To meet rising targets for renewable-derived electricity generation, wind power is currently the preferred technology. However, it is widely accepted that due to the stochastic nature of wind, planning restrictions and the finite availability of suitable sites there is an upper limit to the...

Renewable energy sources (RES) are mainly used in the electrical sector. Electricity is not a storable commodity. Hence it is necessary to produce the requested quantity and distribute it through the system in such a way as to ensure that electricity supply and demand are always evenly balanced....

The importance of the pattern of energy production, conversion and consumption in ensuring sustainable development necessitates stock taking of national energy supplies and demands so as to enable adequate policy formulation. In this paper, the state of energy resources, supply and demand in...

It is a common practice, in Korea as well as other countries, to use economic feasibility study for policy-maker or business communities before deciding substantial investments on sustainable energy projects especially photovoltaic industry in 2008.

In this paper we analyze the main available data related to the geothermal system of Ischia Island, starting from the first geothermal exploration in 1939. Our aim is to define a conceptual model of the geothermal reservoir, according to geological, geochemical, geophysical and stratigraphic...

In this study major agricultural residues of Turkey were identified and characterized as a potential fuel source for electric power generation. The environmental cycle for impacts of biomass utilization were investigated in comparison to Turkish lignites. Based on the total production of cereals...

This study was carried out in response to the growing interest on household biogas digesters in Latin America, particularly in rural Andean communities. The aim was to compare the fixed dome and plastic tubular digester in terms of biogas production, cost and environmental impact, using the life...

An increasing number of rural municipalities wants to meet their entire energy demand with biomass. This article gives a system analytic view on these “bioenergy villages” by balancing pros (reduction of CO2 emissions) and cons (increasing costs, land use) using the example of a model...

Countries around the world meet their electrical energy demand by utilizing fossil fuel based, nuclear or renewable energy sources. In contrary to fossil fuel based and nuclear energy sources which have negative environmental impacts and which increase energy import dependency, renewable energy...

This paper proposes a computational-statistics based approach for solar radiation reconstruction at sub-hourly intervals. A dimensionless form of stochastic variable, V, which is defined as the difference between the theoretical global solar radiation in clear-sky conditions and the actual solar...
