The dynamo and the central power station brought the electric motor into action. The dynamo and the motor do precisely opposite things. The dynamo converts mechanical energy into electric energy. The motor transforms electric energy into mechanical energy. But the two work in partnership and without the dynamo to manufacture the power the motor could not thrive. Moreover, the central station was needed to distribute the power for transportation as well as for lighting.英文原著 · 《The Age of Invention》
Is the contribution of the brain to the production of heat due to the conversion of latent energy directly into heat, or does the brain produce heat principally by converting its latent energy into electricity or some similar form of transmissible energy which, through nerve connections, stimulates other organs and tissues, which in turn convert their stores of latent energy into heat?英文原著 · 《The Origin and Nature of Emotions》
But if we imagine the system rapidly to rotate, the centrifugal force would enable the six corpuscles to remain in a single ring. Thus internal kinetic energy would maintain a configuration which would become unstable as the energy drained away. Now in a system of electrons, electromagnetic radiation would result in a loss of energy, and at one point of instability we might well have a sudden spontaneous redistribution of the constituents, taking place with an explosive violence, and accompanied by the ejection of a corpuscle as a beta-ray, or of a large fragment of the atom as an alpha-ray.英文原著 · 《Darwin and Modern Science》
In fever, then, we have diminished intake of energy, but an increased output of energy--hence the available potential energy in the body is rapidly consumed. This may be an adaptation for the purpose of breaking up the foreign protein molecules composing the bacteria. Thus the body may be purified by a chemical combustion so furious that frequently the host itself is destroyed. The problems of immunity are not considered here.英文原著 · 《The Origin and Nature of Emotions》
As to the mechanism which produces fever, we postulate that it is the same mechanism as that which produces muscular activity. Muscular activity is produced by the conversion of latent energy into motion, and fever is produced largely in the muscles by the conversion of latent energy into heat. We should, therefore, find similar changes in the brain, the adrenals, the thyroid, and the liver, whatever may be the purpose of the conversion of energy-- whether for running, for fighting, for the expression of emotion, or for combating infection.英文原著 · 《The Origin and Nature of Emotions》

What I'm doing is I'm transferring my positive energy into Cameron, and I'm taking out all the negative energy.美剧 · 《Modern Family》

So, the same energy that's gonna be used to reactivate the machine, could that energy somehow be used to reactivate Optimus电影 · 《Transformers (2011)》
It's never a competition. But there's this other energy sometimes that I see going on that just makes me insane, you know.电影 · 《20 Feet From Stardom (2013)》
