The Pros and Cons of Different Energy Sources free essay sample

They are an important source of energy that we have come to rely on, however, these days there many discussions have been taking place concerning their usage and the impact they play on the environment. As such, I will now list the pros and cons of fossil fuels. The pros of fossil fuels are as follows: 1) One of the advantages of fossil fuels is their existence as high efficiency sources of energy. The reason for this is that, when consumed they produce large amounts of usable energy. 2) Another one of the advantages of fossil fuels is their availability. Fossil fuels are not difficult to obtain from the earth. Also, due to the fact that the extraction and refining processes don’t take long, the fuels are able to be converted from their crude form into forms that could be used for a number of different purposes (Buzzle. com, 2013). 3) The third advantage that fossil fuels have is the ease at which they can be transported. We will write a custom essay sample on The Pros and Cons of Different Energy Sources or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Fossil fuels like coal are able to be transported by train, while oil and natural gas are transported by pipelines. This ease of transportation enables the places that convert these fossil fuels into usable forms, to not have to worry much about location (Buzzle. com, 2013). 4) And lastly, fossil fuels are not only used for energy, but also to create byproducts such as plastic that are used in almost everything (Locsin, n. d. ). Now, the cons of fossil fuels are as follows: 1) One of the major cons of fossil fuels is the danger they pose to the atmosphere. The burning of fossil fuels causes the release of large amounts of carbon dioxide into the atmosphere. This is bad because carbon dioxide is one of the greenhouse gases that contribute to global warming. And that is not all, another one of the gases that is released when burning fossil fuels is sulfur dioxide. This toxic gas produces acid rain when it interacts with the atmosphere. 2) Another one of the cons of fossil fuels is the damage that is done to the landscape when collecting it. An example of this can be seen in coal mining. The landscape where coal is mined is damaged to the point where it is not able to be used for anything else. ) And last but not least, fossil fuels are a non-renewable source. And right now they are being used at an alarming pace because of how modernized our society is these days. So it might not be too far off in the future, when a time will come where we won’t be able to obtain anymore fossil fuels (Buzzle. com, 2013). What are the pros and cons of nuclear energy? The pros of nuclear energy are as follows: 1) One of the pros that nuclear energy b rings is a reduction in the amount of greenhouse gases released into the atmosphere. 2) The second advantage is their relatively low operating costs. ) And lastly, nuclear energy has a large power generating capabilities, that allow for it to be used for industrial and city aspects (Buzz, 2009). The cons of nuclear energy are as follows: 1) The cost of constructing a nuclear energy power plant is high. And that is due to the equipment that is needed to contain the radiation. 2) One of the major concerns of nuclear energy is the disaster that could follow in the event of an accident. 3) And last but not least, another con that really is troublesome is the trouble of disposing of the waste. For one, the waste can last for a couple hundred years. Also, there is the ever present danger that it could leak out and contaminate ground water sources in the area (Buzz, 2009). What are the pros and cons of solar energy? The pros of solar energy are as follows: 1) Solar energy is renewable source of energy. As long as the sun is shining, solar energy is able to be produced. 2) The second advantage is that it is a clean source of energy. 3) And lastly, solar energy is a free source of energy, and its solar panels require almost no maintenance (Energy for Mankind. org, 2011). The cons of solar energy are as follows: 1) Solar energy can only produce its maximum of energy during the day, and when the sun is shining the longest. 2) Solar panels are very expensive. 3) And lastly, a lot of space is needed in order so the exact amount of solar panels that are needed could be installed (Energy for Mankind. org, 2011). What are the pros and cons of wind power? The pros of wind power are as follows: 1) It is a renewable source of energy. 2) It is also clean and free source of energy. 3) It won’t take long to recover the cost of purchasing and installing the wind turbine. ) And finally, a cool advantage of wind power is the fact that the electric company will reward for any excess energy that you produce but don’t use (Bernard, n. d. ). The cons of wind power are as follows: 1) One of the cons of wind power is its inconsistency. Since wind does not blow continually, wind turbines usually operate at 30% of their capacity. 2) Wind turbines have expensiv e upfront costs. 3) And lastly, another con of wind power is location. A wind turbine requires a lot of open land, in order to operate properly (Bernard, n. d. . What are the pros and cons of water (hydro) power? The pros of hydro energy are as follows: 1) Hydro power is a clean, renewable source of energy. 2) With the construction of a dam, there will be an abundance of electricity produced for many years. The cons of hydro power are as follows: 1) One of the cons of hydro power is the cost of constructing the dam. 2) The dams have to be built to the highest of standards. Precision, accuracy, and the right materials need to be utilized in order to achieve that goal (Energy for Mankind. org, 2011). What are the pros and cons of biofuels? The pros of biofuels are as follows: 1) Biofuels produce less carbon dioxide and other greenhouse gases than a fossil fuel like oil. 2) Another advantage of biofuels is that they are immediately useable. 3) And lastly, Biofuels are high quality fuels that have allowed us to reduce our dependence on fossil fuels (Biofuel sustainability pros amp; cons, 2006). The cons of biofuels are as follows: 1) One of the cons of biofuels, is an increase in the clearing of rainforests in developing countries, in order to grow biofuel crops like corn. ) The growth of biofuel crops can have a negative impact on the prices and security of food. 3) And lastly, the creation of biofuels burns more energy than what is contained in the finished product. Therefore it isn’t an efficient fuel (Cunningham, n. d. ). When it comes to the Energy Policy Act of 2005, two of its provisions that I found interesting are the daylight savings time extension, and the creatio n of the energy star program. In the provision concerning daylight savings time; the daylight savings time was extended two weeks in the spring, and one week in the fall. These changes were to take place in the month of August of 2006. On the other hand, in the provision about the creation of the Energy Star program, the government created the program under the DOE and Environmental Protection Agency. The symbol of the Energy Star serves as an indicator of energy-efficient products and buildings. Last but not least, some of the tax incentives included in the Energy Policy Act of 2005, were for the installation of energy efficient appliances, residential energy properties, new homes, commercial buildings and more (Think Energy Management, LLC. n. d. ).

