Carbon Dioxide


co2Sources of carbon dioxide emissions can be either human-caused or natural. Natural sources of the emissions are beyond the control of the human beings. However, manmade sources are caused or attributed directly or indirectly to the human action. Most of the products’ production processes in the market use a source of energy that involves emission of the carbon dioxide into the environment.

Therefore, the actual producers of the carbon dioxide and the users of the consumer products whose production entails emissions are related directly and indirectly respectively ('Carbon dioxide emissions rise to record levels', 2008). Production processes that contribute to the production and emission of carbon dioxide are; energy generation from coal and natural gases, transportation (using motor vehicles, shipping & air travel), cooking heavy construction, mining, heavy construction etc. all the production process account for the majority of the products that are used by the average person.

Energy generation

Energy generation in the most parts of the world entails burning of some fossil fuel. As a result, there are many carbon emissions resulting from this process. 87 percent of the world is responsible for energy generation using the fossil fuels ('Trapping and keeping carbon dioxide emissions', 2013). In order to generate the energy, fossil fuels are subjected to combustion process at high temperatures whereby there is combination of the carbon part of the fossil fuel with oxygen from the air to form carbon dioxide.

Generation of electricity uses coal to produce heat, which is then used to boil water to produce steam. The steam is produced at a high pressure. For a reason it is ideal for turning turbines, which in turn generate electric ('Low-carbon footprint', 2011). All forms of energy that come from burning of fossil fuels such as coal and a natural gas are sources of carbon dioxide that is emitted into the environment. In some cases, there are backup generators that are used to produce energy during the power outages. Backup generators are designed to use either gas or gasoline. Both are fossil fuels and their combustion releases carbon dioxide into the environment.

The actual production of the fuels is another source of emissions. In the oil mining process, natural gas is usually located at the top of the oil deposits due to its less viscous nature. This aspect makes it the first one to escape. Some of the mining fields have oilrigs that are not well equipped to tap the gas ('Trapping and keeping carbon dioxide emissions', 2013). As a result, they burn it as it comes out to avoid its escape into the environment.

Burning of the excess natural gas creates two predominant issues. The miners can let it escape into the environment and avoid the burning process ('Low-carbon footprint', 2011). Alternatively, they can burn it. Letting the gas escape is precarious given that the gas is a more potent as a greenhouse gas than carbon dioxide. Burning it is the lesser evil of the tow since there is chance of cleaning up the environment using plants ('Trapping and keeping carbon dioxide emissions', 2013). Therefore, the use of electricity produced from fossil fuels contributes to the emissions into the environment.

Transport sector is the second leading source of emissions. In the sector, almost all the main means of movement rely on the combustion of one fuel or the other. Fossil fuels used in the shipping, air and motor travel account for a significant part of the individual carbon print. Every person relies on one mode of transport in one way or the other. In the transportation of major bulky goods, the shipping mode is preferred ('Low-carbon footprint', 2011). Most of the ships use diesel as the main source of fuel for the engines and other electricity generators. Due to the high carbon content in this fuel, the major shipping lines are responsible for the most carbon emissions in the transport sector. Use of any mode of transport increases the carbon print. Domestic use of natural gas for cooking and heating in cold places accounts for the majority of the individual’s carbon prints.

Electricity: how it has changed the world


ELECTRICITY: HOW IT HAS CHANGED THE WORLDThe greatest scientific achievement that occurred in the 19th century is the discovery of electricity. It is necessary to note that in the 20th century and the 21st century electricity has completely changed the face of the earth. Electricity has become extremely useful and has changed the life of people since the day its discovery. Humans have been able to create an intimate relationship with electricity; this relationship formed to the extent that it has been impossible to separate electricity and humans. Individuals often accustomed to the use of daily utilization of electricity such as the illumination of houses, switching on the televisions and getting worldwide news, powering other electrical products such as phones and the cooking of food. This paper is going to describe the origins of electricity and how electrification has impacted the society.

Arguments that although they did not fully understand what electricity was, the ancient people knew some bits about it. Thales of Miletus is the first man to study electricity. He was the Wise one, and he belonged to the Legendary Seven wise men. He studied electricity by rubbing amber that came from a fossilized tree resin with fur. With this, he was able to attract feathers, dust as well as other lightweight projects. This formed the basis by which electricity would be later studied (Peacock, 1882). In fact, it is important to note that the word electricity originated from the Greek word electron which meant amber.

