The world’s largest source of emission-free energy is nuclear energy. Energy sources like solar power, wind power, and hydro electric power are also good ways to produce clean energy; however, when it comes down to it they can’t produce the capacity of energy the world needs. The two largest problems with fossil fuels are that they are running out and produce greenhouse gases when burned. Greenhouse gases are gases that absorb and emit radiation inside the atmosphere. The main greenhouse gases in earth’s atmosphere are carbon dioxide, water vapor, nitrous oxide, methane, and ozone. Ultimately greenhouse gases are a good thing because they keep the earth warm enough to have a wide variety of climates; however, when our energy sources put excess amounts of these gases into the atmosphere we speed up the process of global warming. By switching to nuclear energy we can keep our air clean, which will preserve the earth’s climate. Nuclear or atomic energy, was originally discovered by French scientist Henri Becquerel in 1896. The two major uses of nuclear energy are as a power source and for weapons of mass destruction. The basis of nuclear energy is the splitting of an atom (the smallest particle of matter), which releases massive amounts of energy. A nuclear reactor is the device designed to start and control nuclear reactions to generate electricity. As of now, the most common type of reaction to generate energy is nuclear fission. Fission, which is the splitting of nuclei, creates more than 10 million times the energy that is created in the burning of fossil fuels. Fission reactions are able to generate electricity because they produce heat which boils water until it turns into steam. The pressurized steam then powers steam turb... ... middle of paper ... ...issions. As we speak the earth is warming and its climates are beginning to change. Polar ice caps are melting causing land to disappear by the day. The amount of greenhouse gases being pumped into the atmosphere by our traditional methods of generating energy is unsightly, and yet we do nothing even when we have the knowledge to end this. If we continue to poison the earth with fossil fuels a global climate change will be inevitable. The effects of that will be catastrophic for every living thing on earth. With zero carbon emissions and the ability to produce electricity on a mass scale, Nuclear Energy is the clean and effective way to continue modern life. Global warming is not a threat of the future, it is happening now. As the main cause of this, humanity must recognize its mistakes, and work to correct them. If we do nothing we will get what we deserve.
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
A. Attention Material: Have you ever thought about energy? Where it comes from and how it powers things? Nuclear energy is one of the many types of energy sources in the world today. It is a non-renewable resource such as coal and natural gas. The first nuclear reactor ever created by man was built in December of 1942. The discovery of building a nuclear power plant was discovered over 150 years ago (Nuclear Power: Villain or Victim?, p. 15).
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
The consequences as the result of the earth warming up cannot be ignored any longer. We need to stop wasting our time debating if climate change is man-made or a natural phenomenon. It is clear to me, and many scientists, that we are slowly killing our planet and all its inhabitants (human and non-human animals). We need to stand united and stand tall in this fight to save the ecosystems. We have become an over populated consumerist society, consuming far more natural resources and energy than the generations before the Industrial Revolution. Thus giving off substantial amounts of greenhouse gases that dramatically change the temperature of our planet. It is well documented in various reports how much the Earth’s temperature is rising and is predicted to rise at a rate of 2°C in the next two to three decades. With two-thirds of the world’s population living within two hundred miles of seacoast, and with most of the world’s economy concentrated in coastal cities, rising sea levels would cause immense devastation. Climate change is happening before our eyes with unpredictable storms and weather patterns, severe droughts, and melting polar caps. It is up to each of us to change our behavior to a more sustainable one, by utilizing renewable energy sources--humankind and the Earth are depending on it (Lovelock
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
The use of nuclear power in the mid-1980s was not a popular idea on account of all the fears that it had presented. The public seemed to have rejected it because of the fear of radiation. The Chernobyl accident in the Soviet Union in April of 1986 reinforced the fears, and gave them an international dimension (Cohen 1). Nevertheless, the public has to come to terms that one of the major requirements for sustaining human progress is an adequate source of energy. The current largest sources of energy are the combustion of coal, oil, and natural gas. Fear of radiation may push nuclear power under the carpet but another fear of the unknown is how costly is this going to be? If we as the public have to overcome the fear of radiation and costly project, we first have to understand the details of nuclear energy. The known is a lot less scary then the unknown. If we could put away all the presumptions we have about this new energy source, then maybe we can understand that this would be a good decision for use in the near future.
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
The warming of the Earth is known more commonly as global warming. Maybe this subject is going to be fought over for centuries while we squander the time we have left, but even if we did stop doing the things that cause global warming, it will not bring it to a standstill. The main cause is pollution, and although scientists say that crude oil will be a thing of the past, alternatives to it will be created. Whether you consider the future to be one hundred years away or just a second, the conception of the future is always the same. There are numerous views on the future, but each one says the identical thing.
In conclusion, global climate change is a very long discussion with many ways to improve the environment, but a long journey to finding a solution. Although we can 't do away with our main sources like power plants, cars, and factories we must continue to find solutions to making our environment safer and suitable to live in. Hopefully in the near future we will have a better understanding of how to address our global climate changes, but for now, we can focus our ideas on preventative ways to not harm ourselves and our
In conclusion, many facts point to global warming being detrimental to our world. With scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations being some of the more thought about topics it`s hard not to agree that our world can not continue to be used as it is. Even with some scientists arguing against the topic, our Earth`s orbit changing the temperatures before and have been through hotter and cooler time periods the pros still outweigh the cons. This is why we, as a global population, need to take into consideration the outcome of our planet should we continue to abuse it the way we do. Our earth and resources are not a right but a privilege and we should learn to treat them as such before we no longer have either.
Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
Because these things will affect society, there are important decisions that have to be made in the present as well as in the future to secure people’s lives and lifestyles. The world community is aware of this serious issue and do already prepare for projects to slow down global warming, but they still have to improve. If the world leaders stop worrying about this issue, the future generations could be in danger. The future lifestyles will be affected by the decisions made in the present day. Society has much to improve to save energy and to lower greenhouse gas emissions.
