It is one of the most environmentally-friendly forms of energy production available to us today.

Why is hydropower important?

Hydropower is a flexible source of energy as hydropower plants can be scaled up and down easily to meet the changing energy demands. When the electricity demand is high, the flow of water can be increased and can also be decreased when the demand falls.

How does hydropower work?

The volume of the water flow and the elevation of the dam determines the amount of available energy in moving water. Generally, the greater is the water flow and the higher is the elevation of the dam, the more electricity can be produced. It is important to understand that hydropower relies on the water cycle.

What was the first source of energy?

Hydropower was one of the first sources of energy used for electricity generation. Hydropower accounts for around 18% of total electricity production. Photo by American Public Power Association on Unsplash.

How does hydroelectricity affect the water cycle?

It is important to understand that hydropower relies on the water cycle. Seasonal variation directly affects hydroelectricity production as water flow varies with seasons. For example, during the rainy season, the water flow is maximum while it is a minimum for summer. Also, some water sources dry in summer.

When is hydropower applicable

Hydraulic energy offers a continuous energy supply, although very limited and concrete. In addition, there needs to be a reservoir in a river or lake so that the force of the water is sufficient for the turbines to generate electricity.

The advantages and disadvantages of hydropower

As we will see, it has more advantages than disadvantages, and that is why it is currently the most widely used to supply electricity to homes and businesses.

Advantage

It is a renewable energy: when it is obtained from the fall of the water of a reservoir, which in turn feeds on the rain, as long as the water cycle is maintained and the reservoir does not dry out, the energy can continue to be produced hydraulic energy.

Disadvantages

It can be affected by droughts: although, as we have pointed out, a reserve of water is always maintained in the dams for when it does not rain, in areas where there are prolonged droughts this energy is not viable or involves expensive and difficult jobs, such as diversion from the bed of another river that feeds the reservoir.

How can hydropower be controlled?

The output of electricity can be easily controlled by controlling the flow of water. At times when electricity consumption is low, the hydropower plants can be adjusted easily to yield less energy and opposite when there’s high demand.

How long do hydropower plants last?

Durability. Hydropower plants are considered to be a one-time investment. They have an average life span of 50-100 years meaning one plant can support many future generations. Also, the maintenance cost is relatively low compared to the outcome.

What is hydropower used for?

In many places, hydropower is also used to operate many mechanical devices along with the production of electricity. A hydropower plant, however, is more focused on producing electricity on a large scale.

How does hydropower help the environment?

Hydropower plants produce energy without emitting any greenhouse gases or toxic byproducts that can pollute the environment. This makes hydropower plants a clean source of energy which helps mitigate world issues like climate change and global warming.

Why are dams built?

Big dams are built on large rivers which have a significant drop in elevation. The dams are responsible to store water which contains potential energy. When the water inlet is open, gravity causes the water to flow through the penstock (a large tunnel).

What are the recreational uses of dams?

Recreational Opportunities. The lake formed by the dam can be used for various recreational activities like fishing, swimming, and irrigational purposes. Dams have the capacity to store a tremendous amount of water which can be used for various activities when there’s a scarcity. 5.

How much does it cost to build a hydroelectric power plant?

Challenges like topography and building underwater make building a power plant really expensive. A 500 kW hydropower plant can cost you well over 1.5 million pounds which is an average estimate as generalizing is really difficult in this case.

How does hydropower affect the environment?

Hydropower plants can adversely affect surrounding environments. While hydropower is a renewable energy source, there are some important environmental impacts that come along with building hydroelectric plants to be aware of. Most importantly, storage hydropower or pumped storage hydropower systems interrupt the natural flow of a river system.

How does hydroelectricity work?

The majority of hydroelectric plants are storage or pumped storage facilities that store large amounts of water in reservoirs, and will almost always have stored water to pull from to generate power. Hydropower’s reliance on stored water in reservoirs means that it is generally a reliable source of power in the sense that hydropower plants can be a stable source of supporting energy for more intermittent energy sources like wind and solar. Wind power and solar energy rely on the natural availability of wind and sunlight; just like an energy storage system, at times of low wind or at night when the sun isn’t shining, hydropower provides electricity when solar and wind can’t, making them more economical and practical sources of electricity.

What are the pros and cons of hydropower?

Is hydropower a long term solution?

Fossil fuels like coal and oil must be burned to generate power and replenish very slowly, and as such are not a long-term energy solution.

How does the hydroelectric plant work?

Hydropower plants use water energy to generate electricity. This is stored as potential energy in the water stored in the reservoir. When the water is allowed to flow down, this turns into mechanical energy, which in turn is used to turn turbines. The rest of power generation is the same as in a coal-powered plant.

Hydroelectric energy: Pros and cons

Hydroelectric power continues to be the most popular renewable energy resource in the world. It accounts for more than 50% of installed power generation capacity.

Advantages of hydropower

Hydroelectricity harnesses the power of flowing water to generate electricity. It doesn’t even use up the water, which can be used for irrigation and domestic needs downstream. The natural water cycle ensures constant replenishment of water upstream. This is one of the main advantages of hydropower.

Disadvantages of hydroelectric energy

Building a dam across a river can submerge vast areas on both banks. This necessitates environmental clearance. This also means acquiring vast landscapes, which adds to the project cost.
