The Advantage and Disadvantages of Nuclear Power

many things that can be used as energy sources, ranging from water, wind, solar and geothermal. But, there are sources of energy that became a favorite with developed countries. With low costs and generate greater energy. Is nuclear power. Nuclear power is generated using uranium which is a metal mined in various parts of the world. In the first large-scale nuclear power station opened at Calder Hall in Cumbria, England in 1956.
Some military ships and submarines have nuclear power plants for engines. Nuclear power produces around 11% of the world's energy needs, and produce large amounts of energy. This does not cause pollution as we will get when burning fossil fuels. Benefits of nuclear installations are as follows:
     It costs about coal and fossil fuels are the same, so it is not expansive to make.
     This does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.
     This produces a large amount of energy from small amounts of uranium.
     This produces a small amount of waste and lasting up to 40 years.
     It is reliable.
On the other hand, nuclear power is very dangerous. Small errors that occur can be very damaging, environmental pollution and should be sealed and buried for many years to allow the radioactivity to die away. Furthermore, although reliable, a lot of money to be spent on safety because if it goes wrong,  nuclear accident into a big accident. Examples of disasters that happened was a power plant in Chernobyl ukraine on 26 April 1986, as well as earthquake and tsunami in Japan that resulted in explosion of a nuclear reactor at the Fukushima Daichi.
People are increasingly concerned about this. In a nuclear power source 1990 is the fastest growing in many parts of the world. Being afraid of the threat of radioactive pollution and the abuse that resulted in a nuclear war. This can take quite a bit of casualties in the short and long term.
therefore, we do not need to use energy materials that can cause harmful to humans, environmentally friendly energy can easily be achieved by using natural energy other than fossil fuels, like biogas, solar energy and geothermal energy.
