Nuclear Fusion: the Premier Solution to Climate Change The search for a viable source of renewable energy is a centuries old affair. For the entirety of that time, the research has been met with opposition from both a political and economic standpoint. To present renowned scientific evidence of its existence and impact was to invite accusations of fabrication. To simply state, as former United States Vice President Al Gore famously put it, “[the] inconvenient truth” that a culture of consumption will have dire consequences for humanity’s future was heresy. For years, those in industry lobbies, and politicians in corporate pockets, have shot down legislative attempts at utilizing more conservative energy options. However, the urgent warnings …show more content…
(“Radiation”) Since the field of nuclear fusion is constantly evolving, stringent safety regulations are smoothly expanded upon and have the added bonus of increasing efficiency and accessibility. Alongside this, nuclear fusion is being developed with a heavy focus on safety, purity, and efficiency. (“Fusion”) This effort is readily exhibited when compared to nuclear fission. Nuclear fission primarily employs fissile isotopes of radioactive elements. (“Sustainable” 3100) These isotopes are far more open to instability and proliferation. . (“Sustainable” 3100) Another concern that has been repeatedly underscored is iodine-131 (131I). “The fission of uranium produces large amounts of 131I that may be released into the atmosphere in the course of a nuclear accident (2.878% yield of 235U)… [and] can enter the body via inhalation or ingestion of contaminated food or milk.” (“Managing” 4159) Although 131I only has a half-life of eight days, 131I’s ionizing radiation has repeatedly been found to quickly …show more content…
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
The Atomic Age represents the most epic era and composed of diverse controversial issues in the human history. In the late 1945, President Harry Truman informed to drop two atomic bombs on the Japanese cities of Hiroshima and Nagasaki. These two bombs quickly yielded the surrender of Japan and the end the World War 2. However, the impact of it led us to debate whether this decision was actually right or so. First off, it would be hard to imagine how Japan would have been surrendered without the atomic bomb. Therefore to save many American lives, President Truman believed that it was his duty to end the war as soon as possible. But the bombs took away innocent lives and killed civilians indiscriminately. “Atomic Age America” written by Martin
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.
The Big Bang The opportunity to end World War II was right in front of President Truman, but could he unleash the horrible weapon against Japan? Would he be able to use the weapon that was likely to be the most destructive weapon ever used? President Truman’s goal was to end the war as swiftly as possible, and with the atomic bomb, he would be able to accomplish this goal. President Truman believed the atomic bomb would save both American and Japanese lives.
During the late 1930s and early 1940s European countries along with parts of Asia were undergoing World War II. The U.S. had become involved in 1941 when the Japanese bombed Pearl Harbor. To help the U.S. they joined Britain, France and the Soviet Union (Allied Powers) to fight against Germany, Italy and Japan (Axis Powers). In the spring of 1945 the Allied Powers had concord and defeated Germany. The next task was to defeat Japan (pacific ocean war). The war in the pacific was filled with death that the U.S.was not prepared for. These battles foreshadowed the invasion of the Japanese mainland. The results would be a tremendous loss for the U.S. The U.S. had to come up with a plan, the atomic bomb.There are many controversies in whether the U.S. should have dropped the bomb. The U.S. did end
The tragedy of the bombings of Hiroshima and Nagasaki have been nearly wiped from American textbooks, as well as those in Japan, causing many people in the modern world to have little to no knowledge of the fact that nuclear warfare is not just an edgy science fiction fantasy- It was the reality of those who were unfortunate enough to be within the area of the explosions on August 6th and 9th, 1945. The statistics and testimonies given on the nuclear bombings should be more than enough to wipe the idea of the use of nuclear warfare off the list of options during times of conflict and turmoil. In very recent news, there have been multiple threats of the use of nuclear weapons from multiple different countries.
One of the most contest and debated topics in recorded history was the decision by the United States to drop the atomic bomb on Nagasaki and Hiroshima. This essay will research the question was the decision to use the atomic bombs against Imperial Japan truly necessary to ending the World War Two? The reason why a decision made over 60 years ago is still worth investigating today is because of its direct implication the choice made by the United States still has in today’s society. There are still existing tensions between the United States and japan for the usage of the atomic bombs. For example, as of May of 2016, when current United States president visited japan, people were still asking for the United States to apologize for their decision from 1945. Furthermore, the question is worth investigating because of the scale of the destruction of just these two bombs alone. Each bomb was responsible for killing over 50,000 men, women, and children instantly and leaving toxic radiation levels for years to come.
Fortune states that “the solar and wind industries are each creating jobs at a rate 12 times faster than that of the rest of the U.S. economy” (Samuelson 1). The article states that there are roughly four and a half million jobs in the sustainability sector, and the number could keep growing if the United States continues to invest in renewable energy (Samuelson 2). All of these benefits would be considered extra incentives, because the biggest benefit of more renewable energy would be to combat the current climate change crisis. With so many positives, it is surprising that the United States refuses to dedicate more of its resources to expanding clean energy, even when it helps the economy, environment, and sets America up with an infinite source of
The year is 2200. The world is going through a fossil fuel shortage. Oil reserves are almost completely consumed and it is becoming impossible to find new fossil fuel sources. Not prepared for this event to occur, The United States, has no alternative options. As a result of the oil shortage, the standard of living deteriorates. Heat in homes, supermarkets full of food, and transportation, all basic necessities taken for granted, will be depleted because fossil fuels are used to power almost everything. The key to the prevention of this future is renewable energy. Unfortunately the support for the use of renewable energy is weak and ineffective. Unless the US puts forth effort to research and promote the use of renewable energy to consumers, conversion from fossil fuels to renewable energy will no longer be an option.
In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.
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”).
Power from nuclear fusion reactors would be a welcome achievement for the 21st century, and at the current rate of progress it seems likely that before the end of the new century energy will be available from nuclear fusion. It is estimated that it will take over a decade from the time a sustainable fusion reaction is achieved before fusion power will be available for use. But the attention being devoted to research is strong, the experiments are coming closer to fruition, and we are coming closer to having an almost limitless supply of energy.
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
Whilst there are clear arguments for and against nuclear energy, the future is promising; with scientists working on potential breakthroughs such as nuclear fusion, and the design of newer and better and reactors. Nuclear fusion is a reaction which causes the nuclei of atoms to collide and form a new atomic nucleus. It is essentially what heats the sun and stars and would produce no long-lived radioactive waste.22 If scientists could control the process of atomic fusion then it could become a never ending energy source for future use.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
