Within recent years, energy policies have imposed a number of targets at European and national level for rational use of energy (RUE), renewable energy sources (RES) and related CO2 reductions. As a result, a wide variety of policy instruments is currently implemented and hence the question...

Bioenergy is an important energy source for Tibetans. To compensate for the lack of a comparative study on household bioenergy consumption and CO2 emissions among farming region, farming-pastoral region, pastoral region, and forest edge zones in Tibetan area, the authors conducted the...

The results of a survey are presented describing the attitudes of Australian tourists to micro-generation renewable energy supply (RES) for hotel accommodation. The average positive response rate to all questions was above 50%, implying a desire by tourists for environmentally friendly...

The results of a survey describing the attitude to renewable energy supply (RES) amongst tourism accommodation providers in Queensland, Australia, are presented. A 65% response rate was achieved. Results showed that 9.2% of respondents had some form of RES, and that the majority of operators...

This study explores the scope for increasing the contribution of woody biomass for private space and water heating in the North East Scotland, which corresponds to the administrative districts of Aberdeen, Aberdeenshire and Moray. It assesses the potential benefits in terms of carbon dioxide...

The energy demand of the hotel sector of an Italian region is here utilized for hierarchizing, by means of an empirical method, efficient measures devoted to energy saving and reduction of CO2 emissions.

The objectives of this study are to present a model for biogas production systems to help achieve a more cost-effective system, and to analyse the conditions for connecting combined heat and power (CHP) plants to the biogas system. The European electricity market is assumed to be fully...

Feedstock supply is one of the key obstacles for cost-effective production of cellulosic biofuels. This paper proposes an assessment model to study the feedstock costs, energy consumption, and CO2 emissions associated with collecting and transporting cellulosic biomass from farm to storage...

To fully model the anaerobic digestion process, biological and physico-chemical background, the kinetics of bacterial growth, substrate degradation and product formation have to be taken into account. The presented approaches differ depending on the requirements and the developer of the model....

Biomass is becoming a more and more interesting option to replace conventional fossil fuels for heat and power generation. Small plants able to use solid biomass, collected in the plant neighborhoods, are having a growing diffusion: University of Pisa jointly with some local manufactures has...
