In this paper a step-by-step approach is presented for the adoption of technologies designed to exploit hybrid renewable (solar, wind, biomass and small hydro) energy Systems at the rural level. It is centered around the establishment of rural energy centers to improve the basic living environment. In due course, the role of these centers is to be expanded to encompass agricultural, domestic, t...

This paper presents a developed method for controlling multi-renewable energy generators. The control system depends basically on three sensors (wind anemometer, solar sensor, and voltage sensor). These sensors represent PLC’s analogue inputs. Controlling the output voltage supply can be achieved by an enhanced method of interlocking between the renewable energy generators, depending on those s...

The energy demand is sharply increasing due to industrialization, huge population growth, and increased comfort lives etc. This energy demand mostly extracts from the fossil fuels which is non-renewable and the known reservoirs expected to finish in near future. The whole world may face energy crisis soon, altogether the fossil fuel produces greenhouse gasses (GHG) which cause the climate chang...

Recently, environmental issues have been the focus of much of the world’s attention. This has stimulated a response in many countries, which has led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for: heating, lighting, cooling, venti...

Recent studies have shown that the Information and Communication Technology (ICT) industry is responsible for about 2% of the global emission of CO2 and this percentage is expected to increase as the internet expands in bandwidth and reach. In this paper we propose a hybrid-power IP over WDM network where renewable energy is used to reduce the CO2 emission of IP overWDM networks. ALinear Progra...

Conventional energy sources based on oil, coal, and natural gas have proven to be highly effective drivers of economic progress, but at the same time damaging to the environment and to human health. Keeping in mind, the social, economical and environmental effects of renewable energy system have been discussed in this paper. The uses of renewable energy system, instead of, conventional energy s...

Nowadays energy is one of the most essential needs of human being and it can be considered as the basic prerequisite of social and economic development.  Hence, many of the correlations and legislations of a country are affected by it. Since Iran has huge source of gas and oil, it has turned to a fossil fuel oriented county. But as oil and gas sources are non-renewable ones and cannot be replac...

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 literatur...
