In current research, energy efficiency and technical efficiency of wheat farmers were calculated in Mazandaran province. To estimate technical efficiency the Stochastic Nonparametric Envelopment of Data (StoNED) was used. The model incorporating nonparametric data envelopment analysis model which contain the smoothness and concavity constraints with stochastic frontier analysis model. The requi...
This paper investigates the potential of Romanian renewable energy across energy production and consumption definitions. Moreover, it presents a model that estimates the regional evolution of renewable energy diffusion, focusing primarily on hydro energy. Statistics showed that Romanian consumers have a key role in developing the renewable energy market, while it is also very important to ensur...
Today, the agricultural sector is heavily dependent on energy to meet the growing demand of worldchr('39')s growing population food. This study aims to determine energy indices and equations based on its energy consumption and production. 380 farmers out of total number of 31190 irrigated wheat farmers of Isfahan were selected across the 24 borough of the province (based on Cochranchr('39')s r...
Global discussions involving the enhancement of renewable energy use frequently highlight the European Union “Triple 20” deal as the main large-scale effort aimed at changing the worldwide pattern of fossil fuel consumption to power economic activities. Actually, the targets of carbon emissions reduction and increase in the use of renewable energy before 2020 symbolize an extraordinary attempt ...
Demand for renewable energy in electric power systems is growing as fast. Reasons, including the desire of countries to increase production capacity of wind power are the great advantages of this method production of electrical energy. Because wind energy is many, renewable and clean. Refer ences R . Billinton, R. N. Allan ,”Reliability Evaluation of Engineering Systems”, 2nd Edition, Plenum Pr...
research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...
in the science of operation research and decision theory, selection is the most important process. selection is a process that studies multiple qualitative and quantitative criteria, related to the science of management, which are mostly incompatible with each other. the multi criteria selection of a renewable energy portfolio is one of the main issues considered in multi criteria literature. i...
Renewable energy policies address two market externalities at the same time as they (1) internalize the environmental cost of conventional energy production (GHG emissions and air pollution) and (2) appropriate earnings from learning-by-doing in the renewable energy
The rules of a number of electricity markets encourage renewable energy production and demand response through fixed support schemes and socialize the costs of integrating this production trough grid tariffs. These mechanisms are not economically efficient because they do not rely on market-based prices and do not consider the actual costs of achieving reliable system operation. This paper pres...
This paper discusses the perspective of renewable energy (wind, solar, wave and biomass) in the making of strategies for a sustainable development. Such strategies typically involve three major technological changes: energy savings on the demand side, efficiency improvements in the energy production, and replacement of fossil fuels by various sources of renewable energy. Consequently, large-sca...
