SIMPLY put; (excerpt and disected from ENCYCLOPEDIA OF PHYSICS)

ENERGY is the ability to produce work. It is a certain abstract scalar
quantity that an object is said to possess. It is NOT something that is
directly observable.
Some say it is a process of gravity.
WORK is the transference of energy from one object to another by a force
from one on the other when that second object is displaced by the force.
FORCE is the release of energy to another object.

As clear as the Mississippi River now huh?

Thank you Chris and Martin,

which brings me to the question, what exactly is energy? I am trying to put
aside what I have learned about it and look at it with a second naivety. I
find it hard to grasp (similar to the idea of gravity).

But perhaps this is not so interesting for others. I've been trying to
re-think basic concepts lately, everything I think I know, and when thinking
about it I realize that I don't.

But back to the topic: Reading your explanations the accelerated tree growth
in the Tunguska area would therefore simply be a stress symptom?
