Definitions of energy on the Web:
(physics) the capacity of a physical system to do work the units of energy are joules or ergs "energy can
take a wide variety of forms"
forceful exertion "he plays tennis with great energy" "he's full of zip"
enterprising or ambitious drive "Europeans often laugh at American energy"
an imaginative lively style (especially style of writing) "his writing conveys great energy" "a remarkable
muscularity of style"
a healthy capacity for vigorous activity "jogging works off my excess energy" "he seemed full of vim and
Department of Energy: the federal department responsible for maintaining a national energy policy of the
United States created in 1977
Energy is a fundamental quantity that every physical system possesses it allows us to predict how much
work the system could be made to do, or how much heat it can produce or absorb. In the past, energy was
discussed in terms of easily observable effects it has on the properties of objects or changes in state of
various systems. Basically, if something changes, some sort of energy was involved in that change. ...
Energy is a 1988 album by the punk band Operation Ivy.
Energy is a term used by humans to describe intangible, but perceptible, variations in emotional and
physical stamina and motivation.
The capacity for doing work. Forms of energy include thermal, mechanical, electrical, and chemical.
Energy may be transformed from one form into another.
The ability to do work. People get energy from food. Your toaster and your washing machine get their
energy from electricity.
the capacity for doing work.
The capacity for doing work as measured by the capability of doing work (potential energy) or the
conversion of this capability to motion (kinetic energy). Energy has several forms, some of which are easily
convertible and can be changed to another form useful for work. Most of the world's convertible energy
comes from fossil fuels that are burned to produce heat that is then used as a transfer medium to
mechanical or other means in order to accomplish tasks. ...
is the property something has that enables it to do work. The unit of energy is the joule (J). The basic
forms of energy are kinetic energy, potential energy, and rest energy. The law of conservation of energy
states that energy can be neither created nor destroyed, although it may change from one form to another
(including mass).
The capacity to do work.
A property of a body related to its ability to move a force through a distance opposite the force's direction
energy is the product of the magnitude of the force times the distance. Energy may take several forms:
see kinetic energy, potential energy, and elastic energy.
a biological resource used to control the environment. analog: tension.
the ability to do work

Here's a taster:

The fundamental substance of everything in the universe. The nonphysical factors of our lives are energetic
in nature. Energy is characterized by vibration and the impulse to move.
A measure of being able to do work. There are many forms of energy, such as heat, mechanical, electrical,
radiant, chemical, and nuclear energies. Energy is measured in such units as the joule (J), erg,
kilowatthour (kWhr), kilocalorie (kcal), footpound (ftlb.), electronvolt (ev), and British thermal unit (BTU).…read more
