  2. High tech - Wikipedia

    en.wikipedia.org/wiki/High_tech

    The opposite of high tech is low technology, referring to simple, often traditional or mechanical technology; for example, a slide rule is a low-tech calculating device. [4] [5] [6] When high tech becomes old, it becomes low tech, for example vacuum tube electronics. Further, high tech is related to the concept of mid-tech, that is a balance ...

  3. Efficient energy use - Wikipedia

    en.wikipedia.org/wiki/Efficient_energy_use

    Common energy efficiency label on appliances to indicate their energy efficiency in a clear manner. 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.

  4. Low technology - Wikipedia

    en.wikipedia.org/wiki/Low_technology

    Low technology (low tech; adjective forms: low-technology, low-tech, lo-tech) is simple technology, as opposed to high technology. [1] In addition, low tech is related to the concept of mid-tech, that is a balance between low-tech and high-tech, which combines the efficiency and versatility of high tech with low tech's potential for autonomy ...

  5. Appropriate technology - Wikipedia

    en.wikipedia.org/wiki/Appropriate_technology

    Despite these early examples, Dr. Ernst Friedrich "Fritz" Schumacher is credited as the founder of the appropriate technology movement. A well-known economist, Schumacher worked for the British National Coal Board for more than 20 years, where he blamed the size of the industry's operations for its uncaring response to the harm black-lung disease inflicted on the miners.

  6. Low-energy house - Wikipedia

    en.wikipedia.org/wiki/Low-energy_house

    A low-energy house is characterized by an energy-efficient design and technical features which enable it to provide high living standards and comfort with low energy consumption and carbon emissions. Traditional heating and active cooling systems are absent, or their use is secondary.

  7. Minimum energy performance standard - Wikipedia

    en.wikipedia.org/wiki/Minimum_energy_performance...

    A minimum energy performance standard (MEPS) is a specification, containing a number of performance requirements for an energy-using device, that effectively limits the maximum amount of energy that may be consumed by a product in performing a specified task. An MEPS is usually made mandatory by a government's energy efficiency body.

  8. Power usage effectiveness - Wikipedia

    en.wikipedia.org/wiki/Power_usage_effectiveness

    The PUE metric is the most popular method of calculating energy efficiency. Although it is the most effective in comparison to other metrics, PUE comes with its share of flaws. This is the most frequently used metric for operators, facility technicians, and building architects to determine how energy efficient their data center buildings are. [9]

  9. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle. Energy converter is an example of an energy transformation.
