The rate of growth of human civilization’s global net energy production for the first time in history began to slow down since the end of the twentieth century (King 2015; King et al. 2015a, b). Global net energy production may have already reached, or else is rapidly approaching, a peak as the rate of growth in energy production declines, and as the ...

Shifting from net-zero to net-positive energy buildings
Building Research & Information, 2014Numerous building projects have been presented as having ‘net-zero’ energy performance. Such claims use a variety of different approaches: on- and off-site renewable energy technologies, purchasing green energy credits, etc. Efforts have subsequently been directed at formulating clear definitions of ‘net-zero’ that provide some degree of clarity and ...

Net Kinetic Energy in Littoral Transport
Science, 1971Studies of coastal erosion and coastal management can be put on a firm physical basis only after methods have been developed for closely estimating the energy expended in actual unidirectional net littoral transport of sediment. Such measures have now been obtained for six coastal drift cells. The results, for a 68-year period, vary from a

Net energy as an energy planning tool
Energy Policy, 1987Abstract If energy be considered the physical driving force of a developed or developing economy, a distinction must be made between primary energy sources and the net amount of useful fuel entering the economy. For a given end-use quality, the amount of primary energy required per unit of useful fuel delivered offers a logical allocation mechanism ...

Energy in poultry diets: adjusted AME or net energy
2010Energy evaluation in poultry is generally based on metabolisable energy systems. Since many decades it is questioned whether development of a net energy system would have added value to predict energy partitioning in meat-and egg-producing poultry. Based on the extra-caloric value of fat in laying hens and a potential lower energetic efficiency of ...

Robust net-zero energy buildings
REHVA Journal, 2017The European energy performance of the buildings directive (EPBD) recast states that all new buildings should be nearly zero energy from 2020. Nearly zero energy buildings can be achieved by improving building insulation levels, using energy efficient technologies and integrating renewable energy systems into the built environment. Considering the high
