Hydroelectric power generation: Himachal pradesh's perspective

Since the inception of civilization man has been involved in making his life smoother and comfortable. And in search of better living he has categorized the available natural resources in two categories i.e. renewable and non-renewable. Renewable simply stands for the energy which derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and bio fuels and hydrogen derived from renewable resources. Global scenario of the renewables is not that much satisfactory, about 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and bio fuels) accounted for another 3% and are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity and 3% from new renewables. While on the other hand, non-renewable resources are those resources that cannot use again, once they are exhausted, they will be exhausted forever. World with increasing population cannot rely upon on one aspect of these resources and a proportionate balance between both could be better option. Hydro power because of its abundance availability round the globe is the preferable choice of many developing and developed economy round the globe. Hydro water is one of the main and globally harnessed renewable sources. It is a flexible source of electricity since plants can be ramped up and down very quickly to adapt to changing energy demands. However, damming interrupts the flow of rivers and can harm local ecosystems, and building large dams and reservoirs often involves displacing people and wildlife and requires significant amounts of carbon-intensive cement. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. The electrical power generated through the use of the gravitational force of falling or flowing water is known as hydroelectricity.
