What is the difference between nuclear fusion and fission?

Nuclear fusion is the opposite to fission. In nuclear fusion, two nuclei of lighter elements combine to create a nucleus of a larger element, whereas in nuclear fission, a nucleus splits into two smaller nuclei. Both release energy, however fusion releases a lot more. Nuclear power uses fission to produce energy. The sun is powered by nuclear fusion.
