  2. Electrical efficiency - Wikipedia

    en.wikipedia.org/wiki/Electrical_efficiency

    Electric kettle: more than 90% [citation needed] (comparatively little heat energy is lost during the 2 to 3 minutes a kettle takes to boil water). A premium efficiency electric motor: more than 90% (see Main Article: Premium efficiency). A large power transformer used in the electrical grid may have efficiency of more than 99%. Early 19th ...

  3. Energy (psychological) - Wikipedia

    en.wikipedia.org/wiki/Energy_(psychological)

    He argues that this intensity, can be understood separately from emotion and that this intensity might be considered energy. [7]: 54 However, a significant volume of empirical research on energy psychology has emerged over several decades, much of it published in peer-reviewed medical and psychology journals.

  4. Neural efficiency hypothesis - Wikipedia

    en.wikipedia.org/wiki/Neural_Efficiency_Hypothesis

    In a study, it was found that the hypothesis only holds for easy tasks. For difficult tasks, intelligent individuals may show increased brain activation. The study revealed that participants with high IQ showed weaker activation during easy tasks but had a significant increase from easy to difficult tasks.

  5. Electromagnetic theories of consciousness - Wikipedia

    More recently, their ideas have been elaborated by Mari Jibu and Kunio Yasue. Water comprises 70% of the brain, and quantum brain dynamics (QBD) proposes that the electric dipoles of the water molecules constitute a quantum field, referred to as the cortical field, with corticons as the quanta of the field. This cortical field is postulated to ...

  6. Maximum power principle - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_principle

    Like the maximum power theorem, Odum's statement of the maximum power principle relies on the notion of 'matching', such that high-quality energy maximizes power by matching and amplifying energy (1994, pp. 262, 541): "in surviving designs a matching of high-quality energy with larger amounts of low-quality energy is likely to occur" (1994, p ...

  7. Rebound effect (conservation) - Wikipedia

    en.wikipedia.org/wiki/Rebound_effect_(conservation)

    Technological improvements in energy efficiency may result in a small take-back. However, even in the long term, energy efficiency improvements usually result in large overall energy savings. Even though many studies have been undertaken in this area, neither position has yet claimed a consensus view in the academic literature.

  8. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Advertising with high energy and light pollution in Shinjuku, Japan. Since the 1973 oil crisis, energy conservation has been an issue in Japan. All oil-based fuel is imported, so domestic sustainable energy is being developed. The Energy Conservation Center [50] promotes energy efficiency in every aspect of Japan. Public entities are ...

  9. Efficient energy use - Wikipedia

    en.wikipedia.org/wiki/Efficient_energy_use

    Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.
