The Case for Nuclear Fusion As of now, 80% of global energy is provided by fossil fuels. Wind and solar energy sources are unlikely to completely replace fossil fuels in the coming decades due to infrastructure problems. A drop in global energy provided by oil starting sometime between 2012 and 2014 (Chris) is also expected. As a result of these circumstances more research must be done in other forms of energy generation in order to keep with energy demand as countries industrialize and populations grow. Despite claims that nuclear fusion will not be practically realized, research into nuclear fusion should be increased as it is not harmful to the environment, has nearly limitless fuel, and is inherently safe. Fusion power produces no greenhouse gasses and no long-lived radioactive products, making it a very clean energy source. According to the article “Safety and Environment,” “Fusion power does not produce any greenhouse gasses (GHGs) or other atmospheric pollutants during operation.” It has become an increasing desire for things, such as cars and companies, to become environmentally friendly or “green.” The fact that fusion power would generate no greenhouse gasses inherently is a big plus. Furthermore, according to the same article, “SEAFP concluded that fusion has very good inherent safety qualities, among which... no production of long-lived, highly radiotoxic products.” The radiotoxic products produced by nuclear fission pose a large environmental problem due to storage required. Fusion is much more environmentally friendly than fission because it lacks these products. Fusion power is inherently safer than other forms of energy generation, such fission, as well. As mentioned, fusion produces no long-term nuclear waste. I... ... middle of paper ... ...hat problem. Works Cited Chris. "Can Renewables Replace Fossil Fuels?" GetRealList. N.p., n.d.

Cost and availability of fuel is a considerable factor when dealing with nuclear power. Fission requires an element that can be easily split in a particle accelerator, such as uranium or plutonium. Fusion, on the other hand, uses isotopes of hydrogen atoms, specifically deuterium and tritium, that can be obtained from ordinary water. Uranium ores occur naturally in many parts of the world but must go through a costly purification process before used as fuel. The unprocessed ore contains approximately 99.3% uranium-238, a non-fissionable isotope of uranium, and only about 0.7% of U-235 required for fission. One hydrogen atom out of 6700 appears as deuterium, a naturally occurring isotope of hydrogen with an extra neutron, and can easily be separated from the rest. Uranium-235 is a non-renewable resource that will eventually run out, much like the fossil fuels. The abundance of deuterium and lithium provide a virtually unlimited supply of fuel for nuclear fusion. Therefore, nuclear fusion seems to be the better choice.

Nuclear fusion is the process in which two nuclei fuse together to form a larger nuclei. Hydrogen atoms are usually used in fusion reactions. Fusion releases more energy than fission but can only occur when the nuclei are very hot. The temperature needed for fusion reactions is about 20,000,000°C. Fusion reactors are also called thermonuclear reactors because of the high temperatures. Fusion occurs in three stages; in the first stage two hydrogen nuclei join to form deute...
Deuterium is inexpensively extracted from water, and tritium is produced during the reaction itself via lithium. Deuterium and lithium are placed within a containment field created by two large electromagnets, with water below, and the two are heated until they become highly ionized gas, or plasma. From there, the heat is maintained until the two sets of plasma come together, or fuse, and release a burst of energy that surpasses all other methods, including nuclear fission. Nuclear fusion is a safer method of nuclear power, as the isotopes are proven stable both alone and together, are not exceedingly radioactive, and do not pose any known threat of pollution. Alongside this, nuclear fusion is an “intrinsically safe [fusion] reactor operation” as a combination of the “sensitive temperature-pressure balance requirement for reactions to occur” and the minimal amount of material necessary to produce energy ensures that “even in the event of a loss of coolant or power-failure, there is no danger of runaway processes caused by uncontrolled chain-reactions, avoiding the possibility of major accidents.” (“Fusion” 10) Nuclear fusion can be considered a method of harnessing renewable solar energy, and easily complements not only the existing solar initiatives, but those of wind and hydroelectric power as well. (“Fusion”) Currently, nuclear
Therefore, the initial excitement for space-nuclear power sources was quickly ended by uncertain requirements, and the broad range of more feasible technical approaches was researched.
Fusion is an experimental technology for producing power. Therefore, the only product that is created during the nuclear fusion process is helium, which is not a green house gas. This is a great for the environment and our atmosphere because it does not contribute anything to the global warming problem. Also this product is safe and non-toxic, and it is one of the biggest benefits of using nuclear fusion, rather than nuclear fission.
Fusion is quite different then fission. However, it is also a big part of nuclear physics. Fusion is the process that makes power for the sun and stars. It is the reaction that involves two similar atoms combining to form a different atom.
For many years we have used energy to power our houses, cars, and cities. Most people are concerned with the energy we are using kills our planet. We have developed ways to combat that issue using natural renewable resources one example is nuclear energy. Nuclear energy is generating electricity from an atom’s center, or the nucleus. There are two ways to harvest the energy, though fusion, and fission.

I think that right now, fission is the only way that we can get more
Nuclear energy is a topic scholars and the average person discuss and argue whether they are for it or against it. Inside the nuclear reactor, energy is produced by the fission of Uranium atoms. Other isotopes of Uranium and Plutonium are used in reactors. Fission is the process in which a single atom of Uranium absorbs a slow neutron causing it to become unstable and split into two nuclei causing a chain reaction of splitting. A massive amount of energy is released when the atom splits. It is then captured and turned into electricity. Nuclear energy supplies an abundant amount of power for the United States, but there are still problems with this type of energy. During the process of fission, radioactivity is released and the used Uranium rods are still extremely potent to the environment. This waste from the nuclear reaction is what is causing all the debate between people because the waste has not been able to be stored or handled safely without some risk. If the radioactivity is let out into the open, the byproducts are hazardous. Personally, I support the continuation of the United States’ implementation of nuclear power because there are ways to safely use, handle and store the waste; the nuclear reactors are well protected, there are good and bad effects from the production of power, and there is a way to address the public sentiment of those who oppose it.
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”).
