Renewable energy provides twenty percent of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It is a renewable source of energy and provides almost one-fifth of electricity in the world. Also, it generates electricity using a renewable natural resource and accounting for six percent of worldwide energy supply or about fifteen percent of th...

Assuming that interest groups, like households, firms, or any other structured organization, have limited resources but broad objectives, how do they pick and choose which regulatory battles to fight? The issue of interest group battle choice has received little direct attention in the literature, in large part because defining the state space of total interest group activity is often difficult...

A very large hydroelectric generating project has been proposed for the northern regions of Quebec. Numerous benefits will be derived from this project: inexpensive power, reduced pollution, and improved quality of life. The native peoples living in the region object strongly, however, and claim that the project will destroy their culture. A 35-minute video describes this conflict and challenge...

The usage of regenerable low power sources is currently rather reduced. Utilization of some specialized softwares of SCADA type allow the operation of the low-power hydroelectric power plants in automatic regime, without local monitoring personnel, these being able to be remotely monitored and controlled. In this way, the utilization of such power plants becomes profitable. A special importance...

This paper aims at estimating the efficiency of hydroelectric power plants (renewable energy resources) and thermal power plant (non-renewable energy resources) in Iranian provinces. Data Envelopment Analysis (DEA) approaches is applied to estimate the efficiency. The network is modeled as a linear system with multiple inputs and one output. Fuel cost, labor force, operation cost are used as in...

In utilities using a mixture of hydroelectric and nonhydroelectric power, the economics of the hydroelectric plants depend upon the reservoir height and the inflow into the reservoir for several days into the future. Accurate forecasts of reservoir inflow allow the utility to feed proper amounts of fuel to individual plants, and to economically allocate the load between various non-hydroelectri...

it is expected that, compared with other power plants, changes in fuel cost for power plants in the deregulated electricity market leads to changes in the generation capacity of wind power plants. to quantify this effect, this article aims at modeling energy generation capacity and supply or distribution of different power plants as opposed to those of wind power plants. the proposed model was ...

Nowadays, it is important to consider environmental issues, as ecological problems and their severe effects are intensifying in Iran, particularly in Khuzestan province. The environmental effects of hydroelectric plants are highly regarded due to their significant impact on an extensive area. Lack of safe path for fish passing through the turbines is one of these damages. In order to deal with ...
