Application

Design takeaway

When developing new wind turbine technologies, prioritize design choices that minimize environmental impacts across the entire product life cycle, not just operational efficiency.

How to apply

Before finalizing a new wind turbine design, conduct a comprehensive LCA to identify and mitigate potential negative environmental impacts associated with material choices, manufacturing processes, and structural modifications.

Project actions

  • 01When researching new materials or designs for your project, look for studies that assess their environmental impact over their entire life.
  • 02Consider the trade-offs: does a more efficient design use rarer materials or require more energy to produce?

Strengths & Limitations

Strengths

  • +Provides a comparative analysis of multiple design variations.
  • +Focuses on a relevant renewable energy technology.

Limitations

It can be difficult to get precise data for the environmental impact of new, unproven technologies.

Reliability & validity

The reliability of the LCA depends on the accuracy of the input data for material properties, manufacturing processes, and energy consumption. Validity is enhanced by the comparative nature of the study, focusing on relative differences between design options.

Think critically

If a new design significantly improves energy generation efficiency but also increases the use of rare earth minerals or has a higher carbon footprint during manufacturing, is it truly a sustainable improvement?
