Energy, emissions and environmental impact analysis of wind turbine using life cycle assessment technique

Performance evaluation and life cycle analysis of earth to air heat exchanger in a developing country

“…[3] for the given quantities of heat exchanger materials. The estimation was done for each stage within the boundary system and aggregated to estimate the total GHG emission.…”

“…But till now fossil energy contributing major share on global primary energy consumption whereas the proof reserves are insufficient to fulfill the global energy needs in future. On the other hand, global GHG emission due to combustion of fossil energy is one of the exiting issues, since projected GHG emission would be 70 Gt CO2-eq in 2050, these will make the problems in human living in the world [3]. Immediate mitigation of such emission is emerging now to make better environment for human living.…”

Towards greener horizontal-axis wind turbines: analysis of carbon emissions, energy and costs at the early design stage

“…A study into the energy, emissions and environmental impact of a vertical and a horizontal wind turbine was undertaken by Uddin and Kumar, (2014) and they established that the energy and environmental impact of the vertical-axis wind turbine are 50% more than the impact of a horizontal-axis wind turbine. Lenzen and Munksgaard, (2002) conducted an LCA on a wide variety of wind turbines, focussing on the energy requirements and CO 2 emission.…”

“…In addition to this, inefficiencies in the gearing and power generation components of a wind turbine could reduce the actual conversion efficiency. Common values used for C p are 0.35-0.45 (Uddin and Kumar, 2014;Patel, 2012). In this study 0.4 has been chosen as the power conversion efficiency.…”

Development of a quantitative analysis system for greener and economically sustainable wind farms

“…These can be divided into two main types: vertical axis wind turbines (VAWTs) and horizontal axis wind turbines (HAWTs). VAWT technology is not as well established and they are not commercially viable when compared to HAWTs (Burton et al, 2011) due to their relatively low power rating (Uddin and Kumar, 2014), therefore, this proposed work only considers large HAWTs as used in commercial wind farms. A distinction must be made between onshore and offshore wind farms since they require a different approach for cost, energy and subsequently GHG emission analysis.…”
