Renewable Energy As A Replacement For Their Energy Needs

Powering Tomorrow Most American families are dependent on fossil fuels for their energy needs. However, the cost associated with fossil fuels is very unstable and has caused many to seek alternative sources. Countless experts think, that alternate source has been realized in the form of renewable energy. These types of energy have shown potential for sustained demands, economic growth, and environmental benefits. Consumers should consider renewable energy as a replacement for their everyday energy needs as they are a better and more beneficial source of power. Currently, fossil fuels provide the majority of our nation’s energy demands. Some studies suggest that the dependency rate is calculated at approximately 80% to 85% (Kalb). There are a lot of factors that contribute to this high rate of reliance on fossil fuels. Nonetheless, this rate places the United States at the mercy of foreign oil producer’s. Moreover, it is not helpful that some of these oil producing countries are unstable or are at odds with the United States’ foreign policy. Therefore, prices for fossil fuels tend to fluctuate regularly. Though, over the past two decades, science and technology have been working in concert to hone the potential use of the earths replenishing energy sources. These advancements have led to a slight surge in the growth of renewable energy.

Edgar Allen Poe is very well known for several profound short stories. The Tell Tale heart is known around the world. The story The Tell Tale Heart, by Edgar Allen Poe Shows the reader the inner complexity behind the unnamed, main character who in this particular story is also the narrator for the reader. Poe portrays a character whose almost every sensory that is used in the story becomes a reminder of the crime he has committed. The conflict within the narrator is extremely noticeable in the beginning of this story. Due to obvious clues and statements, Poe indicates that the Narrators metal state is indeed insanity. The insanity begins to worsen because the narrator’s obsession with the old man’s eye which causes him to lose†¦show more content†¦However in his mind the old man’s eyes begin to create illusions such madness that any sanity or compassion he/she once had is now gone and in its place is obsession and insanity. Point of View: Since Poe, mainly uses the narrator as a source of first person point of view that allows the reader to more interested and captures there attention almost endlessly. The first person point of view us what makes the Tell Tale Heart so compelling and chilling. At one begins to read the story right away at the beginning the narrators emphasis that he is not â€Å"mad† but instead he is completely sane. However as the readers continues with this chilling story they realize that the more the narrators tries to claim his sanity the more convince one becomes that he is indeed very â€Å"mad†. Also with the conclusion that the narrator is not at all sane, one becomes aware that they are dealing with an unreliable narrator creating more complexity and intensity. Therefore the demented views of this narrator allows the audience a disturbing look into the mind of a seriously callous person, and that adds to the authors overall haunting tone. By using first perso n point of view, this enables the reader to see how the narrator feels as the story is being told, as well as help contribute to feeling that are being created in the readers mind.

Internet Technologies for Creativity and Innovation - myassignmenthelp

Question: Discuss about theInternet Technologies for Creativity and Innovation. Answer: Introduction The internet as we know is going to change; today its a massive network that allows people to communicate with each other. With the implementation of the technique emails, sharing data with it the use various websites, it is the people that really drive the internet today (Cui, 2016). The data which is send comes from various devices such as Personal Computers, laptops mobiles then it goes to some servers and then the servers sends it further for processing. Thus we can say the internet is made of three major actors the people, the cloud devices and the servers. A whole new category of actor is being added to the internet which can be called as internet of things; hence the term internet of things can be a future goal in many working areas. It can be stated that the internet of thing is basically anything that has a sensor attached to it which can transfer the data further up into the internet that can be analyzed or used to make decisions. Examples of such sensors are temperature se nsor, usage monitor etc. these things then further send that data to a person or a piece of software to make these decisions. Smart phones, social media all changed the way that we do things both in a personal level in a business level (Benardos Vosniakos, 2017). Internet of Things (IoT) The internet of thing is mainly considered as a system of interrelated devices of computer, digital machine and mechanical which are provided with identifier which are unique and has the ability to transfer the data over a network (Mulani Pingle, 2016). This technique is done without any human interference or computer human interaction. The internet of things evolved from the wireless convergence concept of technology, micro service and system which are related to internet (Cui, 2016). The wall between the information technology and operational technology was broken with the convergence of the technology. Practical implementation of the technology can be found everywhere and in many sectors of industry. The example of industry where internet of things can be implemented are building management, health care industry and transportation sector (Osseiran et al., 2017) All devices in the internet of things must communicate with each other in order to provide a good communication and working of the technology (Dong et al., 2016) within the application of industry, sensors on the product can increase efficiency and as a result of which the waste production would be reduced highly. If the internet of things and its concepts can be implemented in a proper way it could lead to a serious impact in many fields (Li Da Xu, 2017). Improved application or implementation are making their approach in the real world and it can be estimated that internet of thing with the new technology would play a vital role in the near future. Example of an Internet of Things device The Omega 2 - it is the worlds simplest tiniest development board which can easily fit into any project. The omega 2 is a flaxen computer which powers some of the most mission critical infrastructure (Mulani Pingle, 2016). The omega 2 works out of the box which comes with built-in wifi and onboard storage which comes to life the moment you power it on. The omega 2 is easy to program. its supports many programming languages such as python, PHP, C++ and many more just pick one and start building (Osseiran et al., 2016) The omega 2 is cloud connected which means u can remote control it from anywhere in the world using any smart device. Benefits of OMEGA 2 It does not just benefits one but everyone such as business, society etc because it saves time and money. It is uses in home security devices are uses in homes to monitor their houses on a timely basis from anywhere in the world. OMEGA 2 used in lighting systems (automated turnoff lights) can save money on your electricity bill. Now a days we all want out devices to be connected to each other using OMEGA 2 us stay connected to these things so that we can keep a track on what we are doing , listening, reading etc as we move from place to place (Bughin Chui, 2017). Drawbacks of OMEGA 2 As all of the appliances, public sector services industrial machinery are connected to a network, it can be hacked by professional hackers making them vulnerable. Different devices of different manufactures are going to connect there will be a compatibility issue which can be solved if all just agree to one common standard. Any failure or bugs in the software will result in crashing the whole system (Osseiran et al., 2016). Unskilled workers will lose their jobs due to automation resulting in unemployment problems. Advantage of internet of things Ubiquitous network: Connection of the wifi is easy. Connected computing: Keeping track of what is going on with any aspect involved in it Ubiquitous sensor: It can be implemented everywhere because internet of things is also wearable revolution(Benardos Vosniakos, 2017). Analytics as a Service: Anything can be done which drives the attention of the user. Intelligence at the periphery of the network: every disk and each sensor will be a competent (Bui, 2016). Conclusion It can be concluded from the report that its a market with a lot of potential development, using these types of products helps save a lot of time and money. Although it has its disadvantages but we should not overlook the fact that its going to chance the environment around us as we know it and efforts will be implemented to combat those disadvantages. Internet of things may set new platforms in the distant future. Internet of things will result in the growth of economy so progressive companies like Intel Samsung are trying to capture this market. It is estimated that by 2020, 26 billion devices will be connected to it. References Benardos, P. G., Vosniakos, G. C. (2017). Internet of things and industrial applications for precision machining.