Run For the Border Comparison of the Mexican and French Revolutions essays

Run For the Border Comparison of the Mexican and French Revolutions essays ""It is easier to run a revolution than a government" (Ferdinand E. Marcos (1917-81), Filipino politician, president. Time (New York, 6 June 1977). ) Websters dictionary defines the word revolution as an overthrowing of government [and/or] radical change (Websters). The usual goal of a revolution is to change something that the populace does not like. The Mexican Revolution of 1910 was just that. The changes made in the Mexican government during the first half of the twentieth century bear many resemblances to changes made during the French Revolution. According to Brinton, there are four stages to every revolution. The preliminary stage was when both Mexico and France set up the problems to come in the future due to the leadership at that time. The preliminary stage then led up to the first stage where frequent uprisings occurred against the government and sometimes even the people. The third and perhaps most turbulent of the four stages was the crisis stage, where some streets ran red with blood, and order ran amuck. The final stage is the recovery stage, where the governments agreed upon a plan that would benefit the p eople who worked so hard for the changes to see the fruits of their labor. The preliminary stage of the Mexican Revolution was much like that of the French Revolution. President Porifirio Diaz was a prosperous President of Mexico for thirty-one years and ran the country much like Louis XVI of France. Diaz gave most of the power to a select few, while the majority of the country did not have the right to vote for the officials they wanted or to express their own opinions, limitations that are similar to the third estate of the Ancien Regime. With such conditions, wealth was likewise concentrated in the hands of the few, and injustice was everywhere, in the cities and the countryside alike (MexConnect). With these similarities however, there came many differences. ...

