This study models renewable energy expansion in the Cologne planning region using GIS and a siting algorithm. Under current planning, climate-neutral electricity production is unattainable; only a 50% reduction in energy demand makes targets achievable. Land requirements are substantial in all scenarios, profoundly reshaping landscapes.

日本のGX文脈において
ドイツの地域計画に焦点を当てた研究だが、日本でも再生可能エネルギー拡大における土地利用制約は重要な課題であり、GISを用いたシナリオ分析の手法は参考になる。ただし、日本の政策（FIT/FIP制度、地域計画）との直接的な関連は薄い。
In the global GX context
This paper provides a robust GIS-based methodology for assessing land-use constraints on renewable energy expansion, relevant to global energy transition planning. The finding that current planning frameworks may be insufficient highlights the need for integrated land-use and energy policy, applicable beyond Germany.
👥 読者別の含意
🔬研究者:The GIS-siting algorithm methodology offers a replicable approach for modeling renewable energy futures under land-use constraints.
🏢実務担当者:Energy planners can use these findings to understand the critical role of land availability and demand reduction in achieving climate targets.
🏛政策担当者:The study shows that current planning rules may need significant revision to allow enough land for renewables, and demand-side measures are essential.
📄 Abstract（原文）
Germany aims to become climate-neutral by 2045, which necessitates a far-reaching transformation of its energy system. Central to this shift is the ongoing expansion of renewable energy sources, particularly wind power and photovoltaics. This study seeks to model the growth of renewable energy systems in the Cologne planning region in western Germany in a way that is consistent with national and international climate targets. For this purpose, we employ a Geographic Information System (GIS)-based methodology combined with a siting algorithm. This allows us to apply land-use regulation scenarios to simulate various regulatory pathways and evaluate their effects on the resulting energy landscapes. The modeling period spans 2023-2045, and population data, CO₂ budgets, and electricity demand are derived for this timeframe. The findings indicate that climate-neutral electricity production in the region cannot be achieved under the current planning framework due to a lack of sufficient land for renewable energy installations. Even in scenarios with more flexible planning rules and higher-efficiency wind turbines, available land remains scarce. Only a substantial reduction in energy demand, modeled in this study at 50%, would make the targets attainable. Regardless, the energy transition would profoundly reshape the landscape, as land requirements are substantial in every scenario. Nonetheless, the region could still markedly increase the share of renewable electricity production through targeted measures. The study confirms that combining a GIS-based approach with a siting algorithm is a robust method for exploring alternative energy pathways.
