energy emissions and environmental impact analysis of wind turbine using life cycle assessment technique
Journal of Cleaner Production, 2014Co-Authors: Md Shazib Uddin, S KumarAbstract:Wind turbine used for electricity generation is known as clean and renewable energy technology. The worldwide increasing trend of wind turbine installation present and future projection addressing the issue of energy required for manufacture and environmental impact due to energy consumption. The life cycle energy and environmental impact of wind turbine has been studied in many literature, but some studies are based on average data, the life cycle stages are incomplete of some study, most of the literature are horizontal axis type and the literature for Asian developing countries are rare. In addition, the life cycle study of vertical axis wind turbine is unusual. Since, the life cycle assessment (LCA) study varied from location to location due to industrial performance, countries energy mix and related issues, a life cycle embodied energy, emissions and environmental impacts analysis were undertaken for two grid connected rooftop wind turbines (vertical axis and horizontal axis) considering the industrial performance, applications and related issues in Thailand. The life cycle assessment was done using SimaPro 7.3.3 software from cradle to grave for base case and for alternative cases. The result showed that, wind turbine installation in Thailand at Chiangmai is reliable to deliver wind energy over the year compared to Phuket and Surat Thani Island. The vertical axis wind turbine is energy and emission intensive per kWh/year energy delivered compared to horizontal axis wind turbine for base case system. The embodied energy and environmental impact could be possible to reduce by more than 60% and 50% respectively using Reuse of Materials strategy. The embodied energy of vertical axis wind turbine could be possible to reduce by 36% with thermoplastic and 40% with fiberglass plastic turbine instead of aluminum turbine, while the environmental impact reduction more than 15% has been observed. The energy intensity, CO2 emission intensity and energy payback time found to be lower when compared with literature.

Recycling of Battery Technologies - Ecological Impact Analysis Using Life Cycle Assessment (LCA)
Energy Procedia, 2016Co-Authors: Lea Unterreiner, Verena Jülch, Steffen ReithAbstract:By the means of life cycle assessment (LCA), the ecological impact of recycling and Reuse of Materials of three battery technologies was analyzed: lead acid, lithium-ion and vanadium redox flow. Reuse of Materials is considered through a cradle to cradle method, meaning the Materials which can be Reused count as a credit in the LCA. It is shown that the recycling and Reuse by a good integrated recycling process lower the ecological impact by up to 49%. Some Materials are highly influential. By substitution of these, the ecological impact can be lowered significantly.

life cycle greenhouse gas emissions and energy analysis of prefabricated reusable building modules
Energy and Buildings, 2012Co-Authors: Lu Aye, Tuan Ngo, Robert H Crawford, R Gammampila, Priyan MendisAbstract:Abstract Prefabrication is one strategy considered to provide improved environmental performance for building construction. However, there is an absence of detailed scientific research or case studies dealing with the potential environmental benefits of prefabrication, particularly the embodied energy savings resulting from waste reduction and the improved efficiency of material usage. This paper aims to quantify the embodied energy of modular prefabricated steel and timber multi-residential buildings in order to determine whether this form of construction provides improved environmental performance over conventional concrete construction methods. Furthermore this paper assesses the potential benefits of reusability of Materials, reducing the space required for landfill and need for additional resource requirements. An eight-storey, 3943 m 2 multi-residential building was investigated. It was found that a steel-structured prefabricated system resulted in reduced material consumption of up to 78% by mass compared to conventional concrete construction. However, the prefabricated steel building resulted in a significant increase (∼50%) in embodied energy compared to the concrete building. It was shown that there was significant potential for the Reuse of Materials in the prefabricated steel building, representing up to an 81% saving in embodied energy and 51% Materials saving by mass. This form of construction has the potential to contribute significantly towards improved environmental sustainability in the construction industry.
