IRENA統計を用い、2001〜2025年の世界の再エネ設備容量の成長と構造変化を太陽光・風力・水力等別に分析。太陽光と風力が最速で成長する一方、水力は基数が大きいが伸びは鈍い。投資・雇用・技術革新・エネルギー安全保障の経済的意義と、間欠性・蓄電・系統・鉱物供給・資金・政策不確実性という課題を整理する。
English
Using IRENA capacity statistics, this study analyzes the growth and structural shift of global renewable energy from 2001–2025 across solar, wind, hydro, biomass, geothermal and marine sources. Solar and wind grow fastest, while hydropower retains a large but slower-growing base. It highlights economic benefits (investment, jobs, energy security) alongside challenges of intermittency, storage, grids, critical minerals, financing and policy uncertainty.

📝 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推進戦略のもとで再エネ比率引き上げが焦点。本稿は太陽光・風力の成長速度と系統・蓄電・資金制約を示し、国内の電源構成議論や企業の再エネ調達戦略の背景整理に資する。
In the global GX context
For global readers, this offers a long-horizon, source-by-source view of renewable capacity growth that contextualizes transition-finance and disclosure debates (TCFD/ISSB) by quantifying where decarbonization is actually happening and where bottlenecks (grids, storage, minerals) persist.

📄 Abstract（原文）
The global energy system is undergoing a significant transformation from fossil-fuel-based energy towards renewable and low-carbon energy sources. This study analyses the growth and structural transformation of global renewable energy capacity during 2001–2025, focusing on solar, wind, hydropower, biomass, geothermal and ocean/marine energy. Secondary data compiled from International Renewable Energy Agency (IRENA) renewable-capacity statistics are examined using five-year periods. Trend analysis, growth-rate analysis, compound annual growth rate (CAGR) and percentage-share analysis are applied to assess changes in renewable energy capacity and identify the major drivers of the global energy transition. The findings indicate a substantial expansion in total renewable capacity, with solar and wind emerging as the fastest-growing renewable sources, while hydropower continues to maintain a significant installed-capacity base but with comparatively slower growth. The study also highlights the economic importance of renewable energy through investment, employment, technological innovation, energy security and reduced dependence on fossil fuels. However, intermittency, energy-storage requirements, grid infrastructure, critical-mineral supply, financing constraints and policy uncertainty remain major challenges. The study concludes that the global energy transition represents both an environmental and economic transformation and requires coordinated investment, technological development and supportive policy measures to achieve a secure, affordable and sustainable energy system.
