我国水力资源丰富,水能理论蕴藏量和可开发量均居世界首位,其中小水电资源总量在1.5亿千瓦,可开发容量7600万干瓦,年电能达2500亿千瓦时。以人均年用电量200～300千瓦时估算,全国有半数以上的县具备以开发小水电为主解决当地用电的条件。 中国的水电事业是从小水电起步的。 China’s water resources are abundant, and the hydropower theoretical reserves and exploitable amounts rank first in the world, among which the total amount of small hydropower resources is 150 million kilowatts, the capacity for development is 76 million kilowatts, and the annual energy is up to 250 billion kwh. Based on the average annual electricity consumption of 200 to 300 kWh, more than half of the counties in the country have the conditions for the development of small hydropower to solve local electricity demand. China’s hydropower business started from small hydropower.
