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.
Why is hydropower so reliable?
Since hydropower is so reliable, hydro plants can actually adjust the flow of water. This allows the plant to produce more energy when it is required or reduce the energy output when it is not needed. This is something that no other renewable energy source can do.
What are the advantages of hydroelectric power?
1. Renewable. Hydropower is completely renewable, which means it will never run out unless the water stops flowing. As a result, hydro plants are built to last. In some cases, equipment that was built to last 25 years is still operational after double the amount of time has passed.
Why are hydro dams important?
Faster Developed Land. Since hydro dams can only be built in specific locations, they can help develop the land for nearby towns and cities. This is because it takes a lot of equipment to build a dam. To transport it, highways and roads must be built, which helps open new paths for rural towns.
What is the biggest dam failure in history?
While these dams are built very strong, there are still risks. The biggest dam failure in history is the Banqiao Dam failure. Due to excess rainfall from a typhoon, the dam collapsed. This resulted in the deaths of 171,000 people.
How do hydro plants work?
To create a hydro plant, a running water source must be dammed. This prevents fish from reaching their breeding ground, which in turn affects any animal that relies on those fish for food. As the water stops flowing, riverside habitats begin to disappear. This can even remove animals from accessing water.
What happens to plants when they die?
Plants that are at the bottom of a reservoir begin to decompose. And when plants die, they release large quantities of carbon and methane.
Why are lakes important?
Lakes can be used for recreational purposes and can even help draw in tourists. Look no further than Lake Mead. It was created as a result of the Hoover dam and brought in over 7.5 million visitors in 2018. This can give nearby towns a huge boost economically.
Why are dams built across rivers?
Huge dams are built across rivers in countries rich with potential hydroelectric power source. This can cause the interruption of the natural flow of water from one direction to another.
Why is hydroelectricity good?
Requires Low Operating Cost. The good thing about hydroelectricity when it comes to cost is that it requires low maintenance and operating cost. It also require minimal replacements due to the fewer parts that are present in it. More so, the dams built in these locations have been designed for long-term use.
What is hydroelectric power?
