Nothing is perfect on Earth, and that includes the production of electricity using flowing water. Hydroelectric-production facilities are indeed not perfect (a dam costs a lot to build and also can have negative effects on the environment and local ecology), but there are a number of advantages of hydroelectric-power production as opposed to fossil-fuel power production.

Advantages of hydropower
- Hydropower is a renewable source of energy.
- The energy generated through hydropower relies on the water cycle, which is driven by the sun, making it renewable.
- Hydropower is fueled by water, making it a clean source of energy.
- Hydroelectric power is a domestic source of energy, allowing each state to produce its own energy without being reliant on international fuel sources.
- Impoundment hydropower creates reservoirs that offer recreational opportunities such as fishing, swimming, and boating. Most hydropower installations are required to provide some public access to the reservoir to allow the public to take advantage of these opportunities.
- Hydroelectric power is flexible. Some hydropower facilities can quickly go from zero power to maximum output. Because hydropower plants can generate power to the grid immediately, they provide essential backup power during major electricity outages or disruptions.
- Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water.
- Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy. Construction costs can even be mitigated by using preexisting structures such as bridges, tunnels, and dams.
- Hydropower complements other renewable energy sources. Technologies like pumped storage hydropower (PSH) store energy to use in tandem with renewables such as wind and solar power when demand is high.
- Hydropower is an established industry in the United States, employing 66,500 people. And there are a growing number of jobs available in hydropower, including manufacturing, utilities, professional and business services, construction, trade and transportation, energy systems, water management, environmental science, welding, machinery, and other services.
- The U.S. hydropower workforce could grow to 120,000 jobs by 2030 and 158,000 by 2050. For those interested in becoming part of this workforce, hydropower education programs can be found nationwide.
- Hydropower creates jobs in rural locations and boosts local economies.

Water Use Information by Topic
Water is everywhere, which is fortunate for all of humanity, as water is essential for life. Even though water is not always available in the needed quantity and quality for all people everywhere, people have learned to get and use water for all of their water needs, from drinking, cleaning, irrigating crops, producing electricity, and for just having fun.
Hydroelectric Power: How it Works
So just how do we get electricity from water? Actually, hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller-like piece called a turbine.
Hydroelectric Power Water Use
Hydropower, or hydroenergy, is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants. The falling water rotates blades of a turbine, which then spins a generator that converts the mechanical energy of the spinning turbine into electrical energy. Hydroelectric power is a significant component of electricity production...
