  2. Standby power - Wikipedia

    en.wikipedia.org/wiki/Standby_power

    Standby power used by older devices can be as high as 10–15 W per device, [4] while a modern HD LCD television may use less than 1 W in standby mode. Some appliances use no energy when turned off. Many countries adopting the One Watt Initiative now require new devices to use no more than 1 W starting in 2010 and 0.5 W in 2013.

  3. One Watt Initiative - Wikipedia

    en.wikipedia.org/wiki/One_Watt_Initiative

    The One Watt Initiative is an energy-saving initiative by the International Energy Agency (IEA) to reduce standby power-use by any appliance to no more than one watt in 2010, and 0.5 watts in 2013, which has given rise to regulations in many countries and regions.

    en.wikipedia.org/wiki/Quintessence_(physics)

    Some special cases of quintessence are phantom energy, in which w q < −1, [16] and k-essence (short for kinetic quintessence), which has a non-standard form of kinetic energy. If this type of energy were to exist, it would cause a big rip [ 17 ] in the universe due to the growing energy density of dark energy, which would cause the expansion ...

  9. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4] This is a measurement of average power consumption, meaning the average rate at which energy is transferred ...
