Nuclear energy is good energy compare to the petroleum, but the causes of the nuclear energy is painful. There are accidents happened in the past. Radioactive wastes might affect our next generation as well as creates a target for terrorism. The cooling systems of nuclear reactors might change the temperature of seas, rivers, or lakes, then it will affect the creature lives in the seas, rivers, or lakes. However, we have many renewable energies that could provide enough power in our daily life if we have enough funding or policies to promote the renewable energies, such as solar, wind, geothermal and so on.
