Core Viewpoint - The "Two Mountains" concept, proposed 20 years ago, has significantly influenced China's path towards high-level ecological protection and high-quality development, reshaping the country's development trajectory and ecological landscape while providing a global framework for harmonious coexistence between humans and nature [1][11]. Group 1: Historical Context and Development - The "Two Mountains" concept has evolved from local practices in Yucun, Zhejiang, to a national and global model, emphasizing ecological protection as a foundation for sustainable development [3][11]. - The concept has led to a fundamental shift in energy development from reliance on fossil fuels to a focus on clean energy, with the share of clean energy installations in China rising from 23% in 2005 to over 60% by 2025 [6][11]. Group 2: Practical Applications and Innovations - The implementation of the "Two Mountains" concept has resulted in various successful local initiatives, such as transforming Yucun from a "stone economy" to a tourism-based economy reliant on clean energy [3][4]. - Technological advancements in renewable energy have been significant, with solar cell efficiency reaching 34.8% and offshore wind turbine capacity reaching 26 megawatts, showcasing China's leadership in the global renewable energy market [7][11]. Group 3: Economic and Environmental Synergy - The "Two Mountains" concept illustrates that high-level ecological protection is not a constraint on economic development but rather a crucial support for high-quality growth, as evidenced by Zhejiang's economic performance with only 1.1% of the country's land and 3.4% of its energy consumption while generating 6.7% of the national GDP [6][10]. - The concept promotes a virtuous cycle where ecological protection enhances economic value, leading to improved livelihoods and contributing to common prosperity [10][11]. Group 4: Global Impact and Future Outlook - China's commitment to the "Two Mountains" concept has positioned it as a key player in global green development, contributing to one-fourth of the world's new green areas and actively participating in international renewable energy projects [11][12]. - Looking ahead, the "Two Mountains" concept is expected to drive global energy transformation, facilitating a shift from industrial civilization to ecological civilization, benefiting people worldwide [12].
