Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Bad conductor of current, or an insulator.
Let's take an example: gravitational potential energy. An object has more potential energy if it is raised to a higher position. The energy comes from whatever raised it up, although it is also possible (as in the case of meteorites) that the object was never on the ground in the first place.Let's take an example: gravitational potential energy.

Well, the "letting through" of any substance through an object is considered permeability. Therefore, I'd suppose that the rock's ability to let water pass through the voids is called permeability.
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.
Insulation
Thermal insulator
conductor
Conductors let energy (such as electricity and heat) flow through them easily while insulators do not.
It means that you let an electrical current flow. The current will, of course, carry energy.
An opaque object
Insulator.
yes
insulator
Potential (gravitational) energy is transformed into kinetic energy. So, for instance, if you lift an object, you're storing energy which will act on the object once you let it go (increasing velocity).
