Primary energy conversion factors.
Primary energy factor electricity.
Energy consumption can be expressed as total final consumption tfc or total primary energy requirement tper.
Regarding the primary energy factor applied to electricity from non combustible renewable sources for electricity pv wind and hydro the choice to apply a pef 1 is already quite generous7.
It indicates how much primary energy is used to generate a unit of electricity or a unit of useable thermal energy.
Primary energy pe is an energy form found in nature that has not been subjected to any human engineered conversion process.
A primary energy factor p ef connects primary and final energy.
Different national electricity mixes calculation methodologies and a constantly.
It is energy contained in raw fuels and other forms of energy received as input to a system primary energy can be non renewable or renewable.
In this respect the methodological choice of the commission is no doubt the most appropriate the alternative being applying a pef of 0.
Projections of the electricity grid mix.
It is calculated by applying conversion factors which vary by fuel type to tfc.
Only generation is considered the primary energy factor of electricity can be calculated by dividing the raw primary energy demand of electricity generation by the electricity produced.
Electricity is a final energy carrier produced from different primary energy sources including fossil energy fuels.
Having found the primary energy factors for the fuels that are used in the production of electricity a weighted average using these projections gives the primary energy factor for electricity.
Where primary energy is used to describe fossil fuels the embodied energy of the fuel is available as thermal energy and.
Thus 1 gj of natural gas delivered to a building may have a pef of for example.
A significant portion of uk electricity is now generated using renewable sources like wind and solar energy.
However system boundaries could be expanded to also include transmission and distribution losses or energy used to extract clean and transport the fuels.
Tper accounts for the energy that is consumed and or lost in transformation transmission and distribution processes.
What is the primary energy factor.
Iinas 5 pef of eu 28 electricity development of primary energy factors of el ectricity generation in the eu 28 from 2010 2013 2 2 results for the primary energy factors in the eu 28 using the refined gemis database the results for the primary energy factor pef were calculated and are given in the following table.
