Due to the water cycle, the availability of water to generate electricity is almost endless. Which of the following is the largest disadvantage of hydropower? Q1-Which of the following is a disadvantage of renewable energy? 10 Advantages and Disadvantages of Hydroelectricity. According to the 2019 Hydropower Status Report, hydroelectricity gave us a whopping 21.8 GW of energy and grew by 9% over the year. Explanation: The hydropower is a one of the most commonly used in the world. This can be harnessed through the construction of dams across rivers. Which of the following is a disadvantage of this plan? Hydropower is completely renewable, which means it will never run out unless the water stops flowing. It could cause flooding and displace wildlife. Hydropower is a nonrenewable resource. Environmentally friendly. Renewable. Answer: C. It harms aquatic organisms. Advantages of Hydropower. Hydropower is the most widely used renewable energy technology. These systems can covert up to 90% of the energy of water into electric energy, which is an astonishing number. As a result, hydro plants are built to last. Hydropower is a natural form of energy that harnesses the sea’s tides or the motion of rivers. Surface mining _____. Renewable energy sources _____. Answer : The disadvantage of using hydropower is Land can be flooded, displacing people and wildlife. moving air. In hydropower, electricity is generated using the mechanical energy of moving water. Hydropower systems are very efficient because of the density of water, the force of gravity and the technological advantages of today. 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 relies on wind activity, so power could change with the weather. Dams release harmful chemicals and toxins. 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 One of the effective methods of producing power is through the use of streaming or falling water. Most forms of hydropower are very environmentally friendly. Two primary disadvantages of hydroelectric power include the high investment cost and its reliance on precipitation. ... Hydropower uses the kinetic energy of water to generate electricity. Hydropower depends on time of day. It … It produces carbon dioxide and other pollutants. Explanation : Hydropower is a renewable source of energy. A local town proposes switching to hydropower for its electricity needs. Advantages of Hydropower: Hydro power is a very efficient source of renewable energy. Advantages and disadvantages of hydropower schemes can be listed in terms of economic, social and environmental aspects. The main advantages of this type of energy are: 1. User: Which of the following is the largest disadvantage of hydropower?Dams negatively impact the environment. The advantages of Hydropower are summarized below: 1. 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. It is a mature technology and its strengths and weaknesses are equally well understood. Aug 3, 2018 Jul 8, 2018 by Editor in Chief. Their fast response times enable For this reason, hydropower is a renewable energy source with high energy efficiency. It is a new type of power that other towns have not tried.
