The Uses of Hydropower Energy

Hydropower is energy collected from flowing water that's converted into electricity or used to power machinery. Hydropower has been around for centuries, used to turn millwheels or drive early industrial machinery, but in modern use it typically refers to electrical generation. Today hydropower generates more electricity in the United States than any other renewable energy source, and the Department of Energy's Wind and Water Power Program promotes and accelerates its use throughout the country. For businesses, hydro offers recruiting benefits alongside a cost-effective and plentiful source of green energy. Generating Clean Electricity A primary use of hydropower energy is to produce electricity. The main ingredients of hydroelectric power plants are dams, rivers and turbines. Plants use dams to create reservoirs where the water is stored. This water is then released through turbines and spun to activate generators and create electricity. The first hydropower electrica

Types of Hydropower Plants

                                                   There are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not. The images below show both types of hydropower plants. MPOUNDMENT The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. The water may be released either to meet changing electricity needs or to maintain a constant reservoir level.                                                www.boland-hydroturbine.com DIVERSION A diversion, sometimes called run-of-river, facility channels a portion of a river through a canal or penstock. It may not require the use of a dam. PUMPED STORAGE Another type of hydropower called pumped

10 Things You May Not Know about Hydropower

https://www.boland-hydroturbine.com/ 10.Hydropower is one of the oldest power sources on the planet, generating power when flowing water spins a wheel or turbine. It was used by farmers as far back as ancient Greece for mechanical tasks like grinding grain. Hydropower is also a renewable energy source and produces no air pollution or toxic byproducts. Learn more about the history of hydropower. 9. When most people think of hydropower, they imagine the Hoover Dam – a huge facility storing the power of an entire river behind its walls – but hydropower facilities can be tiny too, taking advantage of water flows in municipal water facilities or irrigation ditches. They can even be “dam-less,” with diversions of run-of -river facilities channeling part of a stream through a powerhouse before the water rejoins the main river. 8. Niagara Falls was the site of the country’s first hydroelectric generating facility -- built in 1881 when Charles Brush connected a generator to turbines powe
