With the great technological advances in the field of energy production, people are confused about the best source of energy. There is a current debate about whether we should continue relying on coal to produce nuclear energy or whether we should convert to use nuclear energy. People have been using coal energy for many years and there are thousands of coal plants around the world. Later on, people started to use nuclear energy to produce energy such as electricity and according to Schneider (2014), there are around 430 nuclear plants in the world. In order to determine which energy is the best, people have to examine the safety, effort and the cost of the energy. Comparing Nuclear and Coal Energy Safety and preservation of the environment are the most important things that the actors in energy extraction should consider. Nuclear energy is considered a clean energy that does not produce greenhouse gases that harm the environment. According to statistics of U.S. Department of Energy and the Energy information administration …show more content…
Nuclear reactions go through several steps such as a fission process in order to link up nuclear reactions, which make it harder to generate nuclear energy. Additionally, each one of these processes of nuclear production requires strong reactors. In fact, it is too expensive to build nuclear reactors because they should be well prepared to sustain the nuclear reactions. According to Arnold (2011), “the biggest obstacle to building new nuclear power plants lately is the cost. It just costs too much to build a modern, safe, nuclear reactor – especially when you can build much cheaper power plants that burn natural gas”(para. 3) . However, coal energy is cheaper than nuclear energy. Generating energy from coal does not need big and strong reactors because the reactions that occur in coal reactors are not very strong compared to the nuclear
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.
power is not the cleanest energy source. However nuclear energy is cheaper than fossil fuels, and the
Radioactive Waste One of the most talked about opposition to nuclear fission is the radioactive waste it produces. Radioactive waste is what is left behind after using a reactor to make electricity. There are two levels of waste, low and high, but both are regulated by the Department of Energy and the Nuclear Regulatory Commission. High level waste is made up of fuel that’s been used directly in the reactor, which is highly radioactive but can still be disposed of. Low-level waste is the contaminated items that have been exposed to radiation.
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.
When it comes to nuclear war, most people will have mixed feelings on it. Nuclear war is a difficult area to touch on. Whether or not someone sees it as ethically right or wrong, all depends on the person and their moral values. The reason I chose this was because I don’t think it is necessarily right to engage in nuclear warfare even if it is the only means to end war. Just-war theory, utilitarianism, and Virtue ethics all help show a different perspective on nuclear warfare. There are many solutions to it, however. Some solutions are getting other nations to place embargos on the country and forcing peace talks without resorting to military action. Significantly, it is important that nuclear war is addressed in the world so that nations
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.
Not only is nuclear power friendly to the environment, but it is almost always available, and many countries are starting to use it more. Renewable energy sources like solar and wind en...
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.
Nuclear power is the generation of electricity from an atomic reaction. (World Statistics: Nuclear Energy Around the World n.d.) Though it produces zero carbon emissions there has been a decline in support for nuclear power and increased its support for alternative energies in the pursuit for a fossil free energy sector. Factors that have resulted in the reduction of support for nuclear energy include nuclear accidents and waste and the positives of renewable energy which include clean energy, sustainable and reduced health and environmental risks.
Our world today is growing every day every year and there will be a time where more and more energy will be needed to sustain human life. The demand for electricity and its value is increasing rapidly and will only continue to do so. The world will need greatly increased energy supply in the next 20 years, especially clean generated electricity [WNA, 2014]. Fourteen percent of the world’s electricity comes from nuclear energy to use. The use and demand for electricity will increase in 2030 by eighty one percent. Therefore, nuclear power plants need to rise to fulfill the demands and needs for the growth of the population. Since the demand for electricity is increasing and with many resources to get electricity from, the use of nuclear energy without constant support will probably decline to around 9 percent or less by 2035. At least two factors will make this quite difficult for nuclear energy to gain a bigger m...
In 1945, when the Americans bombed Hiroshima, Japan, approximately 140,000 men and women were instantly killed by the effects of American nuclear defense. With such extreme brutality and force how many people must die for one to finally realize the strengths of nuclear bombs and what damage they can cause. Nuclear weapons should be outlawed because they kill thousands of innocent humans at a time, destroy the environment, and inviolate human’s right to moral and personal freedoms.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
Compare and Contrast Nuclear Energy and Alternative Energy. Standard Number Science 3.4. Today, our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed.
The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could result in an energy crisis. Nuclear fission produces highly radioactive waste that is expensive to dispose of properly. Nuclear fusion reactors would produce much less radioactive waste and would be more efficient than nuclear fission, but to date there have been no nuclear fusion reactors that have generated usable energy output. Why is fusion power, which could be very beneficial, so hard to come by?
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
