Term 2 Week 4 (Weekend Assignment)

Does nuclear energy still have a part to play in the world?

Nuclear power is the use of sustained Nuclear Fission to generate heat and do useful work. Nuclear power provides about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France and Japan together accounting for about 50% of nuclear generated electricity. However, thias source of energy has been controversial since it began and there is still an ongoing debate about its use. The World Nuclear Association and IAEA claim that it is a "sustainable energy sourve that reduces carbon emissions", while Greenspace International and NIRS believe that it poses many threats to people and the environment. From recent news we can see how nuclear accidents have affected the people of Japan. Similarly, in 1986, the Chernobyl disaster has also affected many directly and indirectly.

In my opinion, I think that the pros outweigh the cons, and that humans would continue to use nuclear methods to gain energy. Firstly, like the World Nuclear Association has said, it is an alternative for other unenvironmently-friendly means of energy. In the Chernobyl disaster, even though the reactor was out of control, the Russians could afford to shut it down as it needed energy to keep the town running. As you can see, some parts of the world cannot do without nuclear energy. Also, if you compare the number of people who perished because of nuclear accidents to the number of people who benefitted due to the energy produced, you will find that actually, nuclear energy has more pros than cons. What people can do now is firstly, to enhance security measures to help minimize the impact of an accident, and secondly, to build nuclear plants far away from dense city areas, so in case of an accident, not as much people would be killed.
