Their fast response times enable Advantages of Hydroelectric Energy 1. A local town proposes switching to hydropower for its electricity needs. Two primary disadvantages of hydroelectric power include the high investment cost and its reliance on precipitation. Aug 3, 2018 Jul 8, 2018 by Editor in Chief. Hydropower facilities can have a negative impact on the environment, despite not causing pollution, including the loss of fish habitats, displacement of the local population and the inundation of surrounding land. It … 10 Advantages and Disadvantages of Hydroelectricity. Which of the following is the largest disadvantage of hydropower? Explanation : Hydropower is a renewable source of energy. According to the 2019 Hydropower Status Report, hydroelectricity gave us a whopping 21.8 GW of energy and grew by 9% over the year. Due to the water cycle, the availability of water to generate electricity is almost endless. Hydropower is a natural form of energy that harnesses the sea’s tides or the motion of rivers. The main advantages of this type of energy are: 1. Q1-Which of the following is a disadvantage of renewable energy? a) High pollution b) Available only in few places c) High running cost d) Unreliable supply Explanation: Renewable energy often relies on the weather for its sources of power. It is based on the power of the water, and by building a dam on a river, the water is accumulated, and its power used for production of electrical energy. Advantages of Hydropower: Hydro power is a very efficient source of renewable energy. Hydroelectric Energy Is Renewable. The advantages of Hydropower are summarized below: 1. Hydropower is completely renewable, which means it will never run out unless the water stops flowing. Dams negatively impact the environment. It is a mature technology and its strengths and weaknesses are equally well understood. It could cause flooding and displace wildlife. This can be harnessed through the construction of dams across rivers. moving air. Advantages of Hydropower. Environmentally friendly. Advantages and disadvantages of hydropower schemes can be listed in terms of economic, social and environmental aspects. It is a new type of power that other towns have not tried. For this reason, hydropower is a renewable energy source with high energy efficiency. Renewable energy sources _____. ... Hydropower uses the kinetic energy of water to generate electricity. Hydro generators need rain to fill dams and thereby provide electricity. As a result, hydro plants are built to last. Hydropower is the most widely used renewable energy technology. In hydropower station, the graphical representation of discharge as function of time is known as The hydroelectric power plant having flow rate 1000 cubic meter/s and 800 m high head having plant efficiency of 96% will generate how many kilowatts Dams release harmful chemicals and toxins. Explanation: The hydropower is a one of the most commonly used in the world. Hydropower systems are very efficient because of the density of water, the force of gravity and the technological advantages of today. Hydropower is a nonrenewable resource. One of the effective methods of producing power is through the use of streaming or falling water. Answer : The disadvantage of using hydropower is Land can be flooded, displacing people and wildlife. In hydropower, electricity is generated using the mechanical energy of moving water. Hydropower depends on time of day. Wind machines use the power of _____. It relies on wind activity, so power could change with the weather. Renewable. These systems can covert up to 90% of the energy of water into electric energy, which is an astonishing number. Most forms of hydropower are very environmentally friendly. It produces carbon dioxide and other pollutants. Answer: C. It harms aquatic organisms.
