A brief note on the historical evolution and present state of exergy analysis
As social concerns increasingly focus on energy production and energy systems, it is important that scientists and engineers continue to innovate and improve current methods. Aiding scientists and engineers is a relatively new tool known as exergy analysis, which focuses on the optimal work done while bringing a system into equilibrium with an environment (it is the maximum work for power ...

Extended Exergy Accounting as a general method for assessing the primary resource consumption of social and industrial systems
The method of Extended Exergy Accounting (EEA) is proposed as a paradigm for the evaluation of the equivalent primary resource consumption of 'Energy Systems'. In a 'system's approach', an energy system is an assembly of components that feed on primary energy sources to produce material or immaterial commodities.Keywords: extended exergy accounting, EEA, thermoeconomics, resource consumption, ...

Potential of energy production by Chinese farmers to fuel rural development
The role of farmers as future energy producers of China is explored within a fast changing rural economy. Data on rural households energy demand, socio-economic and environmental data are used from a household survey with a geographical spread over China. A concept of a more flexible energy production system, i.e., Biomass-Based Distributed Polygeneration (BB-DPG) is introduced. Through a more ...

Application of artificial neural network to model the energy output of dairy farms in Iran
An artificial neural network (ANN) model was developed to assess the energy input–output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input–output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden ...

Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica
Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

Thermal Treatment Of Halogenated Inorganic Aqueous Waste With Energy And By-Product Recovery
This paper describes the incineration technology used to safely destroy the liquid and gaseous wastes containing inorganic salts generated by Bulk Pharmaceutical and agrochemical industries. The plants are supplied with dedicated downstream Air Pollution Control System (APC) or energy recovery where applicable. Due to the emergence of new products and increased production in Pharmaceutical and ...

The 1TW EU Solar Pathway for 2030
Recently, the development of renewable energy sources has become an urgent need due to the Russian-Ukrainian conflict, which has led to energy shortages in Europe. European Commission Vice President Frans Timmermans has proposed an energy strategy that aims to separate Europe from Russian gas as soon as possible, while protecting citizens from painful and increasing energy price shocks. ...

A closer look at Energy Demand in the UK.
The consumption of energy in the UK and Europe has experienced a gradual decrease in recent years. Despite this positive trend, there are numerous daily activities that could be accomplished with reduced energy usage. In our previous publication, we delved into the sources of energy and electricity production systems. In this article, we shift our attention towards the electricity consumption ...

Environmental assessment of energy production by combustion of biogas provided by the anaerobic digestion of agricultural biomass
This paper tries to compare the environmental impacts of energy production using agricultural biomass and energy production using traditional reactor systems (natural gas and fuel oil) by using the Life Cycle Assessment (LCA) methodology. In order to make this comparison, the impact assessment methods CML 2 BASELINE 2000 (problem oriented method) and ECOINDICATOR 99 (damage oriented method) are ...

Energy-sensitive control strategies for decoupled production systems
Rising demand for energy caused by emerging economies, decreasing oil stocks, and the intended nuclear phase-out in some industrial countries has led to new problems concerning sufficient and on time energy supply. Since availability of energy has a dramatic influence on production, energy has to be considered a process prerequisite instead of a production-related overhead topic, as usually ...

Regional geological recognition for the implementation of a urban geothermal concept
A reflection seismic survey was performed in the city of Lausanne (CH) to map geological layers relevant to geothermal energy production. By using a wireless seismic system and a powerful seismic vibrator source we were able to high quality results despite the presence of elevated urban noise levels. The new subsurface maps allow the estimation of the geothermal potential for the city of ...

Value stream mapping based on energy and cost system for biodiesel production
Organisations have to give more attention to customer demands for survival and also for increasing their market shares. But customers' demands are not stable. The main problem of all organisations is how to cut costs during production process. The solution to this problem is built up with lean–based production systems. Value stream mapping identifies those areas where unwanted productivity is ...

Multi-component self-consistent nuclear energy system: protected plutonium production (P3)
The research activity on Protected Plutonium Production (P3) has been performed in the framework of MC-SCNES that simultaneously achieves four requirements – energy production, fuel production, burning of radioactive wastes and safety by the combination of fission, spallation and fusion neutron sources. The increase of a fraction of 238Pu provides an essential protective measure to plutonium ...

Assessing the benefits of a provision of system services by distributed generation
Distributed Generation (DG) units are said to have the potential to become an integral part of the future power systems. Today, DG units are characterised by high specific investment costs, but nevertheless are politically promoted because of their high degree of energy efficiency and their capability of reducing the current dependency on fossil fuels. However, at longer term DG units have to ...
