First of all, we need to accept the advantages f nuclear power, as its efficiency is significantly greater than burning fossil fuels. It is estimated that a nuclear power plant can create sufficient electricity to supply a thousand households completely. Furthermore, in the process of generating the power, it emits 10 times less Carbon dioxide than the former technology does. The new energy is an absolutely efficient and clean energy source.
However, there are a lot of concerns about the risks. it is well-known that a tiny portion of radioactive energy can harm human's health. It a nuclear power plant is destroyed by natural disaster, namely an earthquake and Tunami and the radiation leaks out from the plant, the consequences would be catastrophic. Not only are people exposed to the danger directly, but also there are many possibilities that they may intake contaminated foods by accident, because radiation stays in a creature's body and in the food-chain. Therefore, the level of the toxic element is accumulated a high level, which can be harmful to health.
In addition, there are other energy sources and they are much cleaner and less risky. Taking solar energy as an example, with which it is possible to create electric power, thanks to modern technology. while its efficiency is not as high as nuclear energy's, it causes no toxic gases nor substances. It is a truly green energy.
In conclusion, it is true to say that nuclear energy is necessary to provide citizens with comfortable lives, nevertheless, there are a huge number of problems related with health. Thus it is better to have variety of energy sources and develop their technologies rather than by just nuclear power.
