All rights reserved. 1 Abstract Clean and cost-effective power generation is of paramount importance to cope with the challenges imposed by an increasing energy demand throughout the world. Investment cost and fuel costs are the main contributors to the cost of electricity. In recent years, costs associated with CO2 emissions have attracted more and more attention due to its political awareness. The efficiency of the power plant as one key value affects both the fuel costs and the amount of CO2 emitted to the environment. As coal is more abundant in many parts of the world, coal prices are less volatile and more stable than natural gas prices. But larger CO2 emissions increase the need for more efficient coal-based power generation. Ultra supercritical (USC) steam power plants meet notably the requirements for high efficiencies to reduce both fuel costs and emissions as well as for a reliable supply of electric energy at low cost. Recent developments in steam turbine technology and high-temperature materials allowed for significant efficiency gains. Siemens has more than fifteen years of experience with ultra supercritical steam turbines and continues to optimize associated designs and technologies. This paper presents Siemens products and solutions for ultra supercritical steam power plants and their application in the 800 MW Trianel Power project...

...Introduction For this assignment about environmental injustice I have decided on the Cane Run Power Plant, also known as the operating site for Louisville Gas and Electric Company (LG&E), a coal-fired plant that is owned and operated by Louisville Gas and Electric in Louisville, Kentucky, located in Pleasure Ridge Park neighborhood. I will describe how the utility company LG&E is guilty of Environmental injustice to the Louisville residents of the Pleasure Ridge Park neighborhood, which Bell describes as powerless communities that suffer from human caused environmental disasters by the hands of powerful organizations and governments (Bell 2009). Case Summary Louisville Gas and Electric Company is a utility company that provides natural gas and electricity services for Louisville, Kentucky, which total to approx. 718,000 customers, as well the 16 surrounding counties (Unknown, Author 2014). LG&E provides these services from the Cane Run Power Plant located in the Pleasure Park Neighborhood, where the per capita income per household is approx. $21,831 per person (Unknown, Author 2013). This amount is considered considerably low. The power plant has been problematic for the residents of Pleasure Park for many years for a number of reasons, such as coal ash, which is a byproduct from burning coal, strong odors, and dust. Residents have reported burning nostrils and throat, abdominal pains, headaches, and sinus problems, eye and skin irritation, severe mental and physically...

...Fossil Fuel Dependency and Americans | SOC120 - Sociology | University of Phoenix | Lena M. Ward | 10/9/2011 | America’s primary sources of energy come from fossil fuels such as coal, oil, and natural gas. The cost of using fossil fuels includes labor cost to mine for coal or to drill for oil, labor and material cost to build plants to generate and transport coal and oil to plants; these hidden costs are included in electricity bills or in the purchase price of gasoline. However, some costs are not included in utility or gas bills, and they are not paid for by companies that produce or sell these energy sources (Payne, Dutzik, & Figdor, 2009). This external cost creates additional problems; such as, health issues related to the air pollution caused by the burning of coal and oil, the damage to land from coal mining and to the miners from lung disease, environmental problems like global warming, acid rain, and water pollution including national security cost to protect foreign sources of oil. This pricing system hides the true costs of fossil fuels which results in damage to human health, the environment, and the economy (Payne, Dutzik, & Figdor, 2009). This paper will examine each hidden cost and evaluate their effects to enlighten individuals on the true cost of America’s dependency on fossil fuels. America’s dependency on fossil fuels began innocently enough with the start of the Industrial Revolution. These changes were small at first with the invention...

...Scotia Power / Emera, Point Tupper, Nova Scotia Canada In 2004, B.I.D. was approached by Nova Scotia Power (NSP), to offer a project estimate for their new marine coal terminal. Since NSP's primary source of fuel (Cape Breton Coal Mine) was closed as of 2001, there was a need to diversify their fuel supply. The answer to this nagging business problem was to construct a new receiving terminal at the Point Tupper, Nova Scotia site, to import coal from various parts in the world, for their power generation. Our part was to design, manufacture, and install the custom system for their coal receiving, handling, and stock piling of imported coal. Since B.I.D. had supplied equipment for their similar project in Sydney, Nova Scotia, we were more than ready to deliver. However, prior to our part in this project came the site work- which consisted of rail work, rail modifications and environmental studies. The main contractor for this work, CBCL, was also a repeat client of ours. Both companies were confident in B.I.D.'s reputation to solve a problem. Environmental, economical, location and port considerations accounted for several revision requests to the system- no problem for B.I.D. The complete material handling system was built to receive coal and petroleum coke from self-unloading ships and from an E-crane unloading bulker ships- which were to then transport the product on shore to two storage piles at a continuous rate up to 3000 TPH using 54" wide belts. Components...

...The Future of Energy: Rooftop Solar Panels Coal fired energy plants have long been recognized as extremely damaging to the environment. The role of carbon dioxide, a greenhouse gas, in precipitating climate change is well documented. Carbon-dioxide emissions have increased manifold since the Industrial Revolution and have led to an increase in the Earth’s temperature in the past 50 years, worsening forest fires, drought and coastal flooding among other disastrous side effects of climate change, according to the U.S. Global Change Research Program. (NOAA National Climatic Data Center). In Kentucky where 91% of its power is generated from coal (Department for Energy Development and Independence; Kentucky Coal Association), there is a great impetus for utilities to cut down on carbon emissions. Unfortunately current efforts to reduce carbon emissions are largely insufficient because they do not attempt to reduce America’s and Kentucky’s overreliance on fossil fuels such as coal and natural gas. Rather, currently adopted technologies like carbon capture and storage (CCS) and natural gas-fired plants that halve carbon emissions merely seek to reduce the environmental impact while still relying on fossil fuels for energy. (Nijhuis) (Breeze) For a solution to be viable in the long run, it must propose an alternative energy source to reduce our reliance on fossil fuels for energy which is the root cause of excessive carbon emissions. Investing in renewable energy like solar power is...

