Hence, these rivers cannot provide for Hydel Power generation consistently.<\/li>\n<li>Many rivers do not have natural waterfalls and huge capital has to be invested for constructing dams.<\/li>\n<li>The sites suitable for generating hydroelectricity are located away from the consuming centres. As a result a lot of energy is wasted in transmission.<\/li>\n<\/ul>\n<p>Question 22.<br \/>\nEnumerate the factors needed for installing a hydroelectric project.<br \/>\nAnswer:<br \/>\nFactors needed for installing Hydroelectricity Power Projects are:<\/p>\n<ul>\n<li>Mountainous area where waterfalls from a height &#8211; the potential energy of felling water helps the turbine to move.<\/li>\n<li>Permanent supply of water can be ensured by perennial rivers. Hence snowfed rivers of the Himalayas are of great use for the generation of hydropower.<\/li>\n<li>Climate should be suitable i.e. rivers should not freeze during winter.<\/li>\n<li>Water of the river should be silt free or water should be stored in artificial reservoirs before releasing in hydel channle.<\/li>\n<li>A gorge between the two hills is the most suitable site for building dams.<\/li>\n<li>Flow of water should be uniform in the river. Any fluctuation would affect the generation of electricity.<\/li>\n<li>There should be enough scope for electricity supply i.e. an industrial zone so that the loss of electricity is minimum in transmission.<\/li>\n<\/ul>\n<p>Question 23.<br \/>\nHow important is the hydel power projects for India?<br \/>\nAnswer:<br \/>\nIndia being so rich in water resources, there is enough importance of developing hydel power projects for India.<\/p>\n<ul>\n<li>Permanent supply of water can be ensured by perennial rivers. Hence snowfed rivers of the Himalayas are of great u$e for the generation of hydropower.<\/li>\n<li>In Deccan, the river flowing through the plateau is very swift and there are many waterfalls in the way, so this helps in power generation.<\/li>\n<li>India has vast arable land and it is in constant need for irrigation due to irregular rainfall.<\/li>\n<li>There are many areas rich in mineral resources along with ideal sites for construction of dams. Thus, it serves the dual purpose by supplying hydroelectricity to the industries as well as helping in promoting agricultural and industrial development.<\/li>\n<\/ul>\n<p>Question 24.<br \/>\nHow do hydel power projects score over thermal project?<br \/>\nAnswer:<br \/>\nHydel Power Projects Score Over Thermal Power Project:<\/p>\n<ul>\n<li>Hydel power is inexhaustible and renewable source of power whereas coal &#8211; the major factor in thermal power &#8211; is exhaustible and non-renewable.<\/li>\n<li>It is cheaper to build the dams than building thermal power stations.<\/li>\n<li>Hydel power projects do not cause any pollution whereas thermal power plants find it difficult to get rid of wastage.<\/li>\n<li>It is easy to transport it for long distances while are restricted to areas of coal production.<\/li>\n<\/ul>\n<p>Question 25.<br \/>\nWhat are the main disadvantages of H.E.P.?<br \/>\nAnswer:<br \/>\nDisadvantages of Hydel Power Projects (H.E.P.) are:<\/p>\n<ul>\n<li>The location is very important for the construction of Hydel Power Projects.
