Kulić Fahrudin 29 September 2016 (has links)
<p>U ovom radu je prezentirana metodologija razvoja modela optimizacije<br />podsticaja proizvodnje električne i toplotne energije u<br />kogenerativnim postrojenjima koja koriste drvnu biomasu kao gorivo.<br />Model optimizacije je razvijen koristeći matematičku metodu<br />linearnog programiranja u kome je maksimizirana ukupna ekonomska<br />korist za raspoloživi iznos sredstava za podsticaje. Model<br />optimizacije je primijenjen na kogenerativna postrojenja u drvo-<br />prerađivačkoj industriji u Bosni i Hercegovini i pokazano da se<br />primjenom modela optimizacije, kroz iterativni proces, mogu odrediti<br />optimalne vrijednosti podsticaja za proizvedenu električnu i<br />toplotnu energiju koji rezultuju u maksimalnoj ukupnoj ekonomskoj<br />koristi za društvo u cjelini.</p> / <p>This thesis presents a methodology for the development of a mathematical<br />model for optimization of the level of subsidies for generating electricity and<br />heat in co-generating plants that use woody biomass as fuel. The optimization<br />model is developed using the mathematical method of linear programming to<br />maximize the total economic benefits for a defined amount of available funds<br />for subsidies. This model is applied to co-generating plants in the woodprocessing<br />industry in Bosnia and Herzegovina and shows that the application<br />of this optimization model can, through an iterative process, determine the<br />optimal levels of incentives for electricity and heat that result in the maximum<br />economic benefits for the society as a whole.</p>

Quantifying methods for an innovation systems analysis of the UK wave energy sector

Vantoch-Wood, Angus Robert January 2012 (has links)
Current proxy indicators of innovation although insightful, tend to provide more relevance in both larger scale markets, (such as in the pharmaceuticals or electronics industry) and for codifiable innovative activity, (such as patents and bibliometrics). These measures could be capitalised on further if a more robust measure of functionality performance that included informal innovative activity could be gained to help assess the overall performance of the system under inspection. This work uses the emerging UK wave energy sector as a primary case study to explore early stage innovation systems through the novel application of network analysis as well as existing innovation systems theory. It was hoped that a clearer understanding of which metrics were related to which system functionality and how representative they were would help to create more robust and transferable measures of emergent system functionality. The question as to whether this increased confidence and insight into system operation could allow for benchmarking comparisons between spatially or socially different emerging innovative networks, such as different countries or stakeholder types was then addressed, as well as wether this could provide a higher level of efficacy to applied policy support? A further goal of this work was to assess the current wave energy sector through these methodologies and provide insightful feedback into activity, potential opportunities and threats present within the system. The main methodological findings show that the novel application of Social Network Analysis provided a strongly correlated and insightful metric of innovative activity however (as with established metrics), there were clearl limitations on applicability and that a ‘one size fits all’ application of methods is not available for any innovation assessment tools. Additionally, many existing metrics used within analysis are often un-clearly defined or presented leaving largely presumptuous levels of interpretation within the final analysis. Sectoral findings showed a range of narratives regarding the sector. Clear prominence of Scotland and higher levels of all system functionality within the country make it a strong performer within the system. Likewise, a lack of coherent and ‘first-past-the-post’ funding policy has produced a ‘gating’ of technology support that in turn has disillusioned many early device developers while pulling out a fortunate few. This ‘Mathew Effect’ within the system may (among other things) leave the sector open to system shocks from outside competition and reduce the level of market entrance due to a perception of unfair or secretive support provision.

