What type of energy? Magnetic, Kinetic, Thermal, Light, Nuclear, Red Bull?

It's a meaningless statement. EVERYTHING is energy (or mass, which is a form of energy).

it's like saying "god is existence itself" or "the universe is god" or "reality is god". Well then call it existence, the universe, or reality. Calling it god doesn't add meaning, it muddies the waters. Don't use "god" for things we have perfectly serviceable words for already.

This is an example of a "deepity", an idea or statement that sounds profound, but isn't.

Are we not all energy? If God is energy then he is merely my equal.

I have to admit that I went through that phase for a short period of time in my life. It was hard for me to give up on god. Pantheistic thinking isn't normally harmful but it is as nonsensical as any other religion. I guess when I read "The God Delusion" it erased the last vestiges of that kind of thinking from my mind.

I think people say that because they think that energy can’t be defined or measured. They are ignorant of science. In the same way people use “spirit” or “soul” to describe the human mental and emotional state. They want to mystify things instead of understanding them. Which is annoying !

If God is energy, how many joules is he? What work can be achieved with God? Is God any particular type of energy? (Mechanical, Electric, Magnetic, Gravitational, Chemical, Ionization, Nuclear, Chromodynamic, Elastic, Mechanical wave, Sound wave, Radiant, Rest, or Thermal) Can God be converted from type to type? Can God be converted into mass using E=mc2?

Energy is a construct discovered by physicists to be useful because it is a conserved quantity. Saying "God is Energy" is like saying "God is Angular Momentum". We could just as easily say God is a chair.

Perhaps people use it because they only vaguely understand what Energy actually is and they realize that it is tied in with change of state. "If we can't touch it then maybe it is God."

Also, some may have encountered the Eastern idea of Qi which is often translated in Western terms as "Energy". It is kind of a mistranslated in my understanding.

I just say that it is most likely gas

Calling energy God is like pointing at a truck and saying flamingo. It's not the same thing in the slightest.

I generally just tell them to be happy with their delusion and get on with my life.

...and the "God particle" that the physicists at CERN are looking for would be called that because...

I need a full tank of God in my car?

Ask where to plug in your charger for your phone?

?? If there is a "god" it would be energy, or from a higher dimension, since we can't see it.

People constantly attribute things that happen because of energy to "god" anyway, which is where the idea came from, probably.
Or from being overawed by aliens, as the Sumerian texts allege.