Print and TV Media Essay Example | Topics and Well Written Essays - 750 words

Print and TV Media - Essay Example Television, or TV, literally means the unit that is used to receive broadcast signals from a network, and, in this case, refers to the actual use of TV-a means to get information on a regular basis. Shows on TV also vary in frequency, usually within minutes, hours, days, and weeks. Take a regular newspaper, roll it, tuck it under your arm or toss it in your bag, and you can read it whenever you've got the time-unless you want to get the information right here, right now. Such is the essence of the newspaper; news and information delivered through the convenience of compiles sheets of paper that one can carry around, as well as the corresponding affordability. On top of that, the availability of space in its environment allows print journalists to write lengthy news and feature articles, giving the reader access to more information that can be referred to anytime. The downside of it is the amount of time spent producing a single issue-a process that produces hundreds and thousands of copies-and how it measures against other sources. In this day and age, where everything can be accessed in one click, the speed afforded by print media is no longer up to par with the rest. This is particularly true for news-based publications, because this obstacle relegates them, by default, to last place in terms of relevance. On the other hand, if relevance is the is... A news anchor can be on air in seconds, and can announce breaking news even from remote locations via satellite right where and when it happens. Best of all, TV is visual-all the better to narrate in 30 seconds what a newspaper story will do with only words to rely on. Most people are inclined to TV than print, precisely because of this attribute. But TV can only be TV, at least for the mass market, if one has an actual TV. Compared to the print production process, the broadcasting system is far more complicated, requires more people to run it, and necessitates equipment that can never be called cheap. Plus, unlike newspapers, one can never read back what has been reported-unless a replay is run. III. Content is King, Distribution is Queen What a reader or viewer gets from both TV and print is almost identical. The reason for this lies in the preferences of its targets-the regular reader and the frequent viewer-whose loyalty the two media are always after. This resulted in the creation, development, and innovation of the material each features, known as content. News articles and breaking news. Coming from the same source, using the same methodology, but using different executions, these two form-specific materials naturally provides for the same need-that of knowing what is happening of significance at the moment. Magazines and variety shows. These two forms are actually several parts joined together to produce a printed material, or an hour-long show. They aim to cover certain interests, and, with the objective of making things fresh and upbeat, rely on the novelty of each section or segment. Dear Abby letters and drama programs. Many people are fond of emotional revelations,

British Colonization Essay Example | Topics and Well Written Essays - 750 words

British Colonization - Essay Example In the 17th century United Kingdom the term "colonization" came to be utilized in a polemical manner to distinguish the domestic and local programs of the British explorer Captain John Smith. The major mistake or failure of the British colonizers, in an ancient tradition to identify themselves from the European continent, is that they did not classify their own programs to be as dominant as what people thinks. They did mention of "colonization", the transfer of individuals from the European continent to other regions of the world, paving the way to a â€Å"larger Kingdom† of English population. Majority of the British's colonies also failed to find benefits in organized, domestic colonization: great economic and industrial cartel desired for colonizing aid to secure their domestic assts against rivalry and international political conflicts overseas; bureaucrats desired and searched for government positions; people in the security wished for higher responsibilities and ranks; and the usual but striving desired for improved income for their businesses, ranks, and public office responsibilities. A distinctive success of the British colonization was the fact that it caused the emergence of fresh social perspectives of domination. Viewing the emergence of business unification, socialism, and other propaganda on the outset of a period of mass community in both the United Kingdom and later in the Western nations, the British colonizers strived to utilize imperial concepts to coordinate the aid of part of the economic working group. The re-energized mass media advocated colonization in various global wars that happened during the late 19th century and early 20th century. In the 15th century the "colonization" efforts of the British people also emerged to be connected to any ancient or traditional example of a larger authority initiating, or being viewed to be initiating a move, at the expense of a lower authority. The success of the British colonizers was therefore not only utilized to pertain to merciless territory-building programs, which include those of the Italians, the Spaniards or the English powers, but was also utilized uncharacteristically and/or disparagingly, for instance by both sides in communist and anti-communist movement, or to pertain to initiatives of the United Kingdom since the British government's takeover of outside borders on the onset of their feud with Spain, or in connection to the America's current position as the globe's most powerful country. 2. What were the similarities and differences between Spanish and British colonizatio

