高分解能エネルギーシステムモデルは経済格差を考慮せず、技術的に可能だが経済的に非現実的な結果を生む可能性がある。本研究は、欧州のネットゼロエネルギーシステム設計にGDPと家計所得の格差を組み込み、経済格差に対応した設計が可能であり、総コスト増は1.1%に留まることを示す。また、低所得国では暖房転換に家計レベルの資金調達が必要であると指摘する。

High-resolution energy system models often ignore economic disparity, leading to technically feasible but economically unrealistic outcomes. This study integrates GDP and household income disparity into a net-zero European energy system model, finding that disparity-compatible designs are possible with only 1.1% total system cost increase. It also highlights that less affluent European countries may need household-level financing for heating transitions.

📄 Abstract（原文）
Abstract High-resolution energy system models, as powerful tools to represent energy systems in detail and assist energy transition planning, rarely account for economic disparity, unlike broader-scale tools such as integrated assessment models. In this study, by analysing net-zero European energy system designs through the lens of national GDP and household average income, we find that disparity-unaware high-resolution energy system models can produce results that are technically feasible but largely incompatible with economic realities. The investment in household heating technology may be disproportional to the income level of lower-income countries. Explicitly acknowledging economic disparity in such models reduces the danger of them proposing solutions which burden economically disadvantaged actors. Therefore, here, we explicitly include national GDP and household income disparity in a model for net-zero European energy system designs. We find that disparity-compatible systems are possible with a 1.1% total system cost increase compared to the least-cost ones. Unlike in disparity-unaware system designs, where energy infrastructure investments often reach over 20% of national GDP for some countries, we develop disparity-compatible designs which limit investments to below 5% in each country. Our results show that less affluent European countries may need substantial household-level financing to support their heating transition and to diversify their net-zero energy technology choices.