There was a pause in the study of electricity, however, in the 17th century; there was a revival and a renewed interest in this field. Scientists such as William Gilbert conducted experiments to try and study static electricity and its relation to magnetism. Gilbert concluded from his experiments that indeed there existed a fluid in the electricity. This notion and thought continued into the later 1700’s where the scientific community started to get a lucid picture of exactly what electricity was, and how it worked.

The advent of the coulombs law that said that states that like charges repel and opposites attract had its creation during that era. Thomas Edison invented the light bulb, and from there on, electricity progression is on the increase its many sources of production discovered. The current society cannot be able to live without electricity, and they have all right to thank these scientists who had a point of better understanding electricity, and its subsequent production.

Electricity can be described as a set of physical phenomena associated with the presence and the flow of electric charge. Electricity often gives a variety of effects such static electricity, the electromagnetic induction as well as static electricity (Peacock, 1882). It is also necessary to note that electricity often permits the reception and the creation of electromagnetic radiation, which includes radio waves. Since Thomas Edison discovered electricity, the electricity has found tremendous and every growing number of uses.

Electricity is a convenient way when it comes to the transfer of energy. The invention of the practical incandescent light bulb in the year 1870’s and it led to the lighting being the first publicly that is available in the applications of electrical power. Hundreds of years ago, the people never imagined that they could make their lives easily through technology; however, in the modern day people cannot be able to survive without technology. There are several aspects of the human life that electricity has been able to improve a lot and have a lot if impact.

The modern society would be incredibly different if electricity did not exist. One cannot imagine how, for example, the world would be very different without the internet. The World Wide Web is as a result of electricity, and it has had a huge effect on the lives of people. It has made the people of the world aware of the world that they are living in, and it has also made people of the world be aware of the world and the modern society on how it works. The Worldwide web is the gateway to knowledge, and it allows people to find nearly anything in the world in a matter of few seconds (Peacock, 1882). Therefore, electricity has made people to be incredibly intelligent and aware of the society in which they reside.

The first area to be somewhat affected by electricity is communication. It is imperative to note that the ability to communicate has forever been at the heart of the human endeavor, its development and its achievement. In the 1800’s, the driving force that was behind the use of technology was the improvement of the speed and distance over which persons could communicate with the military (Parker, 1992). Electricity played a very huge role in this endeavor as there was the communication of networks in different countries using a system such as the optical telegraph, semaphore as well as the mechanical telegraph.

The construction of the electrical telegraph was one of the milestones in the 1800’s as far as the pace of communication were at stake. The construction of this electrical telegraph was by Cooke and Wheatstone which exploited by the discovery of Michel Faraday’s electro-magnetism. With the invention of this electrical telegraph, a revolution had begun. In the United Kingdom, there were over 1300 telegraph stations which helped in the communication of over 10,000 miles of lines of telegraphs. Within four, years, there was the growth of 5,179 stations, which had in them over 87,000 miles of the telegraph of line.

Since the invention of the telegraph, electricity has continued to advance communications and make it more sophisticated. Therefore, it can be argued that communication is the most improved aspect in the current world. The evolution has come a long way from the electrical telegraph to computers and mobile phones. The human race is a global village people in the 21st century often communicate with each other whenever they want, and no matter the distance that exists between them.

It has become extremely difficult to imagine the world without electricity; this is because the current communication levels that the world enjoys presently will all disappear. News spread in an instance, for example, during the fateful 9/11 attack on the World Trade Center, the information spread to the world in a few minutes and people started to donate blood. Therefore, it can be seen that indeed electricity has indeed impacted the lives of people through its creation of faster and more reliable communication methods.

Electricity has impacted how the human society spends their leisure time. Before, the advent of electricity, people often read books, played physical games and told stories for fun and relaxation. However, with the advent of electricity, this changed abruptly. The human society, for example, in the early 1900’s changed to the use of radio as their main form of entertainment (Peacock, 1882). People would usually sit together and switch on the radio from where they would derive their pleasure and relaxation. With time, the ways of how leisure time is spent has continually increased in sophistication.

