Would you consider thought to be energy? I'm thinking its electromagnetic energy.
Energy is the capacity of a physical system to perform work and exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms....
1. mechanical energy
Mechanical energy is energy that results from movement or the location of an object. Mechanical energy is the sum of kinetic energy and potential energy.
Examples: An object possessing mechanical energy has both kinetic and potential energy, although the energy of one of the forms may be equal to zero. A moving car has kinetic energy. If you move the car up a mountain, it has kinetic and potential energy. A book sitting on a table has potential energy.
2. thermal energy
Thermal energy or heat energy reflects the temperature difference between two systems.
Example: A cup of hot coffee has thermal energy. You generate heat and have thermal energy with respect to your environment.
3. nuclear energy
Nuclear energy is energy resulting from changes in the atomic nuclei or from nuclear reactions.
Example: Nuclear fission, nuclear fusion, and nuclear decay are examples of nuclear energy. An atomic detonation or power from a nuclear plant are specific examples of this type of energy.
4. chemical energy
Chemical energy results from chemical reactions between atoms or molecules. There are different types of chemical energy, such as electrochemical energy and chemiluminescence.
Example: A good example of chemical energy is an electrochemical cell or battery.
5. electromagnetic energy
Electromagnetic energy is energy from light or electromagnetic waves.
Example: Any form of light has electromagnetic energy, including parts of the spectrum we can't see. Radio, gamma rays, x-rays, microwaves, and ultraviolet light are some examples of electromagnetic energy.
Depending on how you want to categorize the forms of energy, there are additional types.
6. sonic energy
Sonic energy is the energy of sound waves. Sound waves travel through air or another medium.
7. gravitational energy
Energy associated with gravity involves the attraction between two objects based on their mass. It can serve as a basis for mechanical energy, such as the potential energy of an object placed on a shelf or the kinetic energy of the Moon in orbit around the Earth.

In biology, energy is an attribute of all biological systems from the biosphere to the smallest living organism. Within an organism it is responsible for growth and development of a biological cell or an organelle of a biological organism. Energy is thus often said to be stored by cells in the structures of molecules of substances such as carbohydrates (including sugars), lipids, and proteins, which release energy when reacted with oxygen in respiration.
In human terms, the human equivalent (H-e) (Human energy conversion) indicates, for a given amount of energy expenditure, the relative quantity of energy needed for human metabolism, assuming an average human energy expenditure of 12,500kJ per day and a basal metabolic rate of 80 watts.
For example, if our bodies run (on average) at 80 watts, then a light bulb running at 100 watts is running at 1.25 human equivalents (100 ÷ 80) i.e. 1.25 H-e. For a difficult task of only a few seconds' duration, a person can put out thousands of watts, many times the 746 watts in one official horsepower. For tasks lasting a few minutes, a fit human can generate perhaps 1,000 watts. For an activity that must be sustained for an hour, output drops to around 300; for an activity kept up all day, 150 watts is about the maximum. The human equivalent assists understanding of energy flows in physical and biological systems by expressing energy units in human terms: it provides a “feel” for the use of a given amount of energy.

This may find its way over to PARF but its worth a discussion. I think a few know where I may be going with this...