Brain Mechanism And Artificial Intelligence Psychology Essay

Brain Mechanism And Artificial Intelligence Psychology Essay Artificial Intelligence is the art of programming computers in order to produce intelligent behavior, whereas brain theory is the study of the brains function, to understand how the brain functions, the stimulations that go within and how outputs are produced via mathematical modeling and computer stimulation. It can be argued that both contain similar characteristics for functionality, both works together, this can be seen through artificial intelligence used to understand the roles of brain mechanisms. Furthermore both are involved in high cognitive task, such as reasoning, problem solving and decision making. Although some philosophers have accepted that machines can do everything that humans can do, some disagree with this view arguing that such high sophisticated behavior such as love, emotions discovery and moral decisions can only be carried out by humans. AI for many years has been pursuing the study of intelligent behaviour, but using artificial methodology. Intelligence can be defined as the ability to learn and understand, to solve problems and make decisions, both AI and the human brain share this characteristic. In order to study human intelligence some use artificial intelligence to understand human processes. One of the most significant papers on machine intelligence has been explored by Alan Turning; however his theories still remain universal. Turning (1950) predicted that by 2000, a computer could be programmed to have a conversation with a human interrogator for five minutes and that it would be able to deceive the interrogator that it is human, this suggest a link between AI and brain mechanisms. Both the human brain and machines are able to solve complex mathematical calculations; a machine may be designed to solve these calculations faster than the human brain. Although evidence suggests that our brain stores the equival ent of about of over 1018 bits and can process information at the equivalent of about 1015 bits per second. Therefore both AI and brain mechanisms can work together to produce efficient results, as it is evident that both accept input and generate the correct output. It is required that an intelligent machine should help human make decisions, to search for information, to control complex objects, and finally to understand the meaning of words. One of the possible definitions of AI refers to cognitive processes and especially to reasoning. Before making any decisions, people also reason, it is therefore natural to explore the links between both. Since the early 1950s, there has been a vast development of AI where it has become a valuable tool to support humans making decisions, similarly specific brain mechanisms are involved in decision making in the brain, one can argue that both working together will lead to more valid and faster decisions. To support this, research shows that more sophisticated and user-friendly forms of computer-assisted decision aiding technologies are being developed, examples include decision support systems and external information retrieval system, this then can work alongside brain mechanisms. AI has largely been used for problem solving; such machines have been created than can go beyond the human brain ability to solve problems. These include solving mathematical problems of high complexity; these are programmed to do exactly what we want them to do. AI is now involved in solving real life issues, which are usually dealt by human brain mechanisms, some may suggest that it may reach to such an extent that it outperforms the best traders and investors. Evidence suggest that they are already involved in to forecast the economy and analyze credit risk, these just being to examples. This is a rapid growing field which needs to be given attention. More money is being spent on this as the developments in this field have been immense. Neural networks, is one specific type of AI that mimics many characteristics of the human brain. Research suggests that neural networks are able to draw conclusions of data that is incomplete and may learn from previous mistakes, thus imitating per formance outputs by brain mechanisms. AI systems are increasingly being developed and increasing rapidly, this is because of the variety of applications it includes, such as symbolic reasoning, flexibility and explanation capabilities, thus both AI and brain mechanisms can work together and produce efficient results that would make every day life seem less effortless and produce faster results. The goal of building AI agents was that it provides efficiency and most importantly works parallel to brain mechanisms, such as contains features such as cognitive abilities which will play a role in decision making and help in difficult and complex human situations. Furthermore cognitive abilities such as perception, reasoning, learning and planning turn technical systems into systems that know what they are doing; therefore they may function in parallel to the ways brain mechanisms do. Through the years there has been vast developments and more work is being put into these systems in order to it contains certain amount of repres ented knowledge , learn from previous experiences in order to prevent mistakes previously made and so that it makes further improvement and changes. Furthermore developers have aimed to develop AI even further, such as justify the actions and decisions made, be aware of the capabilities it contains and be able to reflect on its behaviour, these are the same roles that brain mechanisms play, thus they aim to create a parallel model. Although such developments have been made through many years, it may be argued that AI may still not be able to compete with the advanced functionality of brain mechanisms. Despite the speed and memory capacity, AI struggles to contend. The human brain contains around 20 billion neurons, each neuron being connected through synapses of approximately 10,000 other neurons, which AI cannot possibly mimic. However there has been continuous progress and advances of AI, an example might be face recognition software, which detects photos; the brain does this automatically, and relies on memory similar to AI where it uses its stored memory for collection. In AI this has been used for security purposes, which have demonstrated to be very successful. Previous advances include voice recognition, which both AI and brain mechanisms share. For AI this has not only be used in terms of security reasons but also in order to function the device and making it more easier and convenient for use, this has been done through using different applications, where it involves programming, the same way the brain mechanisms programme in order to carry out specified roles. In addition although AI applications use many techniques, the fundamental building block is called the neural network, likewise brain mechanisms functions the same way. Things that were difficult to reason earlier on have become easier to understand through advances in technology. As the human brain being such a complex mechanism it has been difficult to observe human brain activity. New advances have been made in recent years, FMRI (Functional Magnetic Resonance Imaging) being one of these discoveries which has helped immensely to capture brain activity, this has been significant help for AI as it enables to have an insight on brain activity, which may help advance and help imitate brain mechanisms. Furthermore, this then shifts the balance between building artificial intelligent systems and studying natural intelligence. It should be expected that in the future, there should be numerous studies on relating artificial intelligence to natural intelligence. Current evidence suggests that both can work together to demonstrate different cognitive states in humans, here artificial intelligence has been used for learning algorithms to distinguish between various cognitive states observed through FMRI. Looking at this area further, natural and artificial intelligence are both said to be closely related in most objects and in everyday life generally. Both get impacted if are hit physically. Human behavior is said to be artificial at times, both function through language and communication. Communication is essential for both AI and brain mechanisms in order to function. Through communication they are able to send out essential messages, which helps to maintain these systems and allows them to function effectively and plays a key role in all aspects. AI shares many characteristics with brain mechanisms; one may argue that an essential feature which only human mechanisms can produce is emotions. Emotion is defined as a persons feelings and behavior which has a direct affect on the performance, emotions may act as an obstacle to produce intelligent outcome, thus it can be argued that because AI lacks to produce emotions this may not have an impact, therefore not having an influence on the outcomes it produces. However it is essential, that in order to emulate human behavior and to work alongside humans that AI should have emotions, it is required that not only should it think and reason but also be able to show emotions. Overall evidence suggests that both artificial intelligence and brain mechanisms are closely related, both work together in order to produce efficient outcomes. AI and brain mechanisms share many key characteristics such as reasoning, problem solving and decision making and intelligence. Recent evidence suggest that AI has allowed us to understand complex brain processes, this then enables to understand human actions and decisions in more depth. However many researchers still argue that the high level cognition can only be produced by brain mechanisms, such as emotions and feelings that AI fails to produce.

