You can use the electricity to pump water up into a high reservoir, where it then has mechanical potential energy. Or store it in a battery - chemical potential energy.
It can be both, potential energy whilst in store, but kinetic energy when put to practical use.
True. Potential energy is energy that is stored or is a available for use by body.

there is lot of potential energy in sun. We are not using it full.
True, in the case of coal it is potential chemical energy
Well anywhere
