How does mechanical energy (primarily steam/wind powered turbine ) become electrical energy and vice versa.

Imagine that you have a big wheel. You can spin this wheel to add energy to it. If you have a wheel thst spins, you can take energy from it. This is used in machines to store kinetic energy. It is even used to store energy as a battery by accelerating it with a motor, and the slowing it down with that motor and you get energy from it.
So from this we know that we know that we can turn energy in to movement and movement in to energy. Electricity is just a means to transfer energy.
We know that when electrons moves through a conductor it makes a magnetic field, and if we move a magnetic field through a conductor we can move electrons. Just like we can spin a wheel to add energy to it, we can take a wheel that spins and get energy from it.
Energy is just gradient of potential, whether it is movement, heat, electricity or pressure. We can heat a thing, and then have that later warm something that is cold. We can pump air to a tank and have that power something with flow of pressurised air. We can spin a wheel and slow a wheel down. And we can move electrons to get magnetic field and we can move a magnetic field to move electrons.
At the fundamental level all energy is movement. Heat is movement of atoms, electricity is movement of electricity, kinetic energy is movement of mass.
