Protecting habitats when planning clean energy would cost about 3% more
In models of 11 western U.S. states, stronger protections kept solar and wind projects out of intact landscapes.
The key idea
In the modeled scenarios, stronger land protections moved projects away from valuable habitats and made the system somewhat more expensive.
The study, in plain language
A net-zero future also requires decisions about where to place power plants and transmission lines. The team combined energy-system models with conservation maps to compare scenarios in 11 western U.S. states, with different electrification and land-protection options.
With few new restrictions, much of the planned solar and wind development could overlap with areas important for conservation. Stronger protections redirected it away from intact landscapes and wildlife corridors, and reduced the need for new transmission between states. In the model, these changes added a small cost compared with the more flexible scenario.
What they found
- Without new protections, a large share of solar and wind development in the high-electrification case could overlap with high-conservation-value areas.
- Stronger protections substantially reduced wind development in intact landscapes and wildlife corridors.
- Protection modestly increased projected costs and reduced additional transmission between states.
Something to think about
When you see a clean-energy plan, look at where it proposes to place power plants and lines, and what land-use choices are behind it.
How they studied it
The team combined energy models with conservation maps to compare pathways to net zero in 11 western U.S. states. They analyzed different electrification and land-protection options. These are modeled scenarios for 2050, not actual projects or observed prices. Distance from infrastructure is a proxy for visual exposure, not a measure of what each person would perceive.
What the study cannot show
- Results depend on assumptions about demand, costs, policies, technology, and available areas.
- The model left out resources on tribal lands to respect those communities’ sovereignty.
- It did not analyze every local effect on air, water, pollution, or soil.
