本論文は、再生可能エネルギーの普及がエネルギー関連不確実性（EUI）の緩衝材として機能し、国内経済に私的便益をもたらすことを実証。28カ国のパネルデータを用い、高再生可能エネルギー比率の状態ではEUIショックの影響が有意に緩和されることを示した。これにより、再生可能エネルギー促進が地球公共財への貢献だけでなく、国内のリスク管理としての経済的根拠を持つことを明らかにした。
English
This paper empirically shows that renewable energy adoption acts as a buffer against energy-related uncertainty, providing private benefits to domestic economies. Using panel data from 28 countries, it finds that in high renewable share regimes, the impact of energy uncertainty shocks is significantly moderated. This offers a novel economic rationale for national policy interventions, shifting the incentive from global altruism to national risk management.

📄 Abstract（原文）
Renewable energy has been promoted globally to mitigate climate change, yet its adoption is often hindered by the free-rider problem inherent in the voluntary provision of global public goods. This paper investigates whether the promotion of renewable energy provides a national-level benefit by functioning as a buffer against energy-related uncertainty. Utilizing a state-dependent model and local projections for a panel of 28 countries from 2000 to 2022, we analyze the dynamic response of the Energy-related Uncertainty Index (EUI) to its own unpredictable shocks. Our empirical results demonstrate that a high share of renewable energy in total final energy consumption effectively offsets fluctuations in energy-related uncertainty. Specifically, in a high renewable energy share regime, the impact of an EUI shock is significantly moderated 1–2 months after the initial disturbance compared to a low-share regime. These findings provide a novel economic rationale for national policy interventions by showing that the stabilizing effects of renewable energy accrue as a private benefit to the domestic economy rather than a purely global, non-excludable gain. By acting as an internal mitigating factor against energy-market shocks, renewable energy use shifts the incentive structure from global altruism to national risk management, offering a practical pathway for countries to accelerate the attainment of Target 7.2 of the Sustainable Development Goals (SDGs).
