The nuclear power plants which supply most of our electricity work by nuclear fission, splitting atoms and releasing energy. But they also release radioactivity and create dangerous waste materials.
The sun works by nuclear fusion, forcing atoms together to create new atoms and energy. The fuel needed is much more easily obtained and the process is clean and non polluting.
There’s a detailed article on Wikipedia about nuclear fusion that explains it very well.
An article on the ITER website lists the advantages: Abundant energy, sustainability, no CO2, no long-lived radioactive waste, limited risk of proliferation, no risk of meltdown, and cost.

The book A Brief History of the Future predicts that we achieve nuclear fission by 2155 and it leads to the end of alternative energy, like wind and wave turbines and solar power. The British experiment hope to have a working plant by 2040.
