ENERGY ANALYSIS OF A SOLAR BLIND CONCEPT INTEGRATED WITH ENERGY STORAGE SYSTEM

Niaparast, Shervin January 2013 (has links)
The use of an attached sunspace is one of the most popular passive solar heating techniques. One of the main drawbacks of the sunspace is getting over heated by the sun energy during the hot season of the year. Even in northern climates overheating could be problematic and there is a considerable cooling demand. Shading is one of the most efficient and cost effective strategies to avoid overheating due to the high irradiation especially in the summer. Another strategy is using ventilation system to remove the excess heat inside the sunspace. However this rejected energy can be captured and stored for future energy demands of the sunspace itself or nearby buildings. Therefore the Solar blind system has been considered here for the shielding purpose in order to reduce the cooling demand. By considering the PV/T panels as the solar blind, the blocked solar energy will be collected and stored for covering part of the heating demand and the domestic hot water supplies of the adjacent building.  From a modeling point of view, the sunspace can be considered as a small-scale closed greenhouse. In the closed greenhouse concept, available excess heat is indeed utilized in order to supply the heating demand of the greenhouse itself as well as neighboring buildings. The energy captured by PV/T collectors and the excess heat from the sunspace then will be stored in a thermal energy storage system to cover the daily and seasonal energy demand of the attached building. In the present study, a residential building with an attached sunspace with height, length and width of 3, 12 and 3.5 meters respectively has been assumed located in two different locations, Stockholm and Rome. Simulations have been run for the Solar blind system integrated with a short-term and a long-term TES systems during a year to investigate the influence of the sunspace equipped with a PV/T Solar blind on the thermal behavior of the adjacent building. The simulated results show that the Solar blind system can be an appropriate and effective solution for avoiding overheating problems in sunspace and simultaneously produce and store significant amount of thermal energy and electricity power which leads to saving considerable amount of money during a year.

Rural electrification using renewable energy resources - Case Study of Rayal, Nepal : Minor Field Study

Beck, Madeleine, Schött, Cecilia January 2013 (has links)
This study has been conducted as a Minor Field Study (MFS) and focuses on the electrification process of Rayal, a remote village in the Far Western Development Region of Nepal. The purpose of the study was to investigate the possibilities of providing electricity based on renewable energy resources to Rayal, both from a technical and a socio-economical point of view. Preliminary research in Sweden was complemented by a field study in Rayal between February and April 2013. Wind power, solar power and micro hydro power were investigated as potential sources of energy. Wind power was considered as unsuitable, due to the low wind speeds in the village as well as poor infrastructure in the country. Solar power and micro hydro power were both calculated based on three different demand scenarios. The results indicate that, depending on the demand and paymentability of the villagers, both solar and micro hydro power could be considered as good options. Solar power is, however, only economically feasible for covering the basic needs of lighting. At higher loads micro hydro power is more economically viable. Excess electricity could be utilized by community facilities, to improve education and health. Alternatively, it could be used to power electrical agricultural equipment which could improve productivity and hence stimulate economic growth in the village. / Denna studie har utförts i form av en Minor Field Study (MFS) och fokuserar på hur en elektrifiering skulle kunna ske av Rayal, en avlägsen by i Far Western Development Region i Nepal. Syftet med studien är att undersöka vilka möjligheter som finns för att elektrifiera Rayal med hjälp av förnyelsebara energikällor, både ur ett tekniskt och från ett socio-ekonomiskt perspektiv. De tre olika teknikerna som har undersökts är vindkraft, solkraft samt småskalig vattenkraft. Vindkraft har uteslutits som lämpligt alternativ, på grund av för låga vindhastigheter i byn, samt bristande infrastruktur i Nepal. Solkraft och vattenkraft har undersökts utifrån tre olika behovs-scenarion. Resultaten visar att, beroende på efterfrågan och betalningsförmågan hos byborna, kan både sol och småskalig vattenkraft betraktas som lämpliga alternativ. Solkraft är dock endast ekonomiskt försvarbart vid mindre projekt, som täcker det grundläggande behovet av belysning. Vid ett större behov är småskalig vattenkraft en mer ekonomisk lösning. Detta ökade behov skulle till exempel kunna vara samhällsförbättrande anläggningar, för att höja utbildnings- och hälsonivån. Ett annat ökat behov skulle kunna vara elektriskt drivna jordbruksmaskiner för att förbättra produktiviteten och därigenom stimulera den ekonomiska tillväxten i byn.

