Biomass gasification systems may be relevant for decentralized power generation from these residues in the isolated areas. This work deals with the analysis of both the technical and economic feasibility, and then the environmental and social impacts of a 95 kWe gasification plant project in order to generate electricity for Badara village in Burkina. Two biomasses feedstock: cotton stalk and rice...
Nowadays the renewable energy implementation and development is being discussed widely in Thailand with its 20-Year Energy Efficiency Development Plan (2011–2030) and additionally the 10-Year Alternative Energy Development Plan 2012–2021 (AEDP 2012–2021), which is targeting on increasing the share of renewable energy and alternative energy uses by 25 percent instead of fossil fuels within the next...
Conventional grid extension has been the predominant mode of electrification in India. However, renewable energy based mini-grids have also been used for providing electricity access in remote areas, forested habitations, and islands. This paper, based on extensive literature review, interview with key stakeholders, and field visits to selected sites, captures the nuances of renewable energy based...
The National Action Plan for Climate Change of India considers renewable energy as a key thrust area. This paper focuses on one such renewable energy source, bioenergy which exists in diverse forms and finds applications in varied energy supply and demand sectors. Two long term scenarios for bioenergy up to 2050, business-as-usual (BAU) and green energy (GE) are assessed using a bottom up energy system...
This paper covers the analysis methods and results of the increasing wind integration impacts on the Baltic region's electricity market participants and power plant economics. The scope of the study is 2025 - when mayor decrease in generation capacities has occurred. The final part of the paper addresses the key findings that large scale wind integration might have on the economics of different generation...
The paper reports on the technical, economic and environmental assessment of stand-alone and grid connected electricity generation from landfill gas in South Africa. Theoretical models are developed in Matlab to calculate the methane production potential of three Western Cape landfill sites in order to assess their suitability for landfill gas to energy (LFGTE) projects. Then Homer package is used...
This research examines optimal operation of microgrid systems. Microgrids are disaggregated from main transmission grid. Microgrids are able to integrate distributed renewable energy, take advantage of waste heat, provide higher power reliability, reduce electricity transmission loss, and decrease greenhouse gas emissions. The study considers solar power, wind power, biomass power, gas turbine, fuel...
Distributed generation can play an important role in the complex portfolio of environmental and climate friendly technologies. Both renewable sources-fueled and fossil-fueled power plants show potentials to increase the overall efficiency of energy systems therefore to mitigate their impact: policy makers have learnt of their importance and now, at local level, the situation seems the opposite of...
Power sector, as the biggest contributor to the total CO2 emission of China, is faced with tremendous pressure and challenge. The transformation of the whole sector based on the technological innovation and/or introduction appears to be indispensable, which is already recognized by domestic government. Many a measure are taken into practice, such as updating the renewable energies development targets,...
We develop a linear optimization model at the state level, and use this model to investigate how policy constraints on greenhouse gas emissions may affect the lowest-cost choices for electricity generation over the next twenty years. The state-level model provides local and regional decision-makers with a basis for understanding the potential impacts of policy changes, and provides a basis for planning...
This document reports the development of a hybrid and autonomous energy model with solar PV panels and a small CHP (combined heating and power production) system whose primary energy source is the biomass. Also it will be presented several rules for to achieve new energy efficiency levels of a service building. This energy model is also a new sustainable paradigm on energy consumption (electrical...
We present a least-cost linear-optimization model of electricity generation using MARKAL that can be applied at the level of an individual state. Our methodology is applied to a case study of the state of Georgia and used to analyze the evolution of its electricity generation portfolio under different efficiency scenarios.
Energy planning through optimization techniques is not a new concept, although different new models have been proposed and used over the last 30 years. Top down versus bottom up models have been analyzed to characterize the studied context, according to the final scopes. Improvements have been added while making (i) the models bigger and (ii) more complicated to catch more details and to understand...
Cordoba is an inland province of southern Spain. This paper presents the quantity of power that will be necessary to install for covering the electrical consumption of Cordoba's population. Multicriteria has been the followed method with selection of criteria and options for the new and renewable energy technologies assessment based on the analysis and synthesis of parameters under the information...
In this paper we present an alternative power supply evaluation model to determine the optimal type of power supply from a sustainable development perspective. The analytic hierarchy process is applied to decide the priority of different types of power supply. The results of the study indicate the gap between goals of sustainable development and current power supply structure in terms of energy security...
This paper explores the issue of sustainable energy from a multi-flux perspective, and has shown clearly that some of the choices being vigorously pursued today, such as bio-fuels, may have significant limits on scalability. While a Bio-Fueled World does not seem to be sustainable, an Inorganically Fueled World, seems to have the potential to be able to scale to meet global needs, without in any way...
