The Sun is a self-sustaining fusion plasma that already exists. It is confined by its own gravity. It will continue running at a steady state for billions of years. Except for melanomas, this source of power is completely harmless to human life.
In order to plug this thing into the electric grid, all we need to do is capture the free electromagnetic emissions of the Sun. We already have this technology, called a photovoltaic cell. The production of such cells is an industrial engineering problem. There are no technological barriers.
Compare to "fusion power", for which the ignition, confinement, and exploitation of the energy are all totally unsolved technological problems.