A legal framework for the promotion of renewable energy in South Africa through fiscal instruments / Michél Coetzer

Coetzer, Michél January 2014 (has links)
South Africa‟s current energy sector places undue reliance on fossil fuels to fulfil the country‟s energy requirements. The use of these non-renewable energy resources are unsustainable, as millions of tonnes of harmful emissions are released and estimates are made that these resources will be depleted within the next 100 years. Therefore the country has to source alternative energy resources. Renewable energy resources (for example solar energy) are considered to release little or no harmful by-products and have an infinite supply. Therefore the South African government has to promote the use of renewable energy as part of its commitments to address climate change and to ensure sustainable energy resources. Some of the most popular regulatory tools that a state uses to control human behaviour, is through command-and-control instruments and fiscal instruments. The latter promotes behavioural changes by rewarding desired behaviour which ultimately advances the user‟s own best interest. Because of the nature of renewable energy governance, energy users can not be forced or compelled through commandand- control instruments to use renewable energy. They should rather be encouraged or persuaded to use this form of energy through market-based instruments. This is also the central hypothesis of this dissertation. The purpose of this study is to determine the extent to which the South African legal regime makes provision to promote the use of renewable energy resources through fiscal instruments. Therefore the various energy-related white papers, policy papers and legislation will be analysed. This study found that South Africa‟s legal regime only partly makes provision to promote the use of renewable energy resources through fiscal instruments. The policy part of the legal regime is fairly well developed, but the statutory regime lacks detail and in its current form, environmental/energyrelated legislation does not fully correspond with the lofty objectives of the policy framework. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2015

Endependence: renewable energy in a rural community / Independence: renewable energy in a rural community

Schuette, Krystal M. January 1900 (has links)
Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Mary C. Kingery-Page / Rural Kansas communities are almost entirely dependent on large energy corporations. These corporations, in turn, are almost completely dependent on fossil fuels for energy production. Three major implications exist within these dependencies: 1) the dependence of rural communities on large corporations reduces the potential of a local economy to support itself; 2) the dependence on fossil fuels has severe environmental impacts; and 3) fossil fuels are non-renewable resources and will inevitably be exhausted. A rural Kansas community has resources necessary to achieve and maintain energy independence in a renewable manner. The design of these systems in regard to economy, society, aesthetics, technology, and ecology will play a key role in sustaining these resources into the future. The intent of the project is to create a tool for rural communities to evaluate localized renewable energy potential using Washington, Kansas as an example. Several questions were addressed to determine the capacity and feasibility of each local energy resource: What renewable energy resources are available to a rural Kansas community and are they sufficient for the community to achieve energy independence? How can the resource or its production be designed and maintained in regard to its environmental impact and long-term viability? What are the implications of energy independence for the community’s identity? Because each question is dependent upon the answer to a previous question, a decision tree was the most viable method for the project’s analysis and development. Research into the technology and science associated with each resource provided a general knowledge of the definitions associated with and processes necessary to determine the feasibility of the resource. For resources receiving a positive feasibility rating, analysis continued with a basic cost/benefit analysis that compares potential costs involving implementation and maintenance with the payback, offsets, and incentives involved in utilizing each resource. Analysis of each feasible resource continued with site suitability analysis. The analysis of each resource resulted in resource maps showing potential implementation locations for three renewable resources studied: hydro, wind, and solar. The maps and accompanying graphics communicate the integration of renewable energy technologies into the existing community’s identity.
