Wind turbine manufactue ; 2 MW wind turbine (20)
Use advice for data set Users of this LCA data set should ensure the proper application of process-based lifecycle assessment methodologies, adhering to the standards outlined in ISO 14040 and ISO 14044. Attention must be given to the average input material types and quantities as representative for current Chinese wind farms, using the specific data points provided for accurate impact assessment. GHG emission factors must be sourced from reliable databases such as GaBi for applicability and consistency. It is important to define the functional unit properly as the wind turbine's ability to supply 2 MW power to ensure comparability and relevance in LCA studies.
Technical purpose of product or process The manufacturing process described pertains to the assembly of wind turbines specifically designed for large-scale wind farms. This process involves the production of 20 units of 2 MW wind turbines, suitable for deployment in an onshore 40 MW wind farm. The technical usage of these turbines is for the generation of renewable energy by harnessing wind power, supplying electricity to the grid, and contributing to sustainable development goals.
