Beginning in 2007, E-Tech’s Chief Engineer Bill Powers began devising practical alternatives to the oil-gas-coal energy projects that are used in the US-Mexico border area. In the long term, Bill seeks to help develop low-carbon energy strategies based on regional and national domestic needs. The first area examined was close to home: the San Diego-Tijuana region. May, 2008: San Diego ...
Working from home is an excellent experience. Tell us about your role as Environmental & Sustainability engineer, what was the most exciting project you worked on? ...
Traditional data envelopment analysis (DEA) models ignore the influence of environmental variables and statistical noise, which may result in biased efficiency estimates. ...
From the viewpoints of climate change, energy security and environmental values, this study investigates public attitudes towards nuclear power in China. The key point of this investigation is attitude analysis, which indicates that the attitudes towards nuclear power are complex and uncertain. ...
For the successful scale-up of microbial fuel cell (MFC) systems, enrichment strategies are required that not only maximise reactor performance but also allow anodic biofilms to be robust to environmental change. Cluster analysis of Denaturing Gradient Gel Electrophoresis community fingerprints showed that anodic biofilms were enriched according to substrate ...
Various actions have been taken by environmental agencies and ethanol producers to promote the environmental sustainability of Brazilian ethanol. ...
Second law and sensitivity analysis of a lignite–fired Thermal Power Plant (TPP) are implemented by using the data obtained from a simulated 245 MWel TPP in Thermoflex simulation software. In this regard, exergy destruction and exergy efficiency of each component of the power plant and power generation, emissions and exergetic performance of the overall TPP is determined. Also ...
This release is a major update to Envido’s previous energy management system, used to facilitate the collection, reporting and analysis of environmental, utility and energy ...
The environmental assessment of various electric vehicle battery technologies (lead-acid, nickel-cadmium, nickel-metal hydride, sodium nickel-chloride, and lithium-ion) was performed in the context of the European end-of-life vehicles directive (2000/53/EC). An environmental single-score based on a life-cycle approach, was allocated to each of the studied battery ...
Based on SE³T, the China Energy Demand Analysis System (CEDAS) and the China Energy and Environmental Policy Analysis (CEEPA) model are developed. The applications of CEDAS and CEEPA show that the theoretical framework of SE³T and its related modelling provide an effective approach to analyse China's energy and environmental ...
This paper mainly discusses the necessity of cost-benefit analysis on biogas digesters, clearly defines some vague concepts during the analysis, tells how to quantitatively analyse the environmental benefits, and affirms the role of the government and the rural families.Keywords: household biogas digesters, renewable energy, cost-benefit ...
It requires the reconsideration of energy efficient and low emission technologies but also the definition of new instruments of analysis. After an overview of the methods available in the literature dealing with multi-dimensional analysis of energy systems, the authors propose an approach based on the use of a composite utility function. Some examples of ...
This paper deals with the application of micro-cogeneration, Micro-Combined Heat and Power (MCHP) (electrical power Keywords: micro cogeneration, internal combustion, experimental tests, MCHP, micro combined heat and power, CHP, electric heat pumps, EHP, energetic analysis, environmental analysis, economic analysis, ...
The agro-ecological aspects and the high yield of vegetable biomass from hemp farming are the factors that indicate a possible interest in this plant from the point of view of energy use, but in order to validate this it is necessary to carry out a Life Cycle Analysis. It is to be observed that the hemp energy resources come from the vegetable biomass used as fuel, or by ...
In small reaction turbines, runaway conditions may cause significant discharge variations and consequently pressure fluctuations. A benchmark analysis based on the hydrodynamic behaviour of the system through computer simulations and experimental tests was developed. Specific unconventional protection devices were selected to control overpressures induced by runaway conditions in ...
Low environmental damage is one of the main justifications for solar energy, especially now that supply security has slipped from public consciousness. In recent years, there has been much progress in the analysis of environmental damages, in particular thanks to the ExternE (external costs of energy) Project of the European Commission. ...
In this context, PSI, in co-operation with ETHZ, analysed environmental inventories for the selected electricity supply systems. Life Cycle Analysis (LCA) was used to establish the inventories, covering the complete energy chains associated with fossil, nuclear and renewable systems. ...
In accordance with the EU directive on landfilling, a tax on putting organic waste into landfills will be introduced the 1st of January 2000, together with a ban on landfilling organic waste by the year of 2005. In addition, results from environmental systems analysis of organic waste management indicate that anaerobic treatment has a low ...
