  3. Electricity pricing - Wikipedia

    en.wikipedia.org/wiki/Electricity_pricing

    The power factor is the ratio of real to apparent power in a power system. Drawing more current results in a lower power factor. Larger currents require costlier infrastructure to minimize power loss, so consumers with low power factors get charged a higher electricity rate by their utility. [23]

  4. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

  5. Power factor - Wikipedia

    en.wikipedia.org/wiki/Power_factor

    Individual electrical customers who are charged by their utility for low power factor may install correction equipment to increase their power factor to reduce costs. Power factor correction brings the power factor of an AC power circuit closer to 1 by supplying or absorbing reactive power, adding capacitors or inductors that act to cancel the ...

  6. Performance per watt - Wikipedia

    en.wikipedia.org/wiki/Performance_per_watt

    System designers building parallel computers, such as Google's hardware, pick CPUs based on their performance per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. [2] Spaceflight computers have hard limits on the maximum power available and also have hard requirements on minimum real-time performance.

    Currently, the USCF uses a formula that calculates the K-factor based on factors including the number of games played and the player's rating. The K-factor is also reduced for high rated players if the event has shorter time controls. [16] FIDE uses the following ranges: [31]

  8. Chess piece relative value - Wikipedia

    en.wikipedia.org/wiki/Chess_piece_relative_value

    Edward Lasker stated that "It is difficult to compare the relative value of different pieces, as so much depends on the peculiarities of the position". Nevertheless, he valued the bishop and knight ( minor pieces ) equally, [ 16 ] the rook a minor piece plus one or two pawns, and the queen three minor pieces or two rooks. [ 17 ]
