1. The impetus behind all motion and all activity.

   “A “moving platform” scheme[…]is more technologically ambitious than maglev trains even though it relies on conventional rails.[…]This set-up solves several problems […]. Stopping high-speed trains wastes energy and time, so why not simply slow them down enough for a moving platform to pull alongside?”

2. The capacity to do work.

   “There is an hour or two, after the passengers have embarked, which is disquieting and fussy.[…]Stewards, carrying cabin trunks, swarm in the corridors. Passengers wander restlessly about or hurry, with futile energy, from place to place.”

   “McGrath, the manager of Somewhere/Else, told GCN that the long hours she has put in since she has become the bar's manager have left her drained of the energy required to undertake a rebuilding effort.”

3. A quantity that denotes the ability to do work and is measured in a unit dimensioned in mass × distance²/time² (ML²/T²) or the equivalent.

   “Negative feelings can be worked through and their energy converted into positive energy[…]. In crisis, normal patterns of self-organization fail, resulting in anxiety (negative energy). Being open systems, people can exchange this energy with the environment and create positive energy for taking action based on a reorganisation of self as necessary to resolve the crisis and emerge at a higher level of consciousness; that is, until the next crisis.”

5. The external actions and influences resulting from an entity’s internal nature (ousia) and by which it is made manifest, as opposed to that internal nature itself; the aspect of an entity that can affect the wider world and be apprehended by other beings.

For He possesses on the one hand, as God and being of like essence with the Father, the divine energy, and, likewise, since He became man and of like essence to us, the energy proper to human nature. […] Energy is the efficient and essential activity of nature; the capacity for energy is the nature from which proceeds energy; the product of energy is that which is effected by energy; and the agent of energy is the person or subsistence which uses the energy.”
