Reply #57: This is Thermodynamics - not lawl

[DrGregory]

An energy carrier is a substance or phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes (ISO 13600).

========================================

Who cares what some "standards" agency defines
as energy, or energy carrier, or WHATEVER.

This is PHYSICS - not legalese.

In PHYSICS, electric energy, mechanical energy,
are "work" - they are energy with ZERO entropy.

Heat on the other hand contains entropy.

Higher temperature heat contains less entropy
for the same amount of heat energy as does lower
temperature heat.

Fuels store potential energy; usually of chemical
type. When the fuel is burned; we get heat AND
entropy.

We should be basing our energy discussion on
PHYSICS - not legalese. The reason is that there
is no penalty for violating the Laws of Physics -
the Universe just doesn't allow you to do it.

That can't be said for man-made laws.
