Embodied energy is the energy consumed in all activities necessary to support a process in its entire lifecycle. For power generation systems, this includes the energy cost of raw material extraction, plant construction, operation and maintenance, and recycling and disposal. Embodied energy analysis is a crude method of estimating the environmental impacts and depletion of natural resources consequent to a certain process. In effect, the higher the embodied energy of a process, the greater the green house gas emissions and the depletion of natural resources. This paper presents the embodied energy analysis carried out on some New Zealand power plants belonging to various methods of generation. The analysis follows the standards set out by the International Organisation for Standardisation 14040 series, and uses some guidelines given in the International Federation of Institutes for Advanced Study workshop on energy analysis methodology and conventions. It was found that the lifecycle performance, in terms of energy payback, of renewable electricity generation is superior to nonrenewable electricity generation. From the generation methodologies, hydro power plants have exceptional performance characteristics.

Abstract:To explore the differences in carbon emissions over the whole life-cycle of different building structures, the published calculated carbon emissions from residential buildings in China and abroad were normalized. Embodied carbon emission flows, operations stage carbon emission flows, demolition and reclamation stage carbon emission flows and total life-cycle carbon emission flows from concrete, steel, and wood structures were obtained. This study is based on the theory of the social cost of carbon, with an adequately demonstrated social cost of carbon and social discount rate. Taking into consideration both static and dynamic situations and using a social discount rate of 3.5%, the total life-cycle carbon emission flows, absolute carbon emission and building carbon costs were calculated and assessed. The results indicated that concrete structures had the highest embodied carbon emission flows and negative carbon emission flows in the waste and reclamation stage. Wood structures that started the life-cycle with stored carbon had the lowest carbon emission flows in the operations stage and relatively high negative carbon emission flows in the reclamation stage. Wood structures present the smallest carbon footprints for residential buildings.

“…Different methods of evaluating the energy performance of buildings have been identified and employed by different researchers. [3] applied a hybrid method in the energy analysis of building materials. They identified three types of energy analysis methods: (1) statistical analysis, (2) input-output analysis, and (3) process analysis.…”
