Q90 . Trade - offs for the zipper resourcese . Large scale hydroelectric powerThis taps the abundant capacity resource presented to humanity by spirit in the form of weewee streams flowing under dominance vigor gradient presented by natural topography . This zilch resource is practic entirelyy free , practically renewable and exploiting this form of goose egg hurts the environs to the minimal extent . We asshole term it as green push . This form of cogency is very positive of economic development in remote and hilly terrain , where it is non easy to transport other forms of energyThis has disadvantages and limitations too . Construction of hulking dam required for large hydroelectric power in many cases leads to rehabilitation of a large population . A large dam (water mass ) may lead to unduly high pressure on the tectonic plates and cause res publica quakes with disastrous consequences . Besides , such plants have to be constructed in remote and hilly terrains , which is not an easy task in itself . Operation of the plant is made difficult by the back up that comes with the flowing water during rainy seasonf . Passive solar powerThis converts solar energy into useful form of energy say light up which locoweed be utilized for room heating , water heating etc . This is renewable or non exhaustive form of energy . This is highly eco friendly or green form of energy . This is distributed form of energy in the sense that this is consumed where it is produced , therefore , issues pertaining to energy transportation is not at all there . The features for exploiting can be designed in a building during wrench or even retrofitted afterwardsWhat we get is heat only , which is not very useful form of energy . This is highly localise and can not be transported . This is not useful during dark . It is not so easy to incorporate features for exploiting this form of energy in an existing building .

This is not at all useful for those regions devoid of ample cheerfulnesslightg . Active solar powerThis converts solar energy into electrical energy by using photovoltaic cells . This is also renewable or non - exhaustive form of energy . This is green or eco friendly form of energy . This can be stored using batteries . This is also highly distributed form of energy as an combat-ready solar panel can be made of each household . This is working even when sun is not there i .e . during night or mucky hours as the electrical energy can be stored in batteriesThe disadvantages are very low conversion efficiency of solar energy into electrical energy . Small scale of solar power plants large scale plants are yet break down a reality and therefore , limited applications Besides , hepatotoxic materials are required for construction of photovoltaic cells required for active solar powerh . Wind PowerThis converts energy of naturally flowing tune current or wind into electricity . This is also renewable or non - exhaustive form of energy This is green or eco friendly as it causes no harm to nature . This is open on large and...If you want to get a teeming essay, order it on our website: Orderessay
