Isnt power relating to the speed of a moving force? And Energy the product of Power applied to a system for n seconds?

Power is energy per unit time. So it is transferred the way energy is transferred.

Energy which comes from Heat or Extreme negative temperatures in subatomic astrophysics.
Either way, energy is supplied by these two types of causes.
Yes moving forces can cause power. IE: Machines, however, 2 moving objects colliding together will cause a reaction.
Put this in simular context with fluid flow in a turbine engine. Air flows from the direction of the relative wind into the turbine, it's compressed, and then flows through, to the combustion chamber, which is lit by a fuel valve and igniter, which carries the exhaust out the back, inturn causing a reaction-- that is propulsion greater than where it originally existed.
Heat and/ or heat transfer throughout a given vehicle or machine, causes it to produce power by it's energy formed by a reaction of 2 or more forces or objects.
Chemical reactions do just that. And the basic concept of one and the other coming together may/ or may not affect the energy efficiency.
Sodium by itself is fine, however, when mixed with water, it explodes. Its not so much the understanding of why it is that relates to your question-- its more along the lines of where did the explosion come from.. Simple context explains a chemical reaction, which inturn promoted heat, causing energy, which supplied power to explode..

Power may be transferred mechanically via a rotating or reciprocating shaft or via a gearbox.
It may be transferred via flows of matter eg hot or pressurised material flowing in a pipe
It may be transferred electrically down a conducting wire or cable.
It may be stored by means of chemical or electrochemical reactions for later use.

There are many ways to transfer power..
Mechanically through gears & shafts...
Electrically through wires / power lines..
Heat through water or other conducting materials..
Wirelessly....Microwaves, Lasers etc...
Kinetic energy through falling objects including water..
