Hydroelectric dams

Background and context
Dams have existed for thousands of years for various purposes, such as irrigation and flood-control. In the 19th century, they began to be used for hydroelectricity, and by the 20th century, they had become a mainstay of electricity generation. As of 2005, hydroelectric power, mostly from dams, supplied 19% of the world's electricity, and over 63% of renewable energy. Yet, dams have been the subject of significant controversy among environmentalists in recent decades, mainly due to the..............etc

generation of hydroelectric power

INTRODUCTION
The potential for generation of hydroelectric power using the Jhimruk river was identified as early as 1960 by late Tony Hagen. Nepal electricity authority studied the project in 1980’s and produced a feasibility study in July 1987. HMG of Nepal the requested funding for Jhimruk Hydro Electric project from NORAD through NGO’s like UMN / BPC. A project agreement was then signed between HMGN and UMN on 23 Feb, 1989.

What is HEP
HEP (Hydroelectric Power) is an environmentally friendly way to generate electricity.
How it works
A dam is built to trap water, usually in a valley where there is an existing lake.Water is allowed to flow through tunnels into the dam,to turn turbines and thus drive generators.Notice that the dam is much thicker at the bottom than at the top,because the pressure of the water increases with depth.
A picture of how it works
Where is the bes..............etc

Pumped hydroelectric and compressed air energy storage (CAES) are currently economic for utilities when relying on natural geologic formations and the cheapest, most abundant substances (i.e. elevated water and compressed air). In these situations the cost of energy storage capacity can be very low (<$5/kWh1) Unfortunately the scale and location-specific nature of energy storage in natural formations is likely to render it of limited benefit to small scale distributed renewables. Available pumped hydro and CAES capacities could prove small in r..............etc
