Their well-being is negatively affected by very low consumption of energy, use of dirty or polluting fuels, and excessive time spent collecting fuel to meet basic needs. Predominant indices for measuring the complex nature of energy poverty include the Energy Development Index (EDI), the Multidimensional Energy Poverty Index (MEPI), and Energy ...
An inverse way of looking at the issue would be an 'economic energy efficiency,' or economic rate of return on its consumption of energy: how many economic units of GDP are produced by the consumption of units of energy. Referring to the above examples, 1 million Btus consumed with an energy intensity of 8,553 produced $116.92 of GDP for the US ...
According to Alan Meier, a staff scientist at the Lawrence Berkeley National Laboratory, standby power before the One Watt Initiative proposals were implemented as regulations accounted for as much as 10% of household power consumption. A study in France found that standby power accounted for 7% of total residential consumption, and other ...
It has attracted considerable attention among energy policy analysts, because its existence suggests that society has forgone cost-effective investments in energy efficiency, even though they could significantly reduce energy consumption at low cost. This term was first "coined" by Eric Hirst and Marilyn Brown in a paper entitled "Closing the ...
The latter includes power that is unusable, so a power factor of 1 is desirable. A low power factor would mean that the electricity supplier would effectively supply more energy than the consumer's bill would indicate, and suppliers are allowed to charge for low power factors. Reactive power is the name given to unusable power. It does no work ...
According to eurostat as of 2021, households represented 27% of final energy consumption in the EU. The main use of energy by households was for heating their homes (64.4% of final energy consumption in the residential sector), with renewables accounting for more than a quarter (27%) of EU households space heating consumption.
Efficiency of power plants, world total, 2008. Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges ...
Low-power broadcasting that the power of the broadcast is less, i.e. the radio waves are not intended to travel as far as from typical transmitters. Low-power communication device, a radio transmitter used in low-power broadcasting. Low-power electronics, the consumption of electric power is deliberately low, e.g. notebook processors.
