Sources Of Power
There are various sources of energy available today. Some of these sources are renewable while others are not. The paper will look at the pros and cons of two sources of energy;nuclear power or coal-fired power generation. These pros and cons will be weighed and a choice made between the two sources of energy of which one should be added to a utility system.
Nuclear power
This involves the generation of heat and energy using exothermic processes. This is through nuclear fission, nuclear decay and nuclear fusion. Nuclear energy has become a prominent source of energy today. There are various pros and cons associated with nuclear energy.
Pros
Nuclear energy is carbon free energy. Nuclear power plants emit no carbon dioxide and other greenhouse gases into the atmosphere during generation of power. The operation costs of nuclear energy production are relatively low. Nuclear power is technology that is known this means that it is ready for the market. Nuclear power has a large power generating capacity and therefore it is able to meet industrial needs which are not the case for low-power technologies such as solar that meet only local needs but unable to generate power to be used by heavy, machinery. Any nuclear waste can be reduced through reprocessing and recycling(Presidio, 2009)
Cons
The disadvantages of nuclear energy are the high costs of construction due to complex procedures and radiation containment systems. There are very high risks of accidents and catastrophes that are known.it also takes a long time to construct nuclear plants. Sources of uranium are just as little as other sources of energy like natural gas and coal and are quite expensive to mine, refineandtransport. There is the production of long-lived nuclear waste of 20-30 tons of radioactive waste produced (Presidio ,2009)
Coal-fired power generation
Coal is a fossil fuel that is got from primeval forests that have decayed over a period of time. There are several advantages and disadvantages that are associated with the use of coal-fired power for the generation of energy.
Pros
Coal is easily combustible burning at low temperatures.coal is widely and easily found all over the world. This makes it quite available for much of the world. The process of mining cola is simple thus it is the least expensive fossil fuel. The generation of energy using coal generally scales well this makes it economically possible to build various sizes of generationplants. Coal-fired power plants can be built anywhere so long as there is a large supply of coal (Hall, 2010).
Cons
Some of the disadvantagesare; it is a non-renewableenergy source hence can be depleted burning of coal leads to carbon dioxide being released which is a very powerful greenhouse gas that contributes to global warming. There are also other toxic wastes that are released when coal is burnt that lead to environmental contamination. When it comes to energy density coal has the lowest thismeans that it produces the least energy per fuelton. The transportation coasts with coal are quite high. This is due to the bulk nature of coals. Coal dust is an expositionhazard therefore extra caution should be taken when transporting and storing coal in order to mitigate this danger. Coal mining can lead to environmental damages which are irreversible (Hall, 2010).
Conclusion
As discussed above we see that both nuclear power and coal-fired power generation have their advantages and disadvantages .After weighing the pros and cons of each I would recommend the addition of nuclear power to a utility system. This is because one it does not depend on fossil fuel like coal. This therefore implies that it can not be depleted hence termed as a renewable energysource. Nuclear energy is also not affected by gas or oil prices. Unlike coal, nuclear power does not emit carbon dioxide to the atmosphere. This makes it a clear energysources which does not contribute to climate change (Jeffrey 2011).

Sources of my motivation, self-reflection
At this point in life I can say that my motivation mainly comes from my drive to always want to succeed and be the best at whatever I do. My grandparents ,while I was growing up influenced my personality and values; they taught me the importance of discipline and self-motivation .Their support and resilience has helped me even when confronted with doubt or insurmountable obstacles to persevere and know that hard work and determination is always if not often rewarded. They taught me that the values that we have as individuals are mostly emancipations of the Devine, thus making them more of spiritual skills that our minds and hearts can relate to for more practical applications in daily life. In addition through the combination of positive personality and values each individual can release unlimited potential for happiness and accomplishment. I can say that these teachings that border in recognizing the existence of a supreme being has helped instill in me a more active sense of morality and self- awareness that has helped me navigate and shape my life towards a more positive direction both professionally and socially. Therefore my motivation in life originate from the teachings my grandparents instilled in me that till today I still use as my greatest source of motivation to check my values and beliefs (Eland, 2001).
Over the period of the 21st century the culture of the people in the United States has drastically changed. The Americans can be described as embracing a culture that is powerful, strong and influential due to this dynamism it has allowed the people to freely embrace selflessness, positive values that allow more room for expression in all forms, and hospitality as exhibited by the way they embrace their daily way of life. The impact the American culture on me as an international student from China was one that could be described as intellectually stimulating, personally rewarding and exhilarating and sometimes exhausting. Living in this new fast paced culture helped shape my attitude toward my initial goals and values that I had as I left my country. It was quite hard to function and live here, with the unfamiliar imposed set of norms. Example As an international student the new language that everyone was using mainly English presented a challenge, and in this aspect it made it hard to integrate in the new life both socially and academically.
Just like with all the other international students striking a balance between the new culture and the initially held beliefs and value systems initially practiced becomes a challenge and in this manner necessitated that a balance has to be struck so as not to be fully absorbed into the new culture. This new way of looking at things, both in terms of value, goals and culture helped broaden my way of interpretation behavior and interactions to be able to cope with the new situation. It required paying immense attention to my surroundings and my communication methods refining and expanding my interpersonal cultural communication skills to be able to effectively coincide with that of the locals. In this way the culture in which an individual lives or is introduced to is directly influenced by their personal reality and this determines whether they get stunned by the culture shock and influence on their belief and value systems they initially held.
