单项选择题：中国能源结构主要以煤炭为主，而目前中国煤炭发电平均效率只有35%，如果使用更多的先进

题目：

中国能源结构主要以煤炭为主，而目前中国煤炭发电平均效率只有35%，如果使用更多的先进技术，这一效率有望提高到50%甚至更高。在化石能源占主要比重的今天，提高传统能源效率和发展可再生能源同等重要。而要保证能源的可持续供应，除了以上两点，还有就是要加快智能电网的建设，也就是在整个能源的生产、传输和使用方面实现智能化的管理。对这段文字理解不正确的是：

A．中国应该抓紧技术研发与引进，努力提高能源利用效率

B．中国应该优化能源结构，大力降低化石能源比重。提高可再生能源比重

C．智能电网的建设也是实现能源可持续供应的一条有效途径

D．我国的能源利用效率偏低，有很大的提升空间
