| Use advice for data set | Users of this LCA data should focus on the complete life cycle of the wind turbines, which includes production, transportation and installation, power generation, maintenance, and end-of-life stages. Attention must be given to the consumption of raw materials and fossil fuels, as well as the emissions related to the production and operation of the wind turbines. When evaluating the environmental and economic impacts, it is imperative to consider system boundaries and the methodologies introduced for impact assessment, ensuring the use of a consistent functional unit (kWh of electricity). Moreover, users should acknowledge the source and method of deriving cost data, as well as the context provided by the specific regional wind farm operational details for accurate LCA results. |
| Technical purpose of product or process | The process described is the manufacturing of rotors for 1.25 MW wind turbines, specifically designed for a wind power system. This system is utilized to generate renewable energy through wind power, which is a critical component within large-scale wind farms. The rotors are part of an environmentally sustainable solution for electricity generation, aimed at replacing or supplementing traditional fossil fuel-based power plants. |

| Deviations from LCI method approaches / explanations | According to Introduced by the life cycle assessment approach [34,35], firstly the system boundaries boundary of wind energy as well as and thermal power are first identified. Then, methodology on evaluating both environmental and economic benefits is presented so that co-benefits can be quantified followed by the introduction of the methodologies on environmental as well as economic impacts evaluation from the co-benefits perspective. | ||||

| Data selection and combination principles | This wind farm is equipped with 24 wind turbines, with a production capacity of 1.25 MW for each turbine, and t the operation life for each turbine is expected to be 20 years. The life cycle of one wind power system can be divided into five stages, including (1) production, (2) transportation and installation, (3) power generation, (4) maintenance, and (5) end-of-life recycling and disposal. The input of non-renewable energy has been shown in each stage. In this study, raw material, fossil fuel consumption and corresponding emissions have been taken into account of a life cycle process. Meanwhile, cost-effectiveness of a wind farm is considered because the cost plays a very important role in operating a wind farm [38]. Considering the data reliability and availability, the cost data of this wind farm was mainly extracted from a feasibility report of one wind farm (with a designed capacity of the 49.5 MW) in Kang ping County of Liaoning province [39]. | ||||
