Wind and Solar Power Reduce Health Impacts but Increase Mineral Depletion
Shifting to wind and solar power for decarbonization significantly reduces human health impacts but necessitates a greater reliance on mineral resources.
Nature Communications · 2019
Key Findings
- 01All decarbonization pathways result in major environmental co-benefits.
- 02Scenarios prioritizing wind and solar power are more effective in reducing human health impacts compared to those with less renewable energy.
- 03Wind and solar focused pathways lead to a pronounced shift away from fossil fuels towards increased mineral resource depletion.
- 04Non-climate ecosystem damages tend to increase, primarily due to land requirements for bioenergy.
Application
Design takeaway
When designing for renewable energy systems, prioritize technologies that minimize mineral extraction and land use, and consider the full life cycle of materials used.
How to apply
When selecting materials for wind turbines, solar panels, or battery storage, research the mineral supply chains and consider recycled or abundant alternatives. Design energy systems to be as spatially efficient as possible.
Project actions
- 01When researching materials for your design, consider their environmental impact beyond just carbon emissions.
- 02Investigate the sourcing and end-of-life implications of the materials you choose.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Combines two robust modelling approaches (IAM and LCA).
- +Provides a system-level comparison of different decarbonization strategies.
Limitations
It's difficult to get precise data on all the environmental impacts of every material. The future availability of certain minerals is also uncertain.
Reliability & validity
The study's reliability is supported by the use of established modelling techniques. Validity is enhanced by comparing multiple scenarios and considering a range of environmental impacts, though predictions of future impacts inherently involve uncertainty.
Think critically
If wind and solar power increase mineral depletion, what innovative design solutions can be developed to mitigate this specific environmental challenge?
Design Principles
"Prioritize renewable energy technologies that offer the greatest reduction in human health impacts while minimizing adverse effects on mineral resources and ecosystems."
Designers and engineers must consider the full life-cycle environmental footprint of energy systems. While renewable energy sources offer substantial climate and health benefits, their material demands can create new resource challenges that need to be addressed through material selection, circular design principles, and efficient resource utilization.
What This Means for Your Design
Switching to clean energy like wind and solar is good for your health and the planet, but it means we'll need to dig up more metals and minerals. We also need to be careful about how much land we use for things like growing energy crops.

Paragraph starter
The selection of energy technologies for decarbonization presents complex environmental trade-offs. Research indicates that while wind and solar power offer significant reductions in human health impacts, they also lead to increased demand for mineral resources. This necessitates a design approach that critically evaluates material sourcing, promotes resource efficiency, and considers the full life-cycle implications to mitigate potential adverse effects.
