technology that has three stages of capture...

...Is "clean" coal possible? In the article it says that scientists and engineers have found a way to burn coal that won't fill the atmosphere with the fumes from it. So there for yes I do think that "clean" coal is possible. The article says that if it succeeds then about 65% of the carbon dioxide that's pumped out by the plant from reaching the atmosphere making coal about as "clean" as natural gas. The technology actually works but it is very expensive. The Kemper plant cost about $5 billion. "I don't see how we go forward without it," says Steven Chu. What do we use coal for? We primarily use coal for electricity, coal- fired plants are 38.7% of the electricity in the U.S. The average American uses 18 pounds of the fossilized plant to power...

...In my opinion, I disagree with the use of clean coal because it is nonrenewable, it devastates the environment, and produces high levels of radiation. Most people in West Virginia believe that coal should be kept alive because it is the mass of jobs, but eventually, it will run out. To begin with, there is a infinite supply of coal, and it is nonrenewable. That means that it cannot be replenished, and there is a limited supply of it. So, when all the coal is gone, there will need to be a new energy source. That source would be natural gas. It is just as cheap, if not cheaper, as clean coal. It is also nonrenewable, but is much more abundant than coal and would be in use for longer. Next, coal devastates the environment tremendously....

...Individuals are defined in several different ways such as neat or sloppy, but the word neat or sloppy may have numerous diverse meanings to others. Suzanne Britt, the author of “Neat People vs. Sloppy People,” used a direct tone to favor messy people. She also defined two individuals in today’s society by the way they keep their environments hygienic. Britt mainly focused on explaining how neat people are really sloppy and how sloppy people are really neat in their own ways. She wanted her readers to learn not to be as uptight in their lives and increase time for friends and family. In contrast to Britt, Dave Barry, the author of “Batting Clean-Up and Striking Out,” used a humorous tone in his article to exemplify how men and women have different...

...I have wondered before if I will have the chance to see the real beauty of life that I can’t find here in the busy city. But at last, after almost two hours of travel, I have seen what I am looking for; the clean river, the cold breeze, the leafy trees and the welcoming smiles of the Bago tribe, such an amazing treasures behind the mountains. Maybe it is the treasure in the end of every rainbow I see. For the pot of gold lie in the hearts of the tribe, their culture resides in the hearts and in the soul of the people. Despite of the developing municipality of Suyo, their culture remained; it is not damaged by the changes. They made sure that their culture will not die by letting the children learn in mind and heart their wonderful culture. The smiles in faces of the children showed that they really love what they are learning. It is soothing to the ears to hear their angelic voices; their ethnic dances made me forget the contemporary dances and how they beat their bamboo instruments made me feel the magic of nature. Even if I cannot understand what they are singing, I felt that they sing to show how proud they are to be part of the Bago tribe and to be thankful of all the blessings that God had given them. They gave thanks that day through a ritual, and a pig was butchered that I think is a sign of their respect and belief to the Lord. Every song they have sung reflected how they live their life in the past and now. I am amazed how they used bamboo cylinders as water containers...

...The final topic I choose is wind energy; about is it clean cheap and practical? As people know that wind energy is totally clean and just use wind to convert energy. I will figure out what is the advantage of wind energy and how to get the clean, environmental wind energy. However, people don't know how to gain wind energy; the process of converting is clean or not. Furthermore, what kind of machine like windmill can make wind energy, that’s also a question. First, I will introduce the wind energy which has different types, and their different function. Using the official language in the google to describe it, also when and why wind energy comes out. Like talking about wind energy’s history. And I will tell the wind energy machine, how to make it and how long to make it. also, how much pollution it will have during the making time. Then, I will say something about how wind energy developed and figure some celebrity in this area and their contributions. And what they didn't do and the difficult points for them and future wind energy. The next step I will talk about the wind energy in worldwide, how it works and what range does it works, then specify to different countries, such as the U.S. and China. And the result and how wind energy works efficiently in those countries. For the detail of those information, I will use website or database in library. At last, I suppose to say that the advantage and disadvantage of the wind energy. Also, compare what wind energy can...

