One of the greatest advantages of nuclear power is that it avoids the wide variety of environmental problems arising from burning fossil fuels such as coal, gas and oil. Currently 78% of Australia’s electricity comes from burning coal. Nuclear energy does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Thus ‘global
Amiel Chen Mr. David Fisher World Studies 2 18 May 2011 Should Countries use Nuclear Energy? Nuclear energy is a way to produce energy. “It is basically using the heat that nuclear fission produced to heat up water in order to generate steam. The steam will then turn turbines connected to a generator which will produce electrical power” (Nuclear Power and the Environment). After the earthquake in Japan also known as the Fukushima disaster, the problem of nuclear energy in Japan became the main focus of the world.
Discussion The perception of public towards nuclear power energy has always been negative. Most of them will only look at the negative effects of it and push aside the actual benefits that nuclear has to offer. Actually if we compare nuclear power energy with the other natural sources and also other renewable energy, nuclear is by far the best alternatives so far to replace fossil fuel and oil. Besides its capability of producing a high efficiency power output, it is also the world's largest source of emission-free energy. No controlled air pollutants, such as sulfur and particulates, or greenhouse gases will be produced by nuclear power plants.
In an era where depletion of fossil fuels a major problem and pollution an even bigger issue,it is only the alternate sources of energy which can meet the energy requirements of the future. So today i gaurav grover of class 10-b is here to share my views on the topic alternative sources of energy. Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas.
Finally, the nuclear electromagnetic pulse is made of extremely strong magnetic fields. This pulse disturbs the radio contacts and destroys and electronic devices (“The Atom Bomb – the development of the atomic bomb, the uses of the atomic bomb”). So what all happened to Japan when the first two atomic bombs
Darien Sorensen Professor Potratz English 100 9 October 2009 Rhetorical Analysis on “Better Energy” Gwyneth Cravens addresses the issue of the use of nuclear energy in her article “Better Energy”. She starts off by introducing James Lovelock, who is a prominent figure in the green movement, but four years before she wrote her article, he upset his fans by endorsing the use of nuclear energy. She goes on to explain how the use of nuclear energy will be able to decrease the threat of global warming. She claims that nuclear energy is the only way to get the amount of energy that is needed, without critically hurting the environment. Through out her article Cravens highlights the environmental benefits of nuclear energy.
This whole process is called a nuclear chain reaction. The reactor core generates heat as the kinetic energy is converted to thermal energy. Gamma rays are produced during fission and absorbed by the reactor, where thermal energy is converted to heat. Heat produced by the radioactive decay of fission production remains in the reactor, sometime even if it shut down.
In Ohaake in New Zealand about 320 gm of C02 is produced for each KW hour of electricity produced against 950 to 960 gm. if coal was used. Limitations Geothermal energy is a proven economical resource with energy technology. It has some environmental problems: 1. The steam brings hydrogen sulphide gas to the surface and pollutes the air unless controls are instituted.
To what extent was the nuclear arms race a stabilising factor in the cold war between 1949 and 1963? The nuclear arms race was very much a stabilising factor in the cold war, nuclear weapons were never used in an aggressive way. It was more the fear of each country using nuclear weapons against one another that aided the stabilisation of the cold war. It allowed the cold war to continue to be dormant and lives were not lost as a result of a catastrophic explosion. And with the cold war the likelihood would have been that once one side had launched a nuclear bomb, the other would and the cold war would have turned into a world- wide disaster.
Geothermal energy can create electricity by the same basic method as current power plants. This occurs by drilling into a geothermal reservoir and using the steam power to spin a turbine to create electricity. Geothermal energy can also be used for heating directly without a power plant or using natural gas. It can be used for heating and cooling, food preparation, agriculture, and industrial processes. The one of the most important current benefits of geothermal energy is that it is essentially limitless and is considered clean, producing around one-sixth of the carbon dioxide that a comparative clean natural-gas- power plant produces.
