Shades of Green: Life Cycle Assessment of a Novel Small-Scale Vertical Axis Wind Turbine Tree

Are small-scale wind turbines green? In this study, we perform a ‘cradle to grave’ life cycle assessment of novel domestic-scale 10 kW vertical axis turbine tree which uses combined Savonius and H-Darrieus blades. Situated at test site in Surat Thani, Thailand, SimaPro software was used evaluate the environmental impact profile tree. Comparisons Thai grid mix were made, using both with without end-of-life treatments. Impact profiles calculated data collected over two years from higher capacity factor (CF) Chiang Mai, Thailand. Energy greenhouse gas payback times estimated for locations. The relative magnitudes impacts compared prices protocol, investigated reductions three mitigative scenarios: changes design, transportation materials. results showed that Mai had CF = 7.58% Thani 1.68%. A total 9 out 11 less than values but more values. End-of-life treatments reduced by an average 11%. tower generator majority contributors (average 69%). Greenhouse energy 28.61 54.77 years, 6.50 12.50 respectively, only being turbine’s lifetime. Location mitigated most, followed transportation, then We make recommendations further improve
