Energy Indicator: Primary Energy Intensity

2014
Energy is a material resource that is essential to national economic production and life of urban and rural residents and one lifeline that affects economic and social development as well. However, at the same time, the process of energy exploitation and use may cause many adverse outcomes such as resource exhaustion, ecological damage, and ...

Comparing Primary Energy Attributed to Renewable Energy with Primary Energy Equivalent to Determine Carbon Abatement in a National Context

Journal of Environmental Science and Health, Part A, 2006
The current conventional approach to determining the primary energy associated with non-combustible renewable energy (RE) sources such as wind energy and hydro power is to equate the electricity generated from these sources with the primary energy supply.

Primary Energy/Useful Energy

2014
While the useful energy delivered by an animal, a windmill, or a worker captured most attention in the preindustrial era, the fossil fuel economy of the nineteenth century shifted the focus toward the energy conversion cycle. Only by following the order of transformations and only by measuring just how much was conserved at each stage could the ...

The dynamics of primary energy substitution

Technological Forecasting and Social Change, 1989
Abstract The historical data for world market penetrations of different primary energy sectors over time involves wood, coal, oil, gas and nuclear. An energy-based dynamic systems model of industrial society is developed in this paper, which generates intersubstitution of one energy form for another.

Primary Energy Factors and the primary energy intensity of delivered energy: An overview of possible calculation conventions

Building Services Engineering Research and Technology, 2018
The related concepts of Primary Energy and Primary Energy Factors (which describe how much Primary energy is contained in each unit of delivered energy) are used for international comparisons of national energy use and have become increasingly important regulatory and statistical metrics, especially in relation to the European Energy Performance of ...

On the energy determination of the heavy primaries

Il Nuovo Cimento, 1958
The formula suggested byPeters for the energy determination of the heavy primaries, requires the knowledge of the mean energy of evaporation of the α-particles. The present work establishes that this energy depends slightly from the size of the evaporating nucleus.

On the energy broadening of the primary electrons

Physics Letters A, 1972
Abstract The energy broadening of the primary electron beam in a low pressure discharge was measured using a spherical and a cylindrical probe. The two probes deliver quite different results, the difference being due to the anisotropy of the broadening process.

Primary energy demand in Canada

Energy Economics, 1979
Abstract A regional energy demand model for Canada is described and its properties analysed. The model contains a consistent set of estimated equations that describe the end-use demand for energy within the major consuming regions. A thermal electric submodel is also described which determines the primary energy required to generate thermal ...