Benchmarking domestic gas and electricity consumption to aid local authority carbon reduction policy

Morris, Jonathan January 2013 (has links)
As part of an effort to be a world leader in international efforts in reducing atmospheric carbon dioxide levels, the UK Government has set itself ambitious targets to reduce carbon dioxide emissions by 80% relative to 1990 levels by 2050. To meet this target, there is a strong emphasis in reducing carbon emissions from the domestic sector through the reduction of energy consumption in UK households by improving the energy efficiency of the housing stock, and the behaviours of the occupants. The Department of Energy and Climate Change have indicated that Local Authorities in England are potentially to work in partnership with businesses and community organizations to facilitate delivery; and as a promoter of domestic energy efficiency policies. Consultation with 11 Local Authorities across England confirmed that they are lacking a reliable mechanism that can detect areas within their administrative boundaries that are most in need of intervention to improve the energy efficiency of the housing stock. For the year 2008 the regression models demonstrate that geographical variations in the size of the house, median household income, and air temperature account for 64% of the variation in English domestic gas consumption, and that variations in the size of the house, median household income, and proportion of households connected to the national gas grid account for 73% of the variation in domestic electricity consumption. The predicted values from these regression models serve as benchmarks of domestic gas and electricity consumption in England having accounted for household income, house size, house type, tenure, and climatic differences and could be used to identify areas within Local Authorities with higher than expected energy consumption for energy efficiency interventions. These results contribute to the wider academic debate over how best to achieve the overall aims of household CO2 reductions by moving beyond a purely technical or behavioural-based approach to reducing domestic energy consumption.

International politics of low carbon technology development : carbon capture and storage (CCS) in India

Kapila, Rudra Vidhumani January 2015 (has links)
This thesis explores the international political dynamics of developing low carbon technology. Specifically, Carbon Capture and Storage (CCS) technology as a climate mitigation strategy in a developing country context is examined. CCS is a technological solution that allows for the continued use of fossil fuels without the large amounts of associated CO2 emissions. This entails capturing the CO2 emitted from large point sources, such as a coal-fired power station, and transporting the captured emissions to be injected and stored permanently into geological media. Consequently, CCS is a bridging technology that could provide more time for transitioning to a low-carbon economy. A case study of India is used, which is an emerging industrialising economy, and is also the third-largest coal producer in the world. India faces a dilemma: poverty alleviation and infrastructure development to support its billion plus population requires vast amounts of energy, which is predominantly based on fossil fuels. Therefore, it was envisioned that CCS would be a sustainable option, which could enable industrialisation at the rate required, whilst preventing the exacerbation of the negative effects of climate change. However, during the period of study (2007-2010), CCS was not embraced by India, despite there being a growing impetus to develop, demonstrate and transfer the technology. India was reluctant to consider CCS as part of a mitigation strategy, and this thesis focuses on the reasons why. An interdisciplinary approach is used, coupling perspectives from science, technology and innovation studies (STS) with concepts from International Relations (IR) scholarship. This sociotechnical conceptual framework is applied to gain a more holistic picture of the failed attempt to transfer CCS technology to India. Key technical challenges and blockages are identified within India’s existing energy system, which have restricted CCS technology implementation. In addition, the political challenges associated with the rejection of CCS by the Indian Government are explored. Empirical evidence is on the basis of elite interviews, an expert stakeholder survey and relevant documents. Another case study on the Cambay basin is used to further demonstrate the influence of political factors on CCS implementation, even in an area considered to have suitable technical conditions. The outcomes of this study have implications for policy addressing global challenges, especially by means of international cooperation and technological change.

Impact of political institutions on electricity generation outcomes in Sub-Saharan Africa

Ngwane, Zamangwane Beryl 02 September 2015 (has links)
A Research Report Submitted to the Faculty of Humanities In partial fulfillment of the requirements for obtaining the degree of Master of Arts in International Relations / Africa’s wave of democratisation since 1990 has transformed political institutions in the region. But while democracy is a desirable end in itself, considerable doubts remain about whether it is contributing to better development outcomes. This study investigates the impact of political constraints on electricity generating capacity, using cross-national data for 46 sub-Saharan African countries. It tests the hypothesis that institutions that restrain arbitrary executive authority result in higher levels of electricity generating capacity. The hypothesis is informed by the theory of credible commitment. This theory holds that political constraints provide a stable political and policy environment that reduces temptations for governments to renege on their commitments. Credible commitments are especially important in attracting investment with a long gestation period, such as investment in electricity generating capacity. In my method I use a combination of statistical analysis and nested case studies to probe the congruence of these outcomes with my hypothesis. For the nested analysis I use the statistically chosen countries of Rwanda and Kenya, which in themselves conform to the pattern of the hypothesis. My central finding is that the presence of democratic political institutions has led to improved electricity generating outcomes in African states. In this way the study contributes to the understanding of the developmental consequences of democratisation in Africa.

