  2. Voltage reduction - Wikipedia

    en.wikipedia.org/wiki/Voltage_reduction

    Either purchase power from another utility, usually at substantial prices, or reduce demand. Often utilities use load management systems to turn off customers' air conditioners, water heaters, and pool pumps to reduce demand. Voltage reduction has become another option for utilities to reduce demand—typically unbeknownst to the customer.

  3. 2021 Texas power crisis - Wikipedia

    en.wikipedia.org/wiki/2021_Texas_power_crisis

    In February 2021, the state of Texas suffered a major power crisis, which came about during three severe winter storms sweeping across the United States on February 10–11, [6] 13–17, [7] and 15–20. The storms triggered the worst energy infrastructure failure in Texas state history, leading to shortages of water, food, and heat. [8]

  4. Noise reduction coefficient - Wikipedia

    en.wikipedia.org/wiki/Noise_reduction_coefficient

    A reverberation chamber is used to test the sound absorption coefficients and NRC of a material. The noise reduction coefficient (commonly abbreviated NRC) is a single number value ranging from 0.0 to 1.0 that describes the average sound absorption performance of a material. An NRC of 0.0 indicates the object does not attenuate mid-frequency ...

    Hybrid Sankey diagram of 2011 U.S. interconnected water and energy flows. The water-energy nexus is the relationship between the water used for energy production, [1] including both electricity and sources of fuel such as oil and natural gas, and the energy consumed to extract, purify, deliver, heat/cool, treat and dispose of water (and wastewater) sometimes referred to as the energy intensity ...

  7. Diffusion (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Diffusion_(acoustics)

    Diffusion, in architectural acoustics, is the spreading of sound energy evenly in a given environment. A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position. Most interior spaces are non-diffusive; the reverberation time is considerably different around the room.
