In recent decades‚ the coal consumption among the whole world has sharply increased so as to meet the rapid development in every country. As generating electricity by coal is not renewable and environmental unfriendly‚ people tend to develop renewable energy like nuclear power‚ wind power‚ hydropower etc. though the cost of constructing the plants and utilizing is extremely high. Among the renewable energy mentioned above‚ nuclear power is the most popular to expand. Nuclear power is the use of nuclear

Vietnam is considered to be the most seriously affected by this problem. Carbon dioxide emissions also comes from the burning of the fossil fuels such as oil‚ natural gas and coal for the purpose of electricity generation. The second major cause is methane‚ which is another contributor to the greenhouse effects. Mining for coals and oil releases methane in the atmosphere. Moreover‚ the leakage from natural gas fields and landfills are additional source of methane. When methane exists in the air for
