20% of total electrical energy is generated from the hydroelectric power plant in the world. What is Hydroelectric Power? Altering the water streams, creating dams, and getting power can be easier said than done. In fact, the creation of hydroelectricity will not cause any contamination. Wildlife migrations may be dramatically altered, and there may be a loss of suitable habitat as well as a loss of important species. Basically, hydroelectric power is a clean and green alternative source of energy. Although renewable sources of energy such as solar and wind are fast catching up with the evaporating hydroelectric power, it still holds the largest share of the global electricity. thanks so much :) A Cheap Source of Energy. India also has a huge number of dams, nearly 2000 dams across the country. 2) Hydel power generation stations are to be located in hilly mountainous terrains where waterfalls as well as ideal sites for dams are located. The large reservoirs that form behind a dam with a hydroelectric power plant can submerse an extensive area upstream. 1.

This type of energy source is considered dependable as there are no issues so far as electric power generation is concerned. So now we will talk about all the disadvantages of power in detail step by step. Hydropower plants are generally located in hilly areas where water is easily available in huge quantity. 2. People living in nearby areas get uprooted. 1. For sort out this disadvantage, an auxiliary power plant is taken into consideration for a generation at that time. Disadvantages of Hydroelectricity . During the rainy reason a huge amount of water available at that time but during the summer seasons, not that much water is available for producing the required electricity. Your email address will not be published. This prevents fish from reaching their breeding ground, which in turn affects any animal that relies on those fish for food. Vulnerability to climate change 6 Advantages and Disadvantages of Hydroelectric Energy. Are there any disadvantages? Disadvantages of Hydroelectricity: Highly expensive. One disadvantage of the hydroelectric power plant is that it requires a high budget for the construction of the dam and the installation of the turbine. By simply constructing the site on its preferred location, it imposes threat to the natural habitat of many marine lives. Hydropower is totally depended upon the weather condition. By using high-quality material cost also increase in construction so these can be also one of the dangers of hydroelectric power. Once the establishment is in place, it will be easier to deflect the flow of water from one place to another. Let’s discuss some of the major advantages and disadvantages of hydropower: Advantages of Hydropower 1. This can cause the interruption of the natural flow of water from one direction to another. A reservoir is made to provide the required amount of water for generation during the shortage of water happens. Hydroelectric power is not perfect, however, and does have some significant disadvantages: Hydropower is non-polluting, but does have environmental impacts. See also –Â Advantages and Disadvantages of Nuclear Power Plant. Consequently, it can influence the movement of fish as they move or migrate. But there are some limitations and disadvantages of hydroelectric power also. However, it is not very hard to get going. But indirectly they disturb the environment. This process is referred to as hydroelectricity. In this article we will dive into the waters of hydroelectricity and find out the different advantages and disadvantages of Hydroelectric Energy, highlighting the pros and cons of the technology.. What are Advantages and Disadvantages Of Hydroelectric Energy In most cases this will not cause problems, but in tectonically active re… 5. 2. Requires Low Operating Cost. To begin with, here are a few points to ponder from the list of pros and cons of hydroelectricity as stated below. Humanity has been harnessing the power of flowing water for centuries. If you have any issue regarding this article kindly comment below I will surely help you soon. Undoubtedly, power plants are very expensive to create, regardless of the type of building. This disadvantage primarily impacts the traditional forms of hydroelectricity, but it could also alter how the tides come in as time passes. What Are The Pros of Hydropower; Green Energy Disadvantages of Hydroelectricity 1. hope now you know all disadvantages of hydroelectric power and negative effects of hydroelectric power. Since this method uses water from the earth to produce electricity, the resource is renewable. It is Renewable. More so, it can affect the livelihood of people living in these areas. 2. Despite expensive upfront building costs, hydroelectric power is one of the cheapest sources of energy. 1. Price of electricity is directly proportional to the generation of electricity from hydropower plant. Some of the issues include blocking of passage for migratory fish, changing of the river’s normal flow, and increasing possibility of earthquakes and displacement of communities within the area. Because hydroelectric power plants and dams utilize the flow of water, this also alters the natural flow of rivers. The activities involved in the construction of dam disturb the environment indirectly. The cost of energy and power are identified depending on the accessibility of water. The disadvantages of hydroelectric power include the followings. The high cost of d … Causes Environmental Damage. It also require minimal replacements due to the fewer parts that are present in it. Jan 14, 2017 Nov 16, 2016 by Editor in Chief. Hydroelectricity technologies are broadly classified into four categories – conventional (dams), pumped-storage, run-of-the-river and offshore marine (tidal). Floods in Lower Areas. The dams can also cause flooding of farmlands thus degenerating and water logging cultivable farmlands converting them into marshes. Consequently, this option has been criticized by local communities as it can disrupt the normal ecosystem. 2. Breakers and other switches cost high at an initial time. Hence, these facilities will be capable of providing hydroelectric power for a long period of time. This entry was posted on October 4, 2009 at 12:14 pm, and is filed under Disadvantages of Hydroelectricity.Follow any responses to this post through RSS.You can leave a response, or trackback from your own site. Ecological impacts 5. (Impact of hydropower on the environment) Hydropower is, like other sources of renewable energy, very expensive to implement, so it takes a long amount of time before a hydropower system will begin to return profits on the original cost of the investment. requires high-quality materials for constructing dams. May Cause Droughts. Every Hydropower plants have the limited reservoir which is not every time sufficient to provide necessary shortage water. Ripple factor of Half wave and full wave rectifier, Difference Between N type and P type Semiconductor | Quick Guide, Hydroelectric power generation creates environmental consequences. The principle will utilize the constant flow of water in order to move the turbines, which enable the use of the flowing water’s kinetic energy. When one of these factors will be altered, there can be a possible interruption in the ecosystem for sure. Pros of hydroelectricity There are some rather obvious advantages to using hydroelectricity over sources which require burning a non-renewable fuel:. list of Abuse of vulnerable populations 7. More so, the dams built in these locations have been designed for long-term use. So here, First we will see brief disadvantages of hydroelectric power and after that, we will going into detail about that particular point.
