The Effects of Embodied Energy
2018Embodied energy is the total amount of energy that was used for the production of a particular good. The chapter describes main principles that are related to this notion, gives the examples of estimation, as well as the examples of application in the energetic balances of biofuel production.

Embodied Energy and Energy Return on Investment
2017Abstract It’s nearly always the case that the energy used to make materials dominates; the energy used in shipping either the raw materials or the finished product is usually small in comparison. For most things that we use, the embodied energy is much less than the energy consumed in operational use.

Briefing: Embodied energy and emissions
Proceedings of the Institution of Civil Engineers - Energy, 2011This paper discusses the concepts of embodied energy and embodied greenhouse gas emissions. It looks at aspects of their development and evaluation, as well as the issues in defining design options and presenting the results of analysis. It is mainly focused on life cycle issues but also on how impacts are valued. It therefore highlights the links and

Rethinking energy efficiency models of cellular networks with embodied energy
IEEE Network, 2011The continuous increase in energy consumption by cellular networks requires rethinking their energy efficiency. Current research indicates that one third of operating energy could be saved by reducing the transmission power of base stations. However, this approach requires the introduction of a range of additional equipment containing more embodied ...

Influence of Embodied Energy in the Energy Efficiency of Optical Transport Networks
39th European Conference and Exhibition on Optical Communication (ECOC 2013), 2013An energy model including both operational and embodied energy is proposed to evaluate the performance evolution of optical transport networks in a multi-period study up to 15 years. Significant improvements in energy efficiency per GHz and energy reductions can be achieved for flexi-grid OFDM-based networks with respect to fixed-grid WDM ones.

L’articolo presenta una descrizione delle due principali metodologie di calcolo dell’embodied energy sottolineandone le rispettive differenze e campi di applicazioni: l’analisi “di processo” come strumento utile per il controllo dei processi industriali di produzione dei materiali, l’analisi “input-output” per il controllo di processi più complessi ...

Environmental impact and embodied energy [PDF]
, 2016 Recent reports from the industry suggest that FRP has been the most cost effective solution at “first installed” cost in a few recent structures. Even if the “first installed’ cost of FRP solutions in not favourable compared to equivalent concrete/steel structures the life cycle cost and life cycle assessment analyses could be used to demonstrate cost ...
