EUROSTATデータを用い、EU-27の電力・運輸・冷暖房における再エネ比率を2004–2024年にわたり比較。全部門で進展したが、電力が先行し運輸が制約となった。比率の相対的ばらつきは縮小した一方、絶対的格差は拡大し、部門間・国間の非対称性が鮮明になった。
English
Using EUROSTAT SHARES data for EU-27 (2004–2024), this study compares renewable shares across electricity, transport, and heating/cooling. All sectors advanced, but electricity led while transport lagged. Relative dispersion fell yet absolute gaps widened, revealing sectoral and cross-country asymmetry in the transition.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EUの部門別再エネ進捗の非対称性は、日本のエネルギー基本計画や再エネ導入目標の部門別設計を検討する上で参照価値が高い。特に運輸部門の遅れは日本でも共通課題であり、政策立案の示唆を与える。
In the global GX context
This paper quantifies sectoral asymmetry in EU renewable deployment, offering a benchmark for global stocktake and national energy transition planning. It highlights that aggregate renewable success can mask transport-sector bottlenecks, relevant to ISSB/TCFD transition planning.
👥 読者別の含意
🔬研究者:EU再エネ移行の部門別・国別不均一性を定量化した実証研究として、移行経路分析の基礎資料となる。
🏢実務担当者:自社の再エネ調達戦略において、部門別の進捗差を踏まえたリスク評価に活用できる。
🏛政策担当者:部門別目標設定や政策介入の優先順位を検討する際のエビデンスとして有用。
📄 Abstract(原文)
Has the renewable transition in the EU-27 advanced evenly across all final energy uses, or has it relied on one channel of decarbonisation more than others? Drawing on harmonised EUROSTAT SHARES statistics for a balanced panel of 27 Member States over 2004-2024 (567 country-year observations per sector), we compare renewable shares in electricity, transport, and heating and cooling at the level of the weighted EU-27 aggregate, the unweighted cross-country distribution, and the sectoral mix within each country, using five dispersion measures to distinguish relative from absolute heterogeneity. All three sectors progressed, but in different ways: electricity led the expansion (15.871% in 2004 to 47.500% in 2024 at the EU-27 aggregate), heating and cooling grew steadily (11.735% to 26.697%), and transport remained the binding constraint (1.432% to 11.204%). Proportional dispersion fell in every sector, yet absolute gaps widened: the frontier-laggard gap grew from 61.627 to 79.410 percentage points (pp) in electricity, from 6.288 to 25.463 pp in transport, and from 44.894 to 59.915 pp in heating and cooling, while the mean within-country gap between the strongest and weakest sector nearly doubled, from 19.753 to 38.898 pp. The EU transition has shared a direction without sharing a sectoral pattern, which matters for how aggregate success in renewable deployment is interpreted.
