Nuclear energy has several advantages according to the document. It produces very low greenhouse gas emissions. It is also a powerful and efficient source of energy that can generate electricity reliably even during poor weather conditions. The fuel for nuclear energy, uranium, has a low cost, which means nuclear energy can provide cheap electricity and has low fuel costs compared to other sources. However, the document also notes several disadvantages, such as radioactive waste that must be disposed of safely, risks of nuclear accidents, production of harmful nuclear radiation and plutonium as byproducts, high initial costs, and potential for major impacts on human life if disasters occur.