Drinking Alcohol Makes Women More Beautiful :: Research Essays

Drinking Alcohol Makes Women More Beautiful While driving around in my friend’s car my other friend, Michael, commented on how he was going to get plastered, and find some girl to hook up with and he didn’t care about anything else just as long as she had a "nice personality". Others chimed in to the same affect and this got me thinking is this what people really think about when drinking? Is only one thing on their mind? My answer to this question is yes. That is why I chose to do my research paper on this topic. Going into this I decided on a hypothesis that is after a certain number of alcoholic drinks people find others more attractive. This in turn leads them to do other things that normally they would never dream of doing, but it doesn’t really matter, because they have the drunk factor to fall back on. Through a survey, interviews and a case study I have found my hypothesis to be more than just a theory. I will begin with my survey finding. I conducted a survey of 10 people, both males and females, consisting of 10 questions. Now I figured this would happen, but it was the opposite of what I thought they would answer. All of the questions were non-bias and helped me to get a better understanding of the relationship between attractiveness and alcohol. Let’s begin with my survey findings. Among some of the questions I asked were how many times a week do you drink, does your confidence go up after consuming alcohol, do you think alcohol affect others attractiveness to you, and who do you think males or females are more likely to be affected by "beer goggles". A surprising 80% said they drank more than 3 times a week. 20% of males said they had more confidence after drinking, where as 40% of females said they did. I assumed everyone would answer peoples’ attractiveness is affected by alcohol, but the votes were split 50-50. And 90% of those surveyed said that "beer goggles" affect males rather than females. I also interviewed a guy and a girl that had differing opinions about the questions. Some of the answers I got surprised me from both the male and female. My first interview was conducted in the cafeteria, with a 19-year-old sophomore female. The other was in Stouffer and with a 20-year-old junior male.
