Over the past one hundred years electricity has grown to become the sole driving force behind society. Increasing technological advancement and the growing availability of technology will require a viable energy source to meet the growing demand for power in the coming years. Our current primary source of energy is obtained from the combustion of Fossil fuels such as Coal, Oil and Natural Gas.
The effects of this are not only detrimental to the environment through the release of pollutants into the atmosphere but Fossil Fuel stores are being diminished fairly rapidly, due to the increase in fuel demand around the world, demonstrating that an alternative source of energy will be required.
Many alternative "green" energy sources are being researched and employed around the world such as Thermal, Hydro and Wind power generation, although with current technologies these power sources are not efficient enough to support a global demand for energy. Currently there is only one other source of power generation that is not only efficient enough to support global energy requirements but also provide an escape from current environmental issues associated with the combustion of fossil fuels. This energy source is Nuclear Power.
Electricity is generated by through the boiling of water for the purpose of generating steam. The steam produced by the boiler is injected at high pressure into the turbine inducing a rotating effect (Decher, Reiner. 1996.), this interaction basically leads to a source for energy conversion and hence electricity.
The issue lies with the source of heat needed for the vaporization of water.
Fossil fuels, particularly coal, undergo combustion for the purpose of generating heat in this situation. The combustion process ...

...n conclusion, Fossil fuels are not only a diminishing resource but also pose large impact on the environment, calling out for a replacement source of energy for electrical generation on a global level. Nuclear power is both a greener source of energy and can be compared to renewable energy due to the high abundance of fuel (i.e. uranium 235) accessible and the efficiency associated with fission process, although the main reoccurring issue associated with nuclear power generation is the disposal an impact of nuclear waste, it is in my opinion that under the conditions that nuclear waste can be contained in a manner that it will not effect the environment or society, nuclear power is the only domestically available power source capable of meeting the global energy requirements of this day and age, thus should be further investigated as an alternative to Fossil fuels.
Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
Energy is undoubtedly one of the most important issues facing the world today. While fossil fuels may produce enough energy at a low cost, they also have severe environmental impacts on the world. Wind energy is a clean source, but is also extremely expensive to maintain. Nuclear energy may be the best energy alternative to coal and oil, with the ability to produce much more energy at relatively low cost, while also being more environmentally sound. Nuclear Power comes from the process of splitting Uranium Atoms (also called fission), which in turn releases copious amounts of energy in the form of heat.
Central Idea: Nuclear energy only contributes a small amount to the world’s electricity yet it has hazards and dangers that far out-way its benefits. There are many other alternative power producing sources that can produce energy more efficiently and more safely than nuclear power plants can.
...lobal warming and innumerable animal fatalities worldwide. Workers in the fossil fuel industries undergo irrational risks of an inevitable explosion every day. Thousands of human lives have been taken in offshore oil rig explosions, coal mines and natural gas pipelines. In addition, fossil fuels are directly linked to rising global warming temperatures and drast changes in the environment. Likewise millions of avian fatalities were linked to fossil fuels plants, emitting greenhouse gases are responsible for acidic oceans that harm marine species, and thousands of animals are harmed by oil spills in the sea. Based on this research, fossil fuels are harming the Earth excessively. Renewable energy sources offer efficient and cleaner energy that will benefit the globe. Renewable energy is the definite solution to end human’s heavy dependence upon ancient fossil fuels.
From the home to factories, families and industries are reliant on the use of nonrenewable fossil fuels to feed the needs of the everyday human. Fossil fuels are the main source of energy over clean, renewable sources such as the use of wind, solar energy, and water to power our homes, schools, and industries. In fact, about 85% of energy use comes from fossils fuels. The main reason being that using fossil fuels is cheaper than wind and solar energy. “For nearly two centuries, fossil fuels have been the cheapest source of energy” and widely abundant (Marburger, A global framework: international aspects of climate change). However, overtime fossil fuels will disappear due to the lack of time to replenish itself with the human races rapid use of it. Despite its current status of availability, there are many controversial issue in using fossil fuels; the most prominent issue being that it is the cause of rapid climate
In conclusion, there are different opinions on the issue of the use of nuclear energy. Nuclear energy is only one of many energy options. Nuclear power can decrease pollution to the environment because it does not produce harming gases like other plants do. However, there are also drawbacks that can influences human health by emitting radioactive substances. Thus, all parties should make a deeper research and analysis based on the argument to decide the use of nuclear energy as a safe and cost effective source of energy.
Although nuclear energy may emit less carbon dioxide as compared to oil or gas, it is nowhere near the alternative energy source we need. A Huffington Post article showed that water shortages, exacerbated by global climate change, minimizes the ability for expansion of nuclear power plants. As the generators require large amounts of water to keep them cool, they must be built on large water sources, mostly rivers and lakes. This reliance on water severely limits the places the nuclear power plants could be built, which makes nuclear an unreliable resource to replace oil and gas in the future as it could not meet all our energy needs. Furthermore, in 2009, France was forced to shut down many of their power plants due to the unseasonably warm summer it had, most likely caused by climate change. As our Earth continues to heat up and more places experience drought, nuclear energy is less and less reliable due to the reliance on cold water. Additionally, runoff from the water flows into nearby water sources, causing thermal pollution to the animals and ecological consequences. Coupled with the fact that we still have no idea how to properly dispose of the waste material left behind from nuclear reactions, nuclear power is not the alternative energy that solves major world problems. This hurts future generations, as we will not only create yet another reliance on an energy source that harms the planet, but divert attention away from truly solving the issue on hand. A Bloomberg New Energy Finance report from early June projects that as early as 2028, solar energy can replace the oil and gas sector demands. The cost of projection would also decrease for both solar and wind energy by 66-71% within the next ten years as well. Solar and wind have considerably less risks to the environment and, regarding these as more possible
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
The effects of using fossil fuels are starker than their timelines. Humans release approximately two billion metric tons of pollution annually, mostly from the burning of coal, oil, and natural gas; this pollution is destroying our environment and the ozone layer. Ozone and smog damage forests, crops, and other plant life, and reduces visibility. Other pollutants have the same
Fossil fuels are an unreliable and unsafe source for worldwide energy. Our common fuels will run out as in: Ethanol, Petroleum, and Oil. Honestly we need those fuels for life, to drive cars, four wheelers, lawn mowers, and tractors, etc. If we did not have those things anymore our ways of living will drastically decrease. People in our society are so use to driving vehicles that if that gets taken away World War III would start. We use lawn mowers to cut our grass, to keep our land in shape and pretty. We also use tractors for multiple things not only to keep big pastures in shape, but also to use for logging. People do logging for a living. Without tractors their job would be very intense.(conserve-energy-future.com)
The burning of fossil fuels has greatly harmed our environment and is a leading cause as to why climate change has become such a threat to our way of living. In May of 2013, the carbon dioxide levels in the atmosphere reached 400 parts per million, an increase of more than 40 percent since the beginning of the Industrial Revolution. This could cause the Arctic Ocean to be nearly ice-free during the summer by 2020(Overland and Wang, 2013).
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
