Alternatives to fossil fuels Essay

The conventional source of faculty like coal, the petroleum, etc, bequeath probably be exhausted up within a clock that the humanity might foresee. In addition, according to Hordeski (2002), fogy fuels such as petroleum, natural gas, coal must be discovered and excerptioned before they seat be conducive to mankind. This is a existly and time-consuming job. Meanwhile, the quantity of these fuels is limited. Therefore, it is proven that the global resources consumption is undue.Their supply is virtually unlimited or they undersurface be replaced as needed. Beca single-valued function of less contamination, recycling, larger major creator and higher efficiency, the atomic power seems to be more than a good choice definitely. This stress entrust first outline the effects of the over-consumption of global natural resources, which falled by going to assess the viability of using atomic power as a utility(a) in a long-term. Last besides not least, the evidence testamen t point out that the measure should be first considered as a priority currently.Abundant clean zip is all that frequent expected in the modern time. As a parvenu talent, atomic power plays an primary(prenominal) role in the current world. Kurdsunoaeglu (2000) points out that thermonuclear power devisets generate electricity without release of chemicals which ca uptake atmospheric pollution and global warming. However, using nuclear technology more effectively testament probably help people avoid such danger and threat. Moreover, burn fossil fuels continually, which place carbon dioxide in the atmosphere, will ca handling changes in the climate that maybe catastrophic for human. Furthermore, the escalating price of fossil fuels will bring about the price of everything else the location of the remaining reserves is the source of much of immediatelys international disorder (A white-hot elephant 2006). Therefore, exploring the nuclear power has sprain the pressing proje ct to face for the aim of less pollution.Beca occasion the vigor reborn comparatively balance, the nuclear elan vital can be recycled. Recycling the nuclear power will reduce harmful emissions. Furthermore, people could make use of good things of small quantities of emissions which so much as argon fair thrown away as waste. The president of Spain has agreed to a widely consultative process to find a solution to what to do with quick radioactive waste (Spain says Adios to nuclear poweFourth European rude to begin phase out 2006).The effort would lead to a modern energy system that will save more energy during transformation. atomic energy is obtained by nuclear fission and radioactive decay, both of which extract energy with a costless way, and besides bring us an alternative choice of energy source without any pollution. On the other hand, the shipway of recycling the nuclear power are comprehensive. Under the modern technology, industry, agriculture, environmental prote ction, health and medical community, scientific research are all anxious(p) for the technology of recycling nuclear power. At the present moment, the function this technology has drawn out its maximum utility in some fields.Compared with other alternatives, nuclear power can produce bigger energy. Studies show that the broad(a) annual solar energy input to the earth is more than 15,000 generation as great as the earth current yearly use of fossil and nuclear fuels. The term photo electric comes from the Greek word for light, photos and voltaic which refers to the unit of electromotive force. The discovery of the photovoltaic effect goes back to the French physicist Becquerel, who conducted experiments with a wet cell battery and found that the battery voltage change magnitude when its silver plates were exposed to sunlight (Hordeski, 2002). On the face of this fact, once all in all put it into the use, nuclear power will display the energy with the derive that beyond imaginatio n.According to Hordeski (2002), Nuclear power stations operate on the same linguistic rules as fossil fuel plants except the heat from the fossil fuel is replaced by a heat from a controlled nuclear reactor. This style if only the produce of energy conversion keep balance, nuclear power can keep a higher efficiency. Opportunities for nuclear power are distributed broadly around the world, and nuclear power can help to sell concerns over sustainable energy resources (Advertising in Cooperation in the zip fastener Futures of chinaware and the United States, 2000). Engineering a modernistic energy system will provide stewardship for all life on earth. Renewable energy is effectively infinite in supply.Presently the cost of using nuclear power is very high. This is due to that using the nuclear power needs a very high scientific and technological content. The deficiency in this plan is very clear. The process of using nuclear power is very complicated. Energy is generally divided into two categories stored and transient. The stored forms of energy are potential, kinetic, internal, chemical, and nuclear. Chemical and nuclear energy represent the energy bound up in the social system of the molecular and atomic compounds (Hordeski, 2002). In the long and complicated course of exploring and using this energy, the sufficient manpower, physical and financial resources are unprecedentedly needed.The risk understood exists in using the nuclear power. Elliott (1997) stresses the longer term prospects for nuclear power are unclear. Fission reactors use a fuel (uranium), which although still relatively abundant, will not be available indefinitely fast breeder reactors, which in effect would stretch the availability of the fuel, have yet to be operated commercially and pose what some people regards as significant safety and security risks. Finally, nuclear coalescency remains a long-term possibility, but as we may predict that, even if the technology comes to be per fect, it as well as has problems. As discussed by (Cimbala, 2000) nuclear optimists assume that these states will reason as past nuclear powers have about the costs and risks of nuclear brinkmanship or war, the international society still have to collection for an effective and peace-loving way in using nuclear power resources in behalf of benefiting the humanity.The challenges of nuclear power are widely recognized to be in iv aspects cost, operational safety, the safe disposal of nuclear waste, and the prevention of the proliferation of nuclear weapons (Advertising in Cooperation in the Energy Futures of China and the United States, 2000). Focus on these foursome challenges, there are several available solutions to deal with.Firstly, the governments may use mass media as vehicles for propaganda to support the peaceful use of nuclear energy enhance the use of nuclear energy security and persist the principle of use nuclear power. Bent, Orr and Baker (2002) claim that if nation al leaders explained the grandness of ontogeny a sustainable energy policy, and pushed hard for one, the people would follow their leadership. Most people are keenly aware of the urgent energy challenges and are prepared to make sacrifices to ensure that the world has an adequate, secure, sustainable, and affordable energy supply.Secondly, every country should be dedicated to produce a new energy system to develop the new technology and reduce the cost of nuclear power. A fully implementation of this system would stop the use of fossil fuels and launch an entirely new energy infrastructure. An economist, Joseph Schumpeter makes convincing arguments that new products and innovation are the driving force of an expanding economy (Robert, 1992). The universities which are fit with high quality research offices should set the specialized field to appeal for more talents who design to be nuclear experts. The educational policy will advance the development of the top technology.The third point, increasing funds for scientific research to improve the use of nuclear power and technology is another(prenominal) important policy to support the reasonable use of nuclear power. Laurence (2002) maintains that serviceman Technologist must implement the energy system that utilizes no fossil fuels. An energy system based on renewable energy and fusion reactors has been proposed. Governments should establish special funds to support this scientific research. In addition, the public should be educated in how to use energy more effectively, because it is important to bear in mind that making the nuclear power mystify the focal point in the area of energy utilization in the future is an essential work for all the world.In conclusion, facing the environmental concerns and energy shortage, seeking available alternatives to replace the conventional energy sources shapes an urgent matter at the present time. There are several energy resources that are renewable. People have to fin d long-term alternatives to substitute fossil fuels to overcome the new energy challenges. Thus, nuclear power is going to become a new energy which has comparatively more powerful energy and higher efficiency. However, the use of nuclear power has some flaws.As mentioned in the former part, it always goes with the higher costs, potential risks and desires for highly advanced technology. cladding these problems, scientists are drawing some strong points to offset its own weakness, devoting themselves to developing the nuclear technology. Besides enhancing the use of nuclear energy security, the governments are also required to increase the funds to support the scientific research for making nuclear power more effective, safer and more economical to serve humanity.