Before the advent of the electronics, persons often found simple ways in which they would entertain themselves. The most common forms were knitting by the fireplace, listening to the radio and playing bridge. However, in the second half of the 20th century, electricity has been able to revolutionize the way the human society spends their free time. For example, thanks to companies such as Microsoft and Sony, people can play video games and compete with other gamers around the world. Further, as far as the music goes, there has been the invention of the compact disks and cassettes in the 20th century (Bidder, 2007 ). In the 21st century, this has changed as there have been the inventions of the portable music players which have completely redefined the way people listen as well as access music.

The traditional paperbacks and hardcovers are now a thing of the past. Although sold, the world is slowly inching towards electronic books. For example, the site that is Amazon Kindle gives people access to over 300,000 books at any given time. Further, one can comfortably adjust the font size of the text that they are reading and even change the language. Therefore, it can be seen that indeed electricity over the years has impacted heavily on the entertainment scene.

The invention of the television has also completely changed the culture of the human society. Watching television often enlightens the public on social issues, political issues as well as economic issues that are currently going on in the world. Further, it often does this in a split second and gives a lot of information to the world (Parker, 1992). The watching of movies and films has created another way of how people can be able to spend their leisure time, people nowadays when they are in the dating period often go the movies as a part of their relaxation program. Consequently, it is right to argue that indeed electricity has been able to make entertainment possible; it has created an exciting and fascinating world.

Electricity has been pivotal in the health treatment and services section. This is because it has changed the way people are usually treated and the machinery that exists in hospitals that are used for treatment. In the past, people took herbal medicine that was not even manufactured but instead it was raw from the source (Cadena, 2002). This has changed over the centuries, and the medical technology has considerably improved. In hospitals, surgeons are able to carry out their operations in an effective as well as efficient manner. This is because there is enough lighting as well as the existence of electrical equipment that help in the maintenance of the heart beat as well as the stabilization of the body.

There are several tools that completely revolutionized how medical procedures are successfully done. For example, there is no single item that identifies a doctor like a stethoscope. The stethoscope uses static electricity and for centuries, physicians often relied on auscultation and percussion (Parker, 1992). Also, equipment such as the diagnostic imagining has also transformed the whole health care industry. The machine helps in the diagnosis of diseases; the X- ray is one of the most famous examples of the diagnostic imaging machine. Further, there are other computerized diagnostic imaging machines such as the CT and CAR scans, the MRI, and even the ultrasound. All these, have changed the way in which medicine is conducted, and have generally improved the general health of the public.

The electrocardiogram referred to as ECG and sometimes EKG used worldwide as a way of diagnosing the heart conditions. An electrocardiogram records the small electric waves generated during heart activity and therefore, it becomes extremely easy for doctors or the medical personnel understand and detect abnormal activities in the heart. It is significant to note that a healthy heartbeat initiated by a pulse of electric current is what is considered normal, this tiny electric shock then spreads through the heart and makes the heart muscles contract. The ECG is important as it enables the measuring of how the heart is beating and whether the heartbeat is regular or not. If it is not regular, the medical personnel and doctors can be able to take action in order to ensure that the patient gets stabilized and the causes of the abnormal heartbeat understood.

In conclusion, it can be argued that indeed electricity is an integral utility as far as the modern society is in question. Electricity is the mother of most modern inventions, it has completely changed the way the world is and how it will be in the future. It has impacted the society in more ways than one. It has been able to establish links to everything, from the springing of the human’s subconscious fear of the dark to what can only be said as the practical need for working illumination in the industrialized world (Dowswell, 2002).

The whole world in the 21st century essentially runs on electricity it is the backbone of economies and one of the most significant factors when it comes to production. Electricity has not only been ingrained in the life of the people but also it has become critical for the continued existence of the human race. Electricity can be described as the future; however, it is also the past and present. Most medical treatments and procedures are often commonplace today; however, it is extremely difficult to understand how they could work without the modern lighting and power.

Lighting alone can be described as the backbone of civilization, and it paves the way for extended work capabilities. It has also enabled the development of the certain household goods that are important in order to enable comfortable living. Therefore, this paper has shown that indeed electrification has impacted the world in a great way, electricity has been able to run the world with world governments, financial institutions and corporations all relying on electricity for direct trading, commerce as well as communication. The grip that comes with electrification has extended to the seemingly insignificant aspects of the average citizen such as the use of mobile phone for communicating, and the ability to cook indoors with electricity.