Evolutionary technological change : the case of fuel ethanol in developing countries

Juma, Calestous January 1986 (has links)
This study suggests an evolutionary approach to the analysis of energy technology policy. The approach emphasizes economic fluctuations, technological change and Institutional re-organization through time. The liquid fuel sub-sectors of Zimbabwe and Kenya constitute different technological systems adapted to the production and utilization of different energy forms. They represent different market niches In a techno-economic landscape. Gasoline occupies a central role In the energy budget. The 1973-74 oil crisis created major fluctuations which made it possible to introduce fuel ethanol as an alternative liquid fuel. The process of realising the ethanol niche was largely dependent on the existence of technological options whose technical and financial characteristics allowed them to compete favourably with conventional 1iquid fuels. Niche realization also required the modification of the adoptive terrain to reduce the obstacles to the introduction of the new technological systems. The entire process takes an evolutionary perspective because it involves the generation. selection and retention of technological options under constantly changing conditions. Moreover. the technological systems continue to undergo or require incremental Improvements after they have been installed. Such improvements require the generation of plant-level technical knowledge and often lead to the accumulation of local technological capacity. A glance at the evolutionary path reveals periods of gradual change. punctuated by moments of increased innovations which are often linked to periods of major fluctuations. The process is associated with a complex network of institutional arrangements which are also re-organized either in response to fluctuations or in anticipation of emerging niche opportunities. Institutions play a central role because the process is not random, it is purposive and based on socio-economic expectations. It is precisely this point that led to major differences In the process of niche realization In Zimbabwe and Kenya. although both countries were presented with the same technological options. The study draws a wide range of technology policy and research implications from these differences.

A behavioural view of the decision for capability investments : the solar PV industry in Taiwan

Wan, Kwo-Feng January 2015 (has links)
This research examines the role of framing in the process of decision-making for new capability investments under conditions of policy and technological uncertainty. I argue that framing can explain the decision to exploit current capabilities, but is not sufficient to explain the decision to explore new capabilities. This research discriminates between “frames” and “framing” in the investigation: whereas “framing” is the process of constructing the meaning of the decision problem, “frame” refers to a specific perspective adopted by the decision makers. I develop a three-level research design: the industry-level analysis adopts the approach of eliciting heuristics to identify general patterns. The firm-level examines sources of variation and causal complexity by comparative case analysis. The decision-maker level investigates the influence of senior managers' professional experience using a scenario evaluation approach. Three observations from the case study of Taiwanese solar PV firms: firstly, systematic patterns are found in the process of framing environmental uncertainty and attributing the causes of the decision problem of capability investments. Secondly, whilst differentiated framing exists and corresponds to selective attention; such a difference is not necessarily associated with different choice pattern. Finally, the loosely coupling framing and choices leads to the speculation that the role of deliberate practice, rather than framing has a stronger influence on the decision to explore. This research illustrates that the capabilities investment decision is not a single event but a complex process. While the stylised psychological principles explain the heuristic judgments, the influencing factors of an organisational decision are interdependent and temporally connected in the decision context. I argue that the problem of framing lies in prohibiting the alterative frame. Therefore exploration needs to be deliberately sought by the specially designed practice. This research contributes to understanding the relationship between behavioural view of descriptive analysis and prescriptive view of procedural rationality in the decision- making process.
