What is your main question as you would now put it?

How the different types of energy interact with space itself. For instance, how does electric energy interact with space?

Physics news on Phys.org
All forms of energy interact with the spacetime curvature tensor per the Einstein field equation. They all contribute to the stress-energy tensor so they are all related to the curvature.
 
I share Nano-Passion's confusion. Yes, energy is the ability to do work. But how is that work actually done. We see work being done by changes in matter. Parameters of matter such as shape, motion, temperture and densisty all change in response to energy. Something as simple a two objects in a collision stops being simple once you ask why does the collision work as it does? The question makes sense to me, however I have no answer.
 
The mechanics of a collisions are very complicated, but that's not because energy is complicated. Any collision beyond assumed ideal objects gets complicated because they deal with complex structures and properties of materials.
