Primary Energy Factor Electricity

Electricity is a final energy carrier produced from different primary energy sources including fossil energy fuels.

Primary energy factor electricity.

Tper accounts for the energy that is consumed and or lost in transformation transmission and distribution processes. 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. 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. Energy consumption can be expressed as total final consumption tfc or total primary energy requirement tper.

Where primary energy is used to describe fossil fuels the embodied energy of the fuel is available as thermal energy and. It is calculated by applying conversion factors which vary by fuel type to tfc. It indicates how much primary energy is used to generate a unit of electricity or a unit of useable thermal energy. Non renewable primary energy while permitting values that do not have a strictly physical basis.

Primary energy factors for electricity in europe will also be subject to changes as the share of renewables progresses towards 2050 adds to the problem of assessing building performance. 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 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. Primary energy pe is an energy form found in nature that has not been subjected to any human engineered conversion process.

In this respect the methodological choice of the commission is no doubt the most appropriate the alternative being applying a pef of 0. Different national electricity mixes calculation methodologies and a constantly. Projections of the electricity grid mix. A significant portion of uk electricity is now generated using renewable sources like wind and solar energy.

Primary energy factors pef is calculated as the inverse ratio between the amount of delivered energy in say gj and the primary energy required to provide it. Primary energy conversion factors. Thus 1 gj of natural gas delivered to a building may have a pef of for example. What is the primary energy factor.
