One of the most important problems the world is facing today is limited supply of energy resources. It is generally agreed that oil, coal and gas will come to end after some time; therefore it is essential to find a replacement for fossil fuels before they are exhausted. Scientists have carried out many researches, and one of the proposed solutions is nuclear power. Nuclear energy, or atomic energy, is produced in nuclear reactions, when nuclear particles collide with a neutron and explode, emitting energy. Its important characteristic is tremendous efficiency, such that great amount of energy can be generated from small amount of nuclear fuel, which makes it efficient and long-lasting. Nuclear energy was discovered in late 1930s and was initially used to build atomic bombs, however after the Second World War it started to be used in production of electricity. Most of people have a prejudice against nuclear energy because of atomic bombs and accidents on nuclear power stations. They think that it is risky and unreliable, when in fact modern technology can provide safe usage of atomic energy. This project will investigate the advantages and disadvantages of atomic energy, suggest possible actions to improve security measures of nuclear power and determine whether it can be a safe substitute for current fossil fuel energy resources or not. Nuclear power could be more environmentally friendly than other energy resources. First of all nuclear reactors produce relatively very small amount of greenhouse gases, such as carbon dioxide, nitrogen oxide or sulphur dioxide(Hinrichs and Kleinbach 2006). Holger Rogner (2010) states that nuclear reactors emit only a few grams of greenhouse gases during production of a kWh of electricity, this... ... middle of paper ... ...s only one reactor and produces 73% of its electricity. Nuclear energy status in Russia is not high; it produces 17% of its electricity by 31 operating reactors. (Schneider et al. 2009) Most of these countries have nuclear waste management programs and nuclear industry expanding plans. (Schneider et al. 2009) High status of nuclear energy in developed countries shows that nuclear power could become main electricity supplier. In conclusion, nuclear energy can be a safe way to yield electricity. Modern reactors and international safety measures can avoid most of perils of nuclear energy. Nuclear industry is developing and improving safety and security measures, which regulate proliferation, waste disposal and ageing of nuclear power plants. Moreover environmental and economic benefits demonstrate nuclear power being preferable substitute for fossil fuel resources.
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.
One of the many benefits of Nuclear energy is that it is completely emission free, in fact, more than 70% of the clean energy produced in the United States comes from nuclear (“11 Facts about Nuclear Energy”) With those lack of emissions we will see a reduction in the
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.
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
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...
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need for energy in today’s current world, exploring different ways of producing power is necessary. The differences and similarities between nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production. To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”).
Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
Fuel alternatives for the future are very important because, we need resources for life. We won’t have fossil fuels forever. It is important to start now. If we did not have any fuel alternatives how would the world be?
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.
Though it might seem that the world’s energy supply is secure as of the present, this issue is something that is beginning to worry even the richest states. “Countries as far apart as South Africa and Tajikistan are plagued by power cuts and there have been riots in several nations because of disruptions to electricity” and “rich states [are] no longer strangers to periodic blackouts” (ElBaradei). If we look again at the breakdown of U.S. electricity generation by energy source, it is evident that nuclear power is the next most substantial chunk of energy generation, with other renewables weighing in far behind that. I believe this begs the question, why do we not expand nuclear power to encompa...
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
