How Hydropower Works. Hydropower is using water to power machinery or make electricity. Water constantly moves through a vast global cycle, evaporating from lakes and oceans, forming clouds, precipitating as rain or snow, then flowing back down to the ocean.ecause the water cycle is an endless, constantly recharging system, hydropower is considered a renewable energy. When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower.