As the Sun Rose free essay sample

As the Sun rose its hour began to awaken the every pulsating wonders of everything in its path. I found myself in an unsettling state of mind with thoughts of what troubles and worries this new day would bring. As I sat there in the car with my cup of French vanilla because coffee was too bitter for me, I watched my sister’s every step to the door. My French vanilla scent took my mind off everything, as I continued to search for something set my gaze upon. It was still dark, with a very cold and damp touch from the night’s rain. The air had a dew feel to it, and the traditional smell of rain on dirt. I finally fixed my gaze on the horizon, the clouds began moving and forming a slightly distorted version of the daily morning sun rise. The rain had somehow altered the clouds, because the sky was crowded and it seemed as if the sun would not get to shine through like it did so many mornings before.

The endings and beginnings of these colors could not be discovered no matter how long or hard I stared. I watched as the invisible artist ran its brush side to side, up and down changing its painting every second. The air began warming and the birds chirped as if they had an unknown secret. It was the strangest thing even though the sky was being blocked the darkness from the night began to lighten and soon vanished until everything was able to be seen. Of course the day was gray rather than its normal bright sunny day, but still the shade was remarkable. The sun could be spotted if sufficiently focused on. But by this time five sixths of the sun was in the sky. A minute later, fine traces of yellow broke the bonds of the clouds. The scent of the rain on dirt grew stronger and so did the dewiness. Puddles then showed of the nights shower, everything was covered by splashes of wet droplets. Once the sun regained its day position, the clouds had surrendered its grip and soon openings revealed the bright blue sky and all its passion of sun light.

