The world needs a new source of energy, an unspillable source.

How does a generator work in a geothermal power plant? ?

i know that steam powers the turbine. And depending on the type of plant, i know how the steam is made. But once the turbine is spinning and generating electricity, i get lost. I know it all has something to do with electrons and metal coils and magnetic fields, but can you help me understand it all?
i’ve done bunches of research, but like i said. i just dont understand it. can someone maybe exlain it to me? simply?
