One of the major challenges in addressing climate change is finding solutions that do not create new problems. While the world needs more solar panels, wind turbines, and transmission lines, building this infrastructure can encroach on critical habitats for endangered animals and indigenous communities. A recent study in the journal Nature Communications revealed that areas suitable for clean energy production overlap with 10% of land important for biodiversity and human needs such as clean water and wood for fuel. This presents a potential conflict between conservation and renewable energy development.
The study, conducted by researchers at Cornell University, mapped the entire world for biodiversity, pressure from farming and development, and “nature’s contributions to people.” It found that only 18% of the land needed by humans is currently protected from urban expansion and resource extraction, with more than one-third suitable for agriculture, mining, oil and gas drilling, or renewable energy projects.
To address this challenge, the study recommends building wind or solar farms on already cleared or degraded land. It also suggests combining renewables with agriculture, such as integrating solar panels with pollinator-friendly flowers and bee hives, or establishing wind farms on cattle ranches. The goal is to carefully plan renewable energy development to avoid undermining conservation and human needs goals.
While the study does not provide a concrete answer regarding the amount of land needed for solar and wind farms, it emphasizes the importance of thoughtful considerations in development. Other research indicates that it is possible to deploy wind and solar energy without significant damage to the environment, and that the environmental consequences of clean energy production are not as dire as continuing to burn fossil fuels.
Ultimately, building renewables without threatening biodiversity requires careful planning and thoughtful considerations. It is possible to achieve conservation, climate, and development goals, but this will necessitate strategic decision-making and innovative approaches to renewable energy development.