Overpopulation Essays (1281 words) - Demography, Population

Overpopulation "The battle to feed all of humanity is over. In the 1970's the world will undergo famines-hundreds of millions of people are going to starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate, although many lives could be saved through dramatic programs to "stretch?the carrying capacity of the earth by increasing food production. But these programs will only provide a stay of execution unless they are accompanied by determined and successful efforts at population control.? These words, from Dr. Paul R. Ehrlich's book The Population Bomb, predicted a grim future for the world of 1968 when the book was published. Today, the debate rages on about how much life our planet can hold. With world population estimates currently around 5.5 billion, and a projected population of over 10 billion by 2100, the question of resource scarcity is raised. Will there be enough resources to support the exploding population of our planet? Also, is it true that population growth is necessary for economic prosperity, or is it responsible for problems such as hunger and poverty? One of the first things that need to be considered in the population debate is the issue of "carrying capacity.? Many different people define carrying capacity in many different ways, and in this lies a major problem. Basic ecology textbooks define carrying capacity as the number of individuals in a population that the resources of a particular habitat can support. Others define it as the point at which the birth rate is equal to the death rate, while still others define is as the average size of a population that is neither increasing or decreasing. Each different definition of carrying capacity has different arguments for the earth being above or below its carrying capacity, or of having infinite carrying capacity. Also, many other factors must be considered when estimating the earth's capacity by any of the above definitions. For instance, one must consider the level of prosperity of the people, the technology available, and the distribution of available wealth. Under certain conditions, the world might not easily hold even 1 billion people, while under other conditions a number as high as 20 billion is possible. Another factor in overpopulation that must be considered is that of life expectancy. According to United Nations estimates, the life expectancy in developed nations in the 1950's was approximately 66.0 years, while third world nations enjoyed a life expectancy of 40.7 years. Due to substantial declines in infant mortality, the average life expectancy in developed nations was 74.0 years and 64.7 years in developing countries. However, although the majority of this increase is due to decreases in infant mortality, jumps with this large of an increase cannot be entirely explained by that alone. New developments in medicine and technology have increased life spans across the board. Even more promising, and perhaps alarming, is the fact that predicted "upper limits?of human life expectancy have regularly been surpassed, and increases in life expectancy even appear to be accelerating. These average life expectancy increases, if they continue, will allow the world population to skyrocket at an even faster rate. Finally, and perhaps the most important issue that must be discussed in the debate on overpopulation is the issue of resource scarcity. So called "experts?love to enter the debate and make doomsday predictions that the world will run out of food, or oil, much like Dr. Paul Ehrlich did in his book, The Population Bomb. However, these predictions never seem to come true. Julian Simon, an economist, has an idea about natural resources which has sparked mountains of debate from both camps in the overpopulation discussion. Simon asserts that all natural resources are infinite. While this claim may seem audacious at first, it becomes clearer exactly what he means when studied. His point is definitely not that there are an infinite number of gold or copper atoms in the earth. The mass of the earth is finite, and current scientific studies imply that even the mass of the universe is finite. Simon is saying that resources are indefinite in the sense that we will never run out of them for whatever we decide to use them for. This contradicts the environmentalist wackos who claim the more of a resource is removed from the earth, the scarcer that resource becomes. For example, copper has been used for thousands of years for a variety of uses. The amount of copper taken from mines has increased over the last few thousand

Describe law and order in London in the late nineteeth essays

Describe law and order in London in the late nineteeth essays The police solved crimes by relighing very heavily on a huge network of information who roamed the dark streets of the east of London also they did door to door knocking and asking residents for answers, their was careful searches and enquiries which revealed very little because their were no real whitnesses to the Ripper attacks. The police had a tough image as they didn't carry weapons on the streets, when the police was scared they were eager to resort to the army. Capital punishment was meant to stop deter criminals. (The threat of capital punishment or transportation). The number of crimes punishable by death had reduced from the early nineteenth century of about 223 crimes to 50 by the end of the century because it was clear that these punishments didn't work. The polices reputation was not respected because in investigations the police showed force and made no nonsence approaches and were very tough mainly only the unruly poor e.g. in 1887 a mass riot of the unemployed in Trafalger squarem, which sir Charles Warren suppresses through military force. The police investigations on crimes derived from the politics. Corruption had been uncovered in the higher areas of the CID. The met police were regarded as an increasingly militaristic force as the press had supported the forces and law and order in cracking down mainly in the unruly poor then began to support the working classes. Societys problems was that there was too much alcoholism in the streets and alot of thefts and alot of pick pocketing, other society problems was that there was over 1,200 prostetudes in the streets and in doss houses so the crime rates had been rising. Crime is rife because there is so much unimployment and it is increasing so it means that people need the money and the only way of getting money is to steal from people and places. Crime is also rife because the streets were like mazes and dark also very crouded, their was dirty side streets and a...

Micro hydro power design Case Study Example | Topics and Well Written Essays - 3000 words

Micro hydro power design - Case Study Example n towards production of more environmental friendly energy as oppose to the use of oil, these includes all renewable energy sources such as wind, biomass, solar and more importantly hydro power since it is the most efficient way of producing power in large quantities without damaging the environment (U.S. Department of Energy, 2008). Water is the most abundant resource in the world and as result its energy, in the form potential energy can be dammed and utilized in production of electricity. The dam retains the water and the potential energy rises as the height above the base increases, this water is directed to a turbine by the use of penstock and after working on the turbine, it exists through the tailrace. The critical parts of the turbine includes the caps connected to a shaft, the flowing water exerts a rotary motion on the caps/blades, which causes the shaft to turn in a circular manner. This shaft connects to a generator with a core trapped in a magnet’s poles, which causes electromagnetic induction (USGS, 2008). This electricity generated is then transmitted via cabling to households or for other purposes. In summary, the flowing water and the generator forms the backbone of the hydropower. The water provides the force that turns a rotor with field windings. The windings are supplied with an excitation voltage to set up an electric field, with the rotation of the, magnetically induced current flows to the stator which is a cylindrical ring encased with another magnetic windings. The two windings are separated by about 2mm air gas (USGS, 2008). Today, hydropower systems are cable of producing power ranging from 1MG to 100MG with more possibilities of producing power in small scale with low flow parameters and micro generators. Small dams, commonly known as weirs are used to trap and retain the water, which is then directed to a turbine via piping systems, the generator that produce power for residential usage then utilizes the force.
