中国领跑全球清洁能源投资

Core Insights - China's energy investment expenditure has reached twice that of the EU and is close to the combined total of the EU and the US, solidifying its position as the global leader in energy investment [2][4][7] Global Clean Energy Investment Trends - Global clean energy investment is expected to grow to $3.3 trillion by 2025, with clean energy investments projected to reach $2.2 trillion, approximately double that of fossil fuel investments [4] - China is projected to account for $630 billion, or 29% of global clean energy investments, exceeding the total expected investment from all developed economies [6][4] Investment Structure and Key Sectors - Over the past decade, China's share of global clean energy investment has increased from 25% to nearly 33%, maintaining a leading position in solar manufacturing, onshore and offshore wind power, and electric vehicle supply chains [6][7] - Solar photovoltaic investment is expected to attract $450 billion by 2025, making it the largest single energy investment sector globally [7] Regional Investment Disparities - There is a growing disparity in investment activity across regions, influenced by policy environments, electricity price changes, and adjusted return expectations [9][11] - The US has seen a significant decline in renewable energy investment, with a 36% drop in the first half of 2025 compared to the previous year [11] Emerging Markets and Growth Areas - Emerging markets like Saudi Arabia, India, Turkey, and Indonesia are experiencing stable growth in solar and wind investments, with Indonesia's investment scale increasing nearly fivefold [12] - Southeast Asia's renewable energy investment has grown by 7% quarter-on-quarter, indicating ongoing expansion in distributed solar and other sectors [12] Technological Investment Shifts - Solar photovoltaic continues to dominate global clean energy investment, with $252 billion invested in the first half of 2025, significantly outpacing wind investment [14] - Distributed solar is becoming a key growth area due to its shorter construction cycles and clearer revenue mechanisms, with investment in this sector doubling in China this year [14][15] Grid Investment Challenges - Despite global grid investments reaching $400 billion annually, this is insufficient to meet the rapid expansion of renewable energy, with complex approval processes and supply chain constraints hindering further investment [15]
