Hydropower

From Open Energy Information

(Redirected from Hydro)

When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. Hydropower is the largest source of renewable electricity in the United States, allows the nation to avoid 200 million metric tons of carbon emissions each year, and is responsible for over 300,000 jobs with the potential to create thousands more.

Hydropower has been using water to make electricity for over a century. 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. Because the water cycle is an endless, constantly recharging system that is not reduced or used up in the hydropower process, hydropower is considered a renewable energy.

There are several types of hydroelectric facilities, all powered by the kinetic energy of flowing water as it moves downstream. Turbines and generators convert the energy into electricity, which is then fed into the electrical grid to be used in homes, businesses, and by industry. Hydropower facilities provide a number of benefits in addition to producing electricity, such as flood control, irrigation, water supply, and a range of recreational opportunities.