...Nuclear energy regarded as a source of power. Also called atomic energy Nuclear power was first known to be researched in the early 1900's, and by the world war; it reached its greatest peak by demonstrating to the world its power to destroy. Nuclear energy can be good or bad, depending on how the person works with this material; it is used for both sides good and bad. Scientists were unsure from the beginning of how it was possible to get energy from the material called Uranium. They were sure that with its uniqueness it would be able to transform itself into different elements. So they were unsure of it for many years, until Albert Einstein he explored the world of nuclear energy. In 1905 he released his theory of the famous equation e=mc2 with this he knew that uranium was able to create masses of electricity. A few years later, scientists found out the great power of the atomic energy. Since then, both scientist and the public were unable to find the best fit for nuclear energy in our society. We have put it into power plants, but the government and public were disappointed by accidents. We have put it into war, and with it we have caused great damages. So the question is where can this energy go? Even though it has been discovered to be the greatest power source of the world today, nobody is willing to cooperate with it because of these accidents and accomplishments. I am not sure if my findings are accurate but by source tells me that today there are a total of...

...Burning fossil fuels such as oil and coal are changing the climate and making thousands of Americans sick. Coal burning power plants are poisoning the air and water. “Fossil fuels account for more than 80% of US global warming” (Jon Van, 1988). Burning fossil fuels releases carbon dioxide in the air, creating a greenhouse effect that traps heat in the atmosphere making the Earth heat up. “Each year, an average of 24,000 Americans die as a result of pollution from coal burning power plants” (Greepeace, 2010). Mercury and other toxic compounds are being released into the air and eater. Acid rain caused mostly by coal burning costs $10 billion a year in crop damages (Jon Van, 1988). Oil is the most used form of energy and accounts for 38% of the global energy source. 30% of carbon dioxide emissions in the air is caused by oil burning (MSc, 2003). Oil spills such as the BP Deep water Horizon leaked thousands of gallons of crude oil in the sea, contaminating water, beaches, wetlands, and destroying sea life. BP was burning oil from the surface, which released poisonous gasses into the air causing people to get sick. Sea life has also been heavily impacted and the full effects of the damage to the eco-system will not be known for years. People have an obligation to find and use alternative energy sources. We need to stop putting people, animals, and the environment in danger. With the continued use of coal and oil, we are heating up our plant, depleting and destroying our land...

...utilized. There is coal, which is a nonrenewable energy resource because there is a limited amount of supply. Then there is wind and hydropower, which are considered renewable energy resources; because there is an infinite amount of supply. The city council may want to take into consideration these two renewable energy sources for the many different advantages each source has to offer. West Virginia has an abundance of natural energy resources such as coal, wind, and hydropower; all of these energy resources could generate electricity and stabilize the community’s economy in various ways, including the different types of facilities, cost, and production output. West Virginia coalmines are amongst the top in the country for coal production. A 2009 study showed that five states in America produced close to three quarters of all the coal in the entire country, and West Virginia was number two on the list. Coal is used to generate electricity, heat, and for industrial uses. In the 2009 study, over ninety percent of the coal was used to generate electricity, a little over six percent was used in the industry, and less than one percent was used to generate heat (“Coal” 18). West Virginia mines a large portion of the countries coal every year and in order to keep up the high demand, most of the state workforce is employed by the coalmines. The West Virginia coalmines are the economic backbone for the state. There are a couple of key elements that make the coal mines so prosperous...

...Reproduced with permission from Energy for Sustainable Development Articles Synthetic fuel production by indirect coal liquefaction Eric D. Larson Princeton Environmental Institute, Princeton University Guyot Hall, Washington Road, Princeton, NJ 08544-1003, USA E-mail: elarson@princeton.edu Ren Tingjin Department of Thermal Engineering, Tsinghua University, 100084 Beijing, China This paper reports detailed process designs and cost assessments for production of clean liquid fuels (methanol and dimethyl ether) by indirect coal liquefaction (ICL). Gasification of coal produces a synthesis gas that can be converted to liquid fuel by synthesis over appropriate catalysts. Recycling of unconverted synthesis gas back to the synthesis reactor enables a larger fraction of the coal energy to be converted to liquid fuel. Passing synthesis gas once over the synthesis catalyst, with unconverted synthesis gas used to generate electricity in a gas turbine combined cycle, leads to less liquid fuel production, but provides for a significant second revenue stream from sale of electricity. Recently-developed liquid-phase synthesis reactors are especially attractive for ‘‘oncethrough’’ processing. Both ‘‘recycle’’ and ‘‘once-through’’ plant configurations are evaluated in this paper. Because synthesis catalysts are poisoned by sulfur, essentially all sulfur must be removed upstream. Upstream removal of CO2 from the synthesis gas is also desirable to maximize synthesis productivity, and it provides...
