Climate change & energy crisis: Is it time to reconsider nuclear energy?
In the 21st century, human kind is struggling to escape a self-created double edged blade, which is getting sharper with each day. It’s the blade of catastrophe, the duo of energy crisis and climate change. The world needs energy and it’s getting it but at a great cost. Burning fossil fuels supplied the major part. While the present emission levels strictly prohibit anymore burning to avoid irreversible damages of ‘climate change’, the energy requirement of the world is rising simultaneously, asking to burn every bit of it or anything that could produce energy. Because, now the world can’t do without it.
Renewable energy resources look the greenest option, but presently, available technologies can’t make best of it to supply energy good enough to replace fossil fuels. The present technologies used in the development of photovoltaic, wind turbines, hydro-turbines, bio-fuels, fuel cell etc. are still developing and aren’t efficient enough to fill the gap. On the other hand, the battery technologies are struggling for larger storage capacities. In a way, both the production and storage of the energy produced through renewable sources of energy aren’t in position to put the world completely off the traditional grid. It’ll take years, but it might be too late at that point of time. What we need is an immediate replacement with zero-emission. Presently, there is only one solution, which is most promising, but comes with great hazards and criticism. It’s the irony of present civilization that nuclear power is the best option, but isn’t completely safe. Chernobyl and Fukushima disasters have already demonstrated the horrors of nuclear radiations.
But, as a matter of fact, nuclear power is the world’s largest source of emission-free energy. Nuclear power plants produce no air pollutants, such as sulfur and particulates, or greenhouse gases. The use of nuclear power in place of other energy sources helps to keep the air clean, preserve the Earth’s climate, avoid ground-level ozone formation and prevent acid rain. Nuclear power has important implications for our national security. Inexpensive nuclear power, in combination with fuel cell technology, could significantly reduce our dependency on foreign oil.
Recently, in November 2013, an open letter from renowned climate and energy scientists again flared the debate on the use of nuclear power to tackle both energy crisis and climate change. These four climate experts included James Hansen, former NASA scientist-turned-activist, Ken Caldeira of the Carnegie Institution for Science, climatologist Tom Wigley, and Kerry Emanuel of MIT. The letter proposed development and deployment of “safer nuclear energy systems.” They laid emphasis on reconsidering the use of nuclear power in light of the newer, safer technologies like ‘Fast Reactor’. The four of the best experts admit that presently it’s not possible to save the world through any single source. The world need a mix of energy and nuclear power is the best candidate in their view. So, now, it’s time to ask the same old question about testing of nuclear power. Is right or wrong to start testing nuclear energy with newer technologies or not? Should governments refrain from using nuclear energy in a time when countries like France, China, an Korea have managed to squeeze the same source efficiently along with reducing a great lot of emissions?
Much controversy has already emanated regarding the issue of nuclear power. As time draws on, many people are concerned that at some point the world oil supply will vanish and we will have to compensate for its loss by using an alternative power source. Some people predict that this event will occur early in the twenty first century and for this reason, the question has been raised about what alternative power source we will use. Nuclear power seems to be a popular choice with many people, and many people believe that nuclear power is inexpensive and creates no air pollution.
However, while this may be true, it is also evident that the radioactivity released during accidents at nuclear power plants has caused many deaths and environmental damage. Thus, a number of people are opposed to nuclear power; execrate the use of nuclear power, its use in our society and at the Western Nuclear Power Industry in particular. In my opinion, nuclear power should be banned and there are many risks taken when nuclear power is used. For one thing, there is always the risk that a meltdown or reactor leakage could occur.
Furthermore, there are also problems in storing waste from nuclear reactors, the issue of thermal pollution and concerns about worker safety and security. There is the possibility that nuclear reactors will experience a ‘melt down’ where the cooling systems fail and nuclear fuel reaches such a temperature, that it melts away through the reactor or causes damage to reactor walls. This allows the spread of radioactivity, a lethal thing, which can not only pollute the environment but cause cancers and sickness to occur within humans.
Besides from a ‘melt down’ causing the spread of radioactivity, there is also the fear that radioactive wastes from reactors will escape into the environment and contaminate it with radioactivity. Radioactivity is definitely not an issue to be taken lightly. Radiation also had a disastrous effect on many children, with deformations such as “club feet”, “hair lips”, oversized skulls and missing body parts occurring, and there are such cases in India near the nuclear power stations.
Apart from the serious health problems, the environment also suffered with fish being poisoned and other animals dying. Perhaps the worst thing about radiation is that it doesn’t disappear within a short time. In fact, it is known that radiation can remain within the soil for up to a million years, and still have an effect upon animals and humans.
Imagine the risks radiation could pose if it happened to leak out and spread over our community. It would be such a disaster; simply unimaginable to some people. We can’t put ourselves, and yet alone our children at risk to this hideous substance.
In the future, the world might succeed in developing advance and safer nuclear power plants, and may be, we will gain access to the abundant pool of nuclear energy, but till then, what we need to worry about is the energy wastage and emissions. Presently, the solution lies in using combination of all available alternative sources, and somehow cut the consumption of fossil fuels. After all, the energy crisis and climate change are nearer than they appear.
