What is Hydropower?
Hydro Energy is the creation of energy through the flow of water. For centuries, humans have used the power of water to make life easier. In its original form, hydro energy used large wooden wheels to create power. Today we use more sophisticated devices called turbines. These turbines spin as water flows through them, generating electricity. What makes hydropower a great source of renewable energy is that it can also store huge amounts of energy!
Think of hydroelectric power as harnessing the natural flow of water to generate electricity for your home. Imagine a river or stream with a dam. The water builds up behind the dam, creating potential energy. When the water is released, it flows through turbines, which spin and generate electricity.
For a homeowner, this means that some of the electricity you use might come from this process, making it a clean and renewable source of energy. Unlike fossil fuels, hydroelectric power doesn’t produce greenhouse gases or other pollutants, so it’s better for the environment. Plus, it’s a reliable source of energy as long as there’s a steady flow of water. So, when you hear about hydroelectric power, you can feel good knowing that it’s a sustainable way to help keep your lights on and your appliances running.
What is Hydropower Used For?
- Hydropower is used for electricity generation. Hydroelectricity stations are also used to provide flood control, irrigation support, as well as providing clean drinking water.
Right now, hydropower provides about 7% of the United States’ electricity and about 40% of its renewable energy. It’s also one of the most affordable and can provide a clean, sustainable, and reliable way to power our lives for centuries to come.

How Does Hydropower Work?
Water that flows from high to low passes over a turbine. This causes the turbine to spin and power a generator. In most cases of hydropower, building a dam creates a reservoir. Water flowing from the reservoir through the dam pushes against turbines causing them to spin. Those turbines are connected to a generator through a series of mechanics that turn the kinetic energy into electricity. Once electric energy is created, transmission lines deliver the power to homes a businesses at a set cost.
How Much Water Pressure does it take to turn a Hydropower Turbine?
- Each turbine has five blades with a stainless steel shaft inside the pipe. The minimum flow requirements are 20 cfs at 40 psi. Each turbine reduces head pressure by just 1 to 5 psi.
These “water batteries,” known as pumped storage hydropower, can store vast amounts of renewable energy for months. Unlike solar energy and wind power, water batteries can store surplus energy. In the United States, these facilities can store up to 553 gigawatt-hours of energy, which is sufficient to power the entire country’s video gaming for approximately a week.

What is the Cost of Hydropower?
The primary expense associated with hydroelectric power generation is the initial construction and subsequent maintenance of the facility. Well-built facilities tend to have relatively modest maintenance costs, and these plants can operate for several decades or even longer. States heavily reliant on hydropower, such as Idaho, Washington, and Oregon, enjoy some of the lowest electricity bills in the United States.
Is Hydropower Expensive to Run?
- Hydropower stands as an affordable electricity source that is cheaper than most alternatives.
New hydropower technologies keep getting better, too. It’s now easier to build new facilities without too much disruption to the local environment. And newer technology can cut construction costs, which could make water energy even more affordable, potentially reducing energy bills across the country.

What are the Benefits of Hydropower?
Hydroelectric power is an excellent green energy option due to the widespread abundance of water. However, it is important to acknowledge certain environmental drawbacks associated with hydropower. While the power generation process itself is free from carbon dioxide emissions, the construction of dams along rivers can have adverse effects on native fish species.
Pros:
- Renewable: Hydropower uses the natural water cycle to generate electricity. As long as there are rivers and rainfall, we can produce hydroelectric power. This means it won’t run out, unlike fossil fuels.
- Low Emissions: Using water to generate electricity doesn’t produce harmful greenhouse gases or air pollutants. This makes hydropower a clean and environmentally friendly option, helping reduce your carbon footprint.
- Reliable: Hydroelectric power plants can produce electricity consistently as long as there’s a steady water supply. This means less reliance on fossil fuels and a more stable energy source for your home.
- Safe: Hydropower plants are generally safe to operate and don’t pose the same risks as nuclear power plants or coal mines.
Cons:
- Environmental Consequences: Building dams and reservoirs can disrupt local ecosystems, affecting fish populations and wildlife habitats. This can sometimes lead to negative impacts on the surrounding environment.
- Expensive to Build: Constructing a hydroelectric power plant is a big investment. The initial costs are high, which can make hydropower more expensive to develop compared to other renewable energy sources.
- Drought Potential: Hydropower depends on water availability. During droughts or dry seasons, the water levels can drop, reducing the amount of electricity generated. This can make hydropower less reliable in areas prone to drought.
- Limited Resources: Not every location is suitable for building a hydropower plant. It requires specific geographic conditions, such as a flowing river and the ability to construct a dam. This limits where hydropower can be developed.

Hydroelectric Power FAQ
Q: What is the definition of hydroelectricity easy?
A: Hydropower, also known as hydroelectric power, is a renewable energy source that produces electricity through the manipulation of a river or other water bodies’ natural flow by employing a dam or diversion structure.
Q: Where is hydroelectricity used?
A: The majority of hydroelectricity generation capacity in the United States is concentrated in the western region. Virtually all states in the country have conventional hydroelectric facilities. Large dams constructed by the federal government contribute significantly to the production of hydroelectricity, and many of the largest hydropower dams are located in the western United States.
Q: What Are Hydroelectric Power Plants?
A: Hydropower plants play a crucial role in providing essential backup power during significant electricity outages or disruptions due to their ability to generate power for the grid instantaneously. However, the benefits of hydropower extend beyond electricity generation. These plants also contribute to flood control, support irrigation systems, and provide clean drinking water, offering a range of additional advantages to communities and ecosystems.
