Energy and exergy analyses of a spark-ignition engine
In this paper, the performance of an internal combustion engine is evaluated at the steady-state condition by application of energy and exergy analysis using the experimental test results. The energy and exergy balances are calculated at different engine speeds. The results show that the heat rejection of energy and exergy flow increases with increasing engine speed. The exergy efficiencies are ...

E-commerce, paper and energy use: a case study concerning a Dutch electronic computer retailer
Impacts of the application of e-commerce on paper and energy use are analysed in a case study concerning a Dutch electronic retailer (e-tailer) of computers. The estimated use of paper associated with the e-tailer concerned was substantially reduced, if compared with physical retailing or traditional mail-order retailing. However, the overall effect of e-tailing on paper use strongly depends on ...

Thermodynamic analyses of closed thermochemical energy storages
Thermal Energy Storage (TES) is an important technology for achieving more efficient and environmentally acceptable energy systems. Where space is limited, thermochemical TES has the highest potential to achieve compact thermal energy storage. Here, a general closed thermochemical TES is investigated using energy and exergy analyses. An illustrative example is presented, and the energy and exergy ...

Models of energy saving systems: the battlefield of environmental planning
Traditionally, energy planning has been interpreted as planning for an appropriate energy supply system, based on a crude prognosis for the energy demand. Over the past couple of decades, however, the immense possibilities of regulating energy demand - and the benefits of doing it - have become increasingly recognised and also partly included in the planning. This paper first describes some ...

Global bioenergy: problems and prospects
This paper explores the future global potential for bioenergy. We use energy analysis, and more generally climate change effects, as our criteria for evaluation. Since widespread use of new bioenergy is probably decades away, our evaluation attempts to take into account likely future conditions. Previous research displays large variations in estimates of both energy ratio and technical potential. ...
