65カ国のパネルデータを用い、再生可能エネルギー比率がエネルギー充足性に与える影響を閾値モデルで分析した研究。単一閾値の存在が確認され、閾値は3.9%で、これを超えると正の効果が現れる。断片的な再エネ投資では充足性は改善せず、一定規模以上の比率が必要であることを示唆する。
English
Using panel data from 65 countries and a threshold model, this study examines how renewable energy share affects energy sufficiency. It finds a single threshold at 3.9%, above which the effect turns positive, implying fragmented renewable investment cannot improve sufficiency. Renewable share must exceed a critical level to enhance energy sustainability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策にとって、再エネ導入の「規模の閾値」を示す知見は、第7次エネルギー基本計画や再エネ比率目標の設計、断片的な地域投資の統合を議論する際の実証的裏付けとなりうる。
In the global GX context
Adds cross-country empirical evidence on non-linear renewable-sufficiency links, relevant to global energy transition policy design and to debates on whether incremental renewable procurement delivers system-level sufficiency gains.
👥 読者別の含意
🔬研究者:Provides a threshold-model template and cross-country evidence on non-linear renewable–sufficiency relationships.
🏢実務担当者:Suggests that small, fragmented renewable procurement may not yield sufficiency benefits, favoring scale.
🏛政策担当者:Indicates renewable targets should exceed a critical share threshold to deliver energy sufficiency gains.
📄 Abstract（原文）
The green energy development can serve a dual purpose of achieving economic as well as environmental sustainability. However, increasing its share can have non-linear impact on energy sufficiency. This study uses the data over globe by using threshold methodology, explores renewable share impact on energy sufficiency. The findings present an evidence for presence of non-linear relations. The result provide evidence for single threshold model. The magnitude of the threshold level turns to be 3.9% with positive effect above this level. The result imply that fragmented investment in renewable energy is unable to improve energy sufficiency. Therefore renewable share must be beyond a threshold. Further, the positive effect above threshold indicates enhancing energy sustainability to renewable share in energy mix.
