双碳研究 | 【IRENA最新报告】2025年可再生能源统计：突飞猛进但仍任重道远

Core Insights - The International Renewable Energy Agency (IRENA) reported significant growth in renewable energy capacity in 2024, reaching a total of 4448 GW, with an addition of 585 GW, marking a record annual growth rate of 15.1% [4] - Despite the record growth, the progress is still lagging behind the target of tripling global renewable energy capacity to 11.2 TW by 2030, necessitating an annual growth rate of 16.6% [4][6] - There are notable regional disparities in renewable energy expansion, with Asia leading, particularly China, which contributed nearly 64% of the global new capacity [4] Renewable Energy Capacity Growth - In 2024, solar and wind energy accounted for 96.6% of the new renewable energy capacity, with solar energy growing by 32.2% to reach 1865 GW and wind energy increasing by 11.1% [5] - The growth in solar energy was particularly driven by China, which contributed 278 GW of the total increase of 451.9 GW in photovoltaic generation [7] - Hydropower capacity rebounded to 1283 GW, largely due to contributions from China, with several countries like Ethiopia and Indonesia also showing significant increases [7] Challenges and Future Goals - IRENA's Director-General emphasized the need for governments to set clear and quantifiable renewable energy targets in their next round of Nationally Determined Contributions (NDCs 3.0) to meet the 2030 goals [5][6] - The UN Secretary-General acknowledged the progress in renewable energy, highlighting its potential to create jobs, lower energy costs, and improve air quality, while stressing the urgency for a faster and fairer transition to clean energy [5] Sector-Specific Developments - Biomass energy saw a rebound in 2024, with an increase of 4.6 GW, primarily from China and France [9] - Geothermal energy capacity increased by 0.4 GW, with New Zealand leading the way [9] - Off-grid power capacity nearly tripled, growing by 1.7 GW to reach 14.3 GW, mainly driven by off-grid solar energy [9]