...Sean Pack BUS 101 OCA Donatos Pizza 1. We decided to use a total of 3 employees for cooks in the kitchen at Donatos. The number of 3 would not only help us with making orders, but also with the clean duties after the rush hours. In the year or so, HR will extend our cook employees to 4 per shift for better efficiency. 2. As a Pizza/ Fast Food chain, yes we do compete for employees. We feel that the atmosphere, our salaries and benefits, interest our potential employees more than our competition. 3. After a year of being with us, we sit down with the other managers and grade an employee’s performance on a scale of 1-10. The next day we call in the employee, and let him know how he/she did last year, and how he/she can do better in the coming year. 4. First we look internally. If there isn’t an employee that fits the criteria for that particular position, we check our other stores that are close by. If all else fails, then we advertise employment. 5. Yes. Donatos wants every piece of diversity it can muster. We believe that different people bring different ideas that can help this company grow and be more successful. We do not discriminate against any race, background, or family history. Everyone has a fair chance to be a part of the Donatos family. 6. We would sit down with that employee, and try to understand his reasoning, if we can’t come to an agreement; he/she would be moved to either a different dept. of a new store entirely...

...thought triggered me to ask myself, “What would be my ideal summer vacation looks like?” To start my visualization, I would like to spend it in a place afar from the noisy streets of the city. A place where the only sounds I can hear are the chirping of the birds, the waves crashing on the shore and the laughter of my family. In that place, the trees are dancing gracefully and flowers are waving gently with the wind. In the distance, the shore is filled with sand so white, crystal clear water and with porpoises on the sea side. On the top of the hill resides our home, a small bungalow type but filled with so much contentment and joy. Inside of it are simple things to suffice our needs. Upon entering the entrance door, you will see the clean and tidy living room, with a window on the right that offers a beautiful sight of the blue ocean. Beside our home, there stood a tall and old narra tree that gives us shade during the day. Flowers of different kinds and varieties grows around the yard abundantly. Then, I can see the endless sky above with shiny shimmering stars blinking at night and in the water, it seems the unreachable stars are within my grasp. In a distance, I can see the fire keeps burning from the bonfire we have made, and beside it, sitting my loved ones with a happy face. Generally, my summer vacation would be an ideal one, even though I may not have those picturesque sceneries, what matters most will be the tranquility I have when I am with my...

...Wesfarmers Coal division, with mining interests throughout Australia, is part of Wesfarmers Limited, a major diversified Australian public company. They only produce thermal (steam) coal and metallurgical (coking) coal, with the latter being exported (Figure A). As shown in Figure B coking coal is priced much higher than thermal coal. The firm’s coal interests include the Curragh mine in Queensland’s Bowen Basin, the Premier Coal mine at Collie in Western Australia’s south west, and a 40 per cent interest in the Bengalla mine in the Hunter Valley of New South Wales. Before analysing the challenges, it is beneficial to examine the market Wesfarmers operates in. The marketplace for coal is domestic, with the majority exported on the global market. The coal industry can be described by the classic perfect competition model via the following characteristics (Earl & Wakeley, 2005: 226-227): • Large number of potential buyers (global market) • Large number of potential competitors. World Coal Institute estimates that recoverable coal reserves are in more than 70 countries and supply will last approximately 155 years (World Coal Institute: 2007). • Large number of current competitors. Each competitor sells a perfect substitute for Wesfarmers coal. • There is no price regulation in the coal industry. According to Earl and Wakeley (2005: 227), these characteristics would make Wesfarmers a price-taking firm which has no control of the price it charges for coal. It...

