摘　　要：为了应对全球气候变化,我国将以水电为主的可再生能源列为能源替代战略的优先领域加以大力发展,以有效减少化石能源消费。本文简要介绍了能源回报率的定义和计算方法,在此基础上,对水电能源回报率进行了评估,并与其他发电形式的能源回报率进行了比较。结果显示,水电在所有发电模式中具有最高的能源回报率,在应对气候变化、节能减排等方面具有明显优势。China has listed the renewable energy based on hydropower as the priority area of energy substitution strategy for vigorous development in order to cope with the global climate change,thereby effectively reducing the consumption of fossil energy. The definition and calculation methods of energy return rate are briefly introduced in the paper. The hydropower energy return rate is evaluated on the basis,and it is compared with the energy return rate in other power generation mode.Results show that hydropower has the highest energy return rate among all power generation modes. It has prominent advantages in fighting with climate change,energy saving and discharge decreasing,etc.
