| Use advice for data set | Users should apply this LCA data for evaluating the environmental impacts associated with the construction of wind farms based on the inclusion of materials and processes described. It is imperative that users adhere to ISO 14040 and ISO 14044 standards to assess the GHG emissions over the full life cycle of wind turbines when utilizing this data. Caution should be taken to ensure representativeness of the data when extrapolating to different geographical locations or technological contexts. It is also advisable to consider potential methodological changes over time and updates in emission factors from newer databases or future surveys. |
| Technical purpose of product or process | The major engineering construction data set for a 40 MW wind farm represents the use of 20 2MW wind turbines in an onshore setting, specifically in North China. The construction includes the types and quantities of materials that are typically used for the development of wind farms in China. This data is relevant for stakeholders in the renewable energy sector, such as wind farm project developers, environmental consultants, and policy makers, for planning and evaluating new wind farm projects and for expanding the use of wind power in sustainable energy portfolios. |
