ポルトガルの再エネ760件を分類し、多変量クラスター分析で18の「エネルギー・土地システム」類型を特定した研究。風力は北部で放牧・養蜂等との共立地・共治が進み、太陽光は南部で生産量と外部性緩和が特徴。大規模案件は社会生態学的に周縁化された地域に立地し対策も多い一方、小規模案件は生産性の高い土地を占める傾向がある。
English
A nationwide Portuguese study classifying 760 renewable projects into 18 'energy-land system' types via cluster analysis. Wind in the North favors co-location and co-governance; solar in the South is defined by output and externality mitigation. Large projects cluster in marginalized regions with more socio-ecological measures, while smaller ones occupy more productive land—revealing deployment trade-offs.

📄 Abstract（原文）
Abstract. The expansion of solar and wind power creates complex "energy-land systems" defined by interactions between governance, land use, and energy production. While critical for the energy transition, utility-scale projects often face social contestation rooted in the socio-ecological marginalization of rural areas. Addressing these challenges requires a granular, nationwide understanding of renewable energy systems and their local contexts. Focusing on Portugal, we categorized 760 renewable energy projects and used multivariate cluster analysis to identify 18 energy-land system types. Deployment contexts were analysed using indicators of socio-ecological marginalization, including land degradation, energy poverty, income levels, demographic dynamics, and land prices. Our findings reveal that geography and scale are primary drivers of energy-land system diversity. Wind systems in the North favour co-location (e.g., pasture, beekeeping) and co-governance (e.g., protected areas, commons), while solar systems in the South are distinguished by production levels and externality mitigation. Furthermore, we found that large-scale projects are frequently located in highly marginalized regions and incorporate more socio-ecological measures. Conversely, smaller utility-scale projects tend to occupy more productive, less marginalized land. These patterns illustrate trade-offs between deployment strategies—such as few large projects versus several small ones—with direct implications for energy policies. To our knowledge, this study presents the first nationwide analysis of energy-land systems, providing a replicable approach for system characterization. By adopting a land-system perspective, this research supports planning decisions aimed at creating multifunctional, equitable systems that better align rural needs with the requirements of the energy transition across various scales.
