Nuclear fusion combines nuclei to produce energy and it creates four times as much energy compared to nuclear fission, which is the current form of commercialised nuclear power. In nuclear fusion, it has been tested with reactions of hydrogen isotopes; deuterium and tritium however; it gave off the majority of its energy as radioactive neutrons which is quiet hazardous and raises safety concerns. In contrast, when helium-3 reacts with deuterium it produced low levels of radioactivity and is perfectly safe as it does not give off any pollution or radioactive waste. Therefore, it shows no danger to surrounding areas. By having helium-3 as the next power production on earth it will also decrease the amount of pollution and radioactive waste in the atmosphere.
What happens to the waste? For example, nuclear energy does not produce smoke or carbon dioxide so it does not contribute to air pollution. (Technology Student ,2009) Nuclear power is characterized by the very large amount of energy available from a very small amount of fuel. The amount of waste is also relatively small. However, much of the waste is radioactive and therefore must be carefully managed as hazardous waste.
Since the chemicals they were producing were highly toxic and posed serious threats to human life, Union Carbide could have built the plant in a more isolated area of Bhopal. It was built in Bhopal “because of its central location and access to transport infrastructure” and “was zoned for light industrial and commercial use, not hazardous industry” (Broughton, 2010). They could have continued to operate within the confines that the plant was zoned for, namely non-hazardous industries. However, due to pressure from competition, Union Carbide decided to make the
PROS AND CONS OF NUCLEAR ENERGY While energy from coal, oil and gas are the main source of world’s energy, another of today’s energy source is nuclear power. From the climate change viewpoint nuclear power has certain advantage. Nuclear energy releases nearly no carbon dioxide and therefore does not contribute to global warming. However, nuclear energy does have some tremendous downsides. The prime examples are demonstrated in the catastrophe in Chernobyl and more recently after a 2011 earthquake and tsunami that caused the shutdown of reactors in Fukushima, Japan.
Today, a safer method of making dynamite (and also more common) is combining nitroglycerin, nitrocellulose (a highly flammable material that is made by treating cellulose with nitric acid) and ketone. The chemical equation for nitroglycerin is C3H5(ONO2)3. Dynamite can be made with other products (such as ammonium) but this is less common and can be more dangerous. The overall main explosive reactant within dynamite is the nitroglycerin. When dynamite explodes, it causes an exothermic reaction.
Should Herman Miller use PVC or TPU in its new chair? Justify your answer. Deciding between PVC and TPU, which PVC violated their “Environment for Design” strategy, and TPU, a more expensive and untested sustainable alternative for the chairs arm pads, was a challenge that would impact both deliverables. Both the development and the supply chain team advocated using the PVC material because manufacturing the mirra chair is toxic and is being released. Based on Herman Miller’s historic commitment to innovative environmental processes
Through out her article Cravens highlights the environmental benefits of nuclear energy. While Cravens effectively reaches to her audience and gives credibility to her article, which fortifies her argument, she ultimately diminishes her strength with her failure to completely address some key issues about nuclear energy Through her ethos Cravens’ effective use of ethos gives her the creditability needed for people to listen to what she is saying. She starts off by showing her on credentials for writing this article. She reflects on how, through the research for her book, Power to Save the World: The Truth About Nuclear Energy, she changed her mind from opposing nuclear energy to endorsing it. By giving her readers this information, she is showing that she has done in depth research on the topic of nuclear energy, so they can trust her to give them correct information.
It even generates acid rains, which ultimately kill animals, ruin plants, as well as our own creations. Currently, fossil fuel is in abundance and offers us a valuable service. It is not the fact that we use fossil fuel for the production of energy that renders it usage problematic-The shortcomings are
It comes in many forms such as heat, electricity, light, mechanical energy. Conventional energy sources for instance coal and oil are the main contributors to the global warming. Furthermore, these fossil fuels are not renewable. The good news is alternative sources of energy can replace the current technologies. These renewable energy sources are environmental friendly as they emit less carbon dioxide, compared to fossil fuels.
Recycling Should Be Mandatory Non-biodegradable waste poses a great challenge to environment conservation efforts. This is simply because this kind of waste does not decompose naturally leaving profound effects on the environment. The lack of a proper disposal mechanism puts the world at a poor position in as far as environment conservation is concerned. This calls for government intervention through regulations to revamp the campaign for both the preservation and conservation of Mother Nature. Disposal techniques such as burning and using dumpsites only push the environment further down the drain (Logomasini, 1); since such waste disposal methods bring about environmental concerns as well.
