The presented paper is a techno-economic feasibility study to use solar energy as a renewable energy to power the Passive Optical Network (PON). This discussion focuses on the requirements and sources of power for the active components of optical access networks. To ensure continuous reduction of the carbon footprint while advancing towards purely passive optical networks, we have emphasized th...

Techno-economic analyses (TEAs) of CO 2 capture technologies have risen in popularity, due to growing interest meeting emissions reduction targets. Adsorption processes are one the proposed for capture, and although difficult, standardization TEAs adsorption should be attempted. The reason is that often referred as input data other forms modeling, guide policy, act summaries those unfamiliar wi...

Via a detailed analysis and review of the currently available literature, this work aims at clarifying the phenomena, physical and mathematical, underpinning the methodologies and results in forest bioenergy carbon accounting. The large scale techno-economic models indicate that an increased forest stemwood removal for bioenergy purposes may cause either a decrease of the forest carbon stock (o...

Introduction Improvement of the energy industry in developing countries is the major basis of the process of techno-economic and socio-cultural development. This improvement requires the transfer of energy technology which is dominated by non-renewable energy systems. Natural resources which are mostly non-renewable, on the other hand, face various threats caused by such a process of developmen...

Ethanol produced from various lignocellulosic materials such as wood, agricultural and forest residues has the potential to be a valuable substitute for, or complement to, gasoline. This paper reviews the research activities in Sweden on development of the technology for ethanol production from lignocellulosics. The paper focuses on hemicellulose and cellulose hydrolysis and fermentation as wel...

A techno-economic heating energy system model for Vienna (Austria) is developed. Based on an existing solar potential map, different solar heat strategies can be evaluated economically and ecologically. The resulting share of installed solar heat units for every building is displayed in a 3D city model. This 3D model allows city planners to study the spatial impact of these strategies. Results ...

This article examines Philip Reeve’s novel for children, Mortal Engines, and M.T. Anderson’s young adult novel, Feed, by assessing these dystopias as prototypical texts of what Ulrich Beck calls risk society. Through their visions of a fictional future, the two narratives explore the hazards created by contemporary techno-economic progress, predatory global politics and capitalist excesses of c...
