本論文は、2023年の再生可能エネルギー源の進展を国際データに基づいて総合的に分析。太陽光・風力が新規導入の96%を占め、世界の再生可能エネルギー発電比率は30%に達したが、化石燃料依存は81.47%と依然高く、温室効果ガス排出量は53.0GtCO2eqに上った。課題として、送電網・投資・政策・蓄電容量の不足を指摘し、NZE目標達成にはより強力な政策支援と国際協力が必要と結論付けている。
English
This paper provides an integrated analysis of renewable energy in 2023. Global renewable capacity additions reached 510 GW, with solar and wind comprising 96% of new installations. Despite record growth, fossil fuels still account for 81.47% of primary energy consumption. Key challenges include grid infrastructure, insufficient investment, policy barriers, and storage constraints.

📄 Abstract（原文）
Available online--This paper presents an integrated analysis of renewable energy sources in 2023 using international energy and climate datasets published during 2023 and 2024. The study examines developments in solar, wind, hydropower, bioenergy, geothermal, marine, and hydrogen technologies and evaluates their contribution to global energy supply in the context of Net Zero Emissions (NZE) targets. Renewable energy deployment continued to expand during 2023 and reached its highest annual growth on record. Global renewable capacity additions amounted to 510 GW, while solar and wind technologies represented 96% of new installations. As a result, renewable electricity generation increased to 30% of global electricity production. The strongest growth was observed in solar PV, whose installed capacity increased by 346 GW and reached 1419 GW by the end of 2023. Despite these developments, the global energy system remained heavily dependent on fossil fuels. Fossil fuels accounted for 81.47% of total primary energy consumption, whereas the contribution of renewable energy sources was 14.56%. At the same time, global greenhouse gas emissions reached 53.0 GtCO 2eq , atmospheric CO 2 concentration increased to 419.3 ppm, and global temperature rose to 1.45 ± 0.12°C above pre-industrial levels. The study shows that several challenges continue to slow the expansion of renewable energy. Limitations in grid infrastructure, insufficient investment, policy and regulatory barriers, and inadequate energy storage capacity remain major constraints, particularly in developing economies. Although renewable energy deployment reached record levels in 2023, progress remained below the pace required to achieve NZE targets. Stronger policy support, expanded grid infrastructure, increased climate finance, and greater international cooperation will be necessary to close this gap and support further progress toward NZE targets.
