大力发展水电,是解决中国21世纪经济社会可持续发展面临的水资源、能源、粮食、环境四个重大问题的有效途径。水电作为清洁可再生能源,对于保证能源安全可靠供应、优化能源结构、促进节能减排具有重大意义;同时水电兼具调峰节能、储能节能等特性,是能源可持续发展的重要基础。 Vigorously developing hydropower is an effective way to solve the four major issues concerning water resources, energy, food and environment that China faces in sustainable economic and social development in the 21st century. Hydropower as a clean renewable energy source is of great significance to ensure the safe and reliable supply of energy, optimize the energy structure and promote energy conservation and emission reduction. At the same time hydropower has the characteristics of peak regulation, energy conservation, energy storage and energy saving, and is an important foundation for sustainable energy development.
