本論文はPRISMA 2020に沿った系統的レビューにより、再生可能エネルギーの気候変動緩和における役割を世界およびインドの文脈で検討した。2015〜2025年の世界発電量とインドの導入容量（81.31GW→220.10GW）の拡大を示し、太陽光がCAGR38.77%で最大の伸びを記録した。GHG削減・エネルギー安全保障・雇用創出などの便益と、間欠性・初期投資・系統インフラ・政策不確実性といった障壁を整理し、安定政策・蓄電池・系統近代化・国際協力を提言する。
English
This PRISMA-guided systematic review examines renewable energy's role in climate mitigation globally and in India. It documents rapid growth in global generation (2015–2025) and India's capacity expansion from 81.31 GW to 220.10 GW, with solar leading at 38.77% CAGR. It maps benefits (GHG cuts, energy security, jobs) against barriers (intermittency, upfront cost, grid gaps, policy uncertainty) and calls for stable policy, storage, grid modernization, and international cooperation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では第7次エネルギー基本計画やGX推進法のもとで再エネ比率引き上げが焦点となっており、太陽光の急拡大と系統・蓄電池の制約というインドの経験は、日本の電源構成・系統制約・政策安定性を考える上で参照価値がある。ただし開示・Scope・TCFD/SSBJとの直接接続は薄い。
In the global GX context
For global disclosure scholarship, this paper sits upstream of TCFD/ISSB reporting: it supplies the transition-pathway and capacity evidence that corporate transition plans and country-level NDCs draw on. Its India-focused empirical detail adds a Global South perspective often underrepresented in transition-finance and disclosure literature dominated by EU/US cases.
👥 読者別の含意
🔬研究者:再エネ導入と政策障壁に関する世界・インドの定量トレンドを整理する基礎資料として有用。
🏢実務担当者:再エネ調達や脱炭素戦略の立案時に、系統・蓄電池・政策リスクの論点を把握する参考になる。

📄 Abstract（原文）
The transition of fossil fuel-based energy systems to renewable energy has become a key strategy to reduce greenhouse gas emissions and enhance low-carbon development. This study examines renewable energy and its role in the climate change mitigation process by examining environmental, economic and social benefits, pathways and transitions, including policy implications in global and Indian contexts. The study followed qualitative, descriptive and systematic review methods, guided by PRISMA 2020, with secondary data from academic and institutional sources as relevant. Global electricity generation, according to the findings, shows significant growth over the period of 2015 to 2025. Among the renewable sources, hydropower takes the largest share with 4,434.97 TWh in 2025, indicating expansion from 3,882.13TWh from 2015. Solar and wind also experienced rapid expansion, producing 2,778.64 TWh and 2, 713.14 TWh in 2015 from 256.01 TWh and 829.08 TWh in 2015 respectively. The results indicate that the total capacity of renewable energy has increased from 81.31 GW in 2014–15 to 220.10 GW in 2024–25 in India. Solar energy was the largest component with a total of 66.78 GW and the highest CAGR of 38.77% compared to 7.92% for wind, 2.60% for bioenergy and 2.31% for small hydropower. The study further demonstrates the potential of renewable energy in GHG reduction, energy security, job creation, economic development, public health and sustainable environment management. Intermittency, high initial investment costs, inadequate grid infrastructure, policy uncertainty and technological limitations, however, remain as significant barriers. Therefore, the present study gives importance to stable policies, financial incentives, grid modernisation, energy storage, technological innovation, international cooperation and institutional capacity-building as essential measures for accelerating a resilient, low-carbon and sustainable energy transition.