...Case Analysis Luotang Power Company Background Luotang Power Company is a 600 Mega Watt coal-fired power plant, located in Hubei Province, China, the parent company of which is China Hua Tong Power (HT Power). The major business is to generate electricity by coal burning and sell it to Hubei Provincial Power Company (HPPC), the major customer which is the only power transmission and distribution company in Hubei Province. Whereas the coal is purchased from Pindingshan Coal Company who is required to supply low sulfur bituminous coal that meets certain quality specifications. Regardless of the improved plant availability and fuel economy, the company wasn’t performing well for the financial result. A variances analysis indicated that the poor performance was due to a combination of shrinking revenue, increasing price of the coal and decreasing quality of the coal. Company analysis Macroeconomic analysis A PESTE framework including political, economic, social, technological and environmental factors is used to contextualize the company in an industry framework. Economic aspect: China is the world second largest energy consumer behind the United States. The energy consumption has been boosted by strong economic growth over the past two decades. Its electricity consumption is influenced by fluctuations in the GDP growth. (Appendix1) Hubei led the four provinces fed by the central China grid with a 13.8% rise in economy and is said to be doubled in the next five years...

...commercial whaling, convince world leaders to stop nuclear testing, and protect Antarctica ("Greenpeace", 2010). Through protest and working with universities that have on-campus coal plants Greenpeace is fighting for the future and the health of future generations by asking the universities to change policy and transition to 100 percent clean energy. According to the Greenpeace website Michigan State University burns over 2000,000 tons of coal per year. Students at Michigan State risked being arrested and staged a sit-in at the University President’s office to demand a meeting with her about their on-campus coal plant. The Present of the University never did agree to meet with the students. (Greenpeace, 2011). . According to "Green Peace" (2010) America’s coal burning power plants, in addition to causing global warming are killing Americans through poisoning our air and water and making our children sick. Over the next three years Greenpeace plan of joining local communities to shut down dangerous coal plants across the United States. They also plan on exposing climate deniers and hold them publicly accountable for providing millions of dollars to lobby against climate and clean energy policies. Greenpeace also wants to kick-start an Energy Revolution for clean-energy solutions like solar and wind power. According to "Green Peace" (2010) “In addition to advocating for solutions to global warming and climate change, we are doing...

...Abstract Global warming is a large increase in the Earth’s climatic temperature over a short period of time, and had become one of the most controversial topics that we have been facing. What impacts does global warming have on the atmosphere and what actions can we take to rectify the problem. Does global warming exist and what can we do about it? Global warming is caused by natural and human interference. Some global warming differences with natural and anthropogenic climates changes are, natural climate changes include volcanic activity and anthropogenic changes are caused by human influences such as burning coal oil. I believe that global warming is taking place; climate change has already had observable effects on the environment. Glaciers are shrinking, ice on rivers and lakes are breaking up earlier, plants and trees are flowering sooner. The changes in the weather is one indication, many places have been experiencing more floods, droughts and more severe heat waves. According to the Environmental Protection Agency (EPA), the average surface temperature across the contiguous 48 states has risen at an average rate of 0.13°F per decade. Average temperatures have risen more quickly since the late 1970s and seven of the top 10 warmest years on record for the United States have occurred since 1998, with 2012 being the warmest year on record. A second indicator is the change in the sea level. After a period of approximately 2,000 years of little change, sea level...

...luxury of power. As with most luxuries in life, electricity bears a cost. Yes, monthly we are billed for our household usage by the kilowatt, but there are other costs we’ve neglected to consider. Duke Energy, the largest electrical power holding company in the United States, plead guilty to nine violations of the Federal Clean Water Act in a hearing held this past May, which culminated in a fine of $102 million. The violations resulted from a spill of about 39,000 tons of coal ash due to a collapsed pipe under a coal ash dump that coated 70 miles of the Dan River near Eden, North Carolina with sludge. Coal ash is the inorganic residue left behind when pulverized coal is burned to produce electricity. Coal ash is one of the largest types of industrial waste generated in the United States and in 2012 the nation’s coal plants generated nearly 10 1milloin tons of it. A little less than half of coal ash produced in the United States is recycled into products like concrete, pavement or wallboard. However, the rest is stored, in over 2,000 storage sites across the country, in landfills, quarries or ponds that, over time, accumulates to potentially millions of tons of coal ash that contains some of the world’s deadliest toxic metals: arsenic, cadmium, chromium, lead, mercury and selenium. These contaminants can pollute, groundwater, drinking water and the air. All of these contaminants can be toxic and have the potential to injure all major organ systems, damage physical health and development...
