Nuclear Power is the Short Term Solution The world's natural resources are being consumed at an alarming rate. As these resources diminish, people will be seeking alternative sources by which to generate electricity for heat and light. The only practical short-term solution for the energy/pollution crisis should be nuclear power because it is available, cleaner and safer. The needs for alternative energy are present today with China and India growing in population and increasing their oil consumption. In addition, the demand and competition for oil in a near future will eventually be too great for the supply; indeed, our lifestyles are currently based on inefficient energy devices. This includes automobiles and electric appliances that require high consumption energy-based industrial processes. However, experience in the field of energy has shown that nuclear power is an alternative for our future needs. Further, of all the electricity generating methods, nuclear is the cleanest. This is a fact from mining of the uranium ore to final disposal of the wastes. There is no combustio...
power is not the cleanest energy source. However nuclear energy is cheaper than fossil fuels, and 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...
Nuclear energy is a very powerful source of energy. Just a little bit is required to make large amounts of electricity, which powers 1 in 5 households in the U.S. Nuclear energy has been advanced over the years and has been relied on heavily by many countries today.
Today our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed. 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 of energy in today’s current world, exploring different ways of producing power are necessary. The differences and similarities of 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.
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...
Along the years, the necessity of electrical energy increases dramatically with the use of technologies and machines to help with daily activities, to work or to have fun. In the Industrial Revolution, this process of reducing the workforce to use machines started and problems with environment become a reality. One of them is the most energy resources used in the beginning and now: fossil fuel, which is not renewable. Beside the fact it will disappear, it brings a terrible consequence: pollution. After some decades, people started to worry about these issues, electrical and nuclear energies was developed aiming to solve the problem.
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.
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.
Although it is the irresistible trend to put an end to nuclear power, we could not achieve the nuke-free dream through an immediate action. There are a few essential reasons.
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.
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.
Nuclear power is the usage of nuclear reactions that releases nuclear energy which is especially used to generate electricity. It is considered to be a sustainable source of energy source that reduces the global emissions of greenhouse gases profoundly. Nuclear power stations have begun their operations in the 1950s and to date provides over 11% of the world’s electricity supply. Nuclear technology is mainly used in the production of electricity in nuclear power plants in order for the necessary transformation to the 21st century energy-supply system.
By 2025, the use of nuclear energy to generate electricity is expected to increase about 3% from the current percentage of a little over 1. If we can find a way to dispose of and properly handle nuclear waste, nuclear power can prove to be a very promising alternative energy source in future.
... usage is currently generated from. Unfortunately, fossil fuels are not sustainable, and are estimated to diminish in the 2080s. Therefore, it is necessary to make the transition to at least one other source of energy in order to maintain our ever increasing energy demand. One of the possibilities lies in nuclear energy, which splits into two main categories, nuclear fission and fusion. The former is also not sustainable, but is capable of meeting our power needs for about a hundred and sixty millenniums. The latter is considered sustainable, and if made possible, it may be the solution to the initial problem of finding an everlasting, clean source of energy. However, nuclear power is facing difficulties in getting accepted by the public. Finally, shifting from fossil fuels will have a positive impact on the environment through the reduced greenhouse gas emissions.
