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 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, 1958The 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, 1972Abstract 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.

The dynamics of primary energy substitution
Technological Forecasting and Social Change, 1989Abstract 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 demand in Canada
Energy Economics, 1979Abstract 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 ...

Perhaps we should start by defining what we mean by high energy primary cells. High energy density means different things to different people. Energy density is expressed as the energy per unit volume or the energy per unit weight, and high is a relative term compared to low.
