Abstract:

The energy generation in Albania is completely from the hydropower plants. In terms of GHG emissions this is 100% green. In Kosovo 97% of energy is generated from lignite fired power plants. Apart the energy generation, the combustion process emits around 8000 ktCO2/yr and 1.5 Mt of ash in the form of fly and bottom ash. In both countries there is no MWh power generated from wind energy, i.e. this energy source is not utilized. Here, a proposed project for five locations in Albania and Kosovo has been analyzed in detail with the aim of installing a 1kW wind turbine off-grid. The method of study is based on the application of RETScreen International program software. This proposed model is intended to replace a base case- a diesel generator with installed capacity 7kW. The locations are selected three in Albania: Vlora, Korça and Elbasan, and two in Kosovo: Prishtina and Prizren. All are in different altitudes. By the calculation of RETScreen program, it has been analyzed the feasibility of the proposed projects by installing a wind turbine at hub’s height 20m. The climate data for each location were retrieved by the RETScreen program from NASA. Generally, the calculation of financial parameters for the investments came out to be positive, the impact of GHG reduction very significant. A 5500 USD investment for the implementation of proposed case showed an equity payback time of 2-3 yrs and GHG reduction of 2.2 tCO2/yr. The electricity delivery to load only from this 1 KW wind turbine resulted to be between 1.6-17 MWh/yr.

Abstract:

This paper is based on a novel approach towards clean energy production, i.e., space innovative applications toward sustainable development. Specifically, the role of Earth observation (EO) satellites in maximizing renewable energy production is considered to show the enormous potential in exploiting sustainable energy generation plants when the Earth is mapped by satellites to provide some peculiar parameters (e.g., solar irradiance, wind speed, precipitation, climate conditions, geothermal data). In this framework, RETScreen clean energy management software can be used for numerical analysis, such as energy generation and efficiency, prices, emission reductions, financial viability and hazard of various types of renewable-energy and energy-efficient technologies (RETs), based on a large database of satellite parameters. This simplifies initial assessments and provides streamlined processes that enable funders, architects, designers, regulators, etc. to make decisions on future clean energy initiatives. After describing the logic of life cycle analysis of RETScreen, two case studies (Mexicali and Toronto) on multiple technologies power plant are analyzed. The different results obtained, when projecting the two scenarios, showed how the software could be useful in the pre-feasibility phase to discriminate the type of installation not efficient for the selected location or not convenient in terms of internal rate of return (IRR) on equity.

Abstract:

The problems of energy, environment protection and ecology play a major role in the development of economy strategy in any country. Most of the traditional power stations operating on organic fuels have a negative impact on the environment. Furthermore, there is a depletion of natural resources due to human activities. One of the ways to solve the problem of environmentally friendly energy production is to use alternative sources of energy. Based on the foregoing, the development of the strategy for the development of traditional and alternative energy must consider environmental and economic factors in a specific country. In the present work it was evaluated the environmental and economic efficiency of application of traditional and alternative energy with regard to the conditions of the Islamic Republic of Iran. The program packages RETScreen which is one of the most effective tools to accomplish the task was used. Calculations of cumulative cash flow from the operation of power plants using different types of primary energy are carried out using models of package RETScreen for assessing the input efficiency of various types of energy sources aiming to cover the intending growth in electricity demands and the environmental assessment with reference to different countries. The results of the study showed that the planning prospects of the development of energy systems in relation to the Islamic Republic of Iran to cover the expected growth in electricity demands it is advisable to use the alternative energy sources, and, first of all, the generating capacity based on solar and wind energy.

Abstract:

This research focuses on proposing and evaluating an optimized hybrid system of wind and tidal turbines operating as a renewable energy generating unit in New Zealand. Literature review indicates increasing worldwide investment in offshore renewable energy in recent years. Offshore energy shows a high potential as an alternative energy generation solution to that of fossil fuels. Using the capacities of wind and tidal power in renewable technologies would be a suitable alternative for fossil fuels and would help prevent their detrimental effects on the environment. It is a cost-effective procedure for the power generation sector to maximize these renewables as a hybrid system. At the design phase, turbine types appropriate to environmental conditions for an area with high wind speed and tidal flow need to be considered. When selecting which turbines should be used, horizontal or vertical axis, number and length of blades, and optimized rotational speed are all important to get maximum capacity from either the wind or tidal energy for the hybrid system. Comprehensive simulation models of the hybrid system are now being set up, using several available commercial software packages such as QBlade, Simulink, and RETScreen. Several different parameters will be required for these simulation models to run in order to test performance, capacity and efficiency of the proposed hybrid system. To decide which regions are suitable for the hybrid system, it will be necessary to analyze available wind and tide records from NIWA, and online databases such as GLOBAL ATLAS. This next phase of research will aim to create optimized scenarios for the hybrid model by considering the effect of wind and water speed on performance. After deciding which region and scenarios are suitable, it will also be necessary to evaluate the costs and returns of a hybrid system. This final phase will be performed using the RETScreen simulation model.

Abstract:

The economic feasibility of solar wall system was assessed with RETScreen software for 15 widespread locations in northern China heating region. Several different economic and financial indicators were calculated, such as the internal rate of return, net present value, simple payback and benefit-cost ratio. Results showed that the solar wall system was only profitable for four sites according to the current domestic price of solar wall plate and its absorptivity. When the price was reduced or the absorptivity under the condition of invariable price was improved, there were more sites profitable for this system. So, only when the price of energy increases 95% or the price of solar wall plate falls 50%, the solar wall system will be profitable for all sites in northern China heating region.

Abstract:

Simulation studies for a PV system would be useful for planning before real implementation, and to predict the cost for a large scale PV system. This work is to simulate a 3 kWp rooftop photovoltaic (PV) system under the climate of Surabaya, Indonesia. SolarGIS PV Planner and RETScreen simulation tools are used in this work. The simulation results are then compared with a full year of measurement results. The results of simulations show that a 3 kWp rooftop system could produce electricity of 4,200 kWh per year, while in the real measurement energy production is found about 3,898 kWh per year. There were slightly different results values of energy output between Simulation and real measurement of the PV system, however statistically it still can be accepted. Economic analysis shows that, under current conditions, a grid-connected PV system investment would give about 5 years of the payback period. Environmentally, the 3 kWp PV system would provide a reduction of CO2 emission of about 2.7 tons per year.

Abstract:

This article proposes a database of reliable wind velocities across the whole Ghana divided into 24 locations, based on data collected for the year 2013, although the bigger plan is to cover the period 2013–2018. For the year 2013 specifically, the proposed data were obtained through extrapolation of RETScreen data on wind velocity in Ghana, originally taken at a height of 10 m to a height of 60 m, adequate for generation using Weibull distribution function. The model led to the determination of the shape factor k and the scale factor c for all the 24 locations which subsequently led to the extrapolated wind velocity. The lowest and highest wind speeds were recorded, respectively, as 3.77 and 8.24 m/s for Wenchi and Wa locations in Ghana. The utmost relevance of this article is of national dimension to Ghana as the resulting wind velocities may be useful to undertake feasibility studies or real implementation of wind power plant.

Abstract:

Wind resource potential is strongly influenced by the exposure, orientation of the terrain and the wind direction. In Pakistan, the northern areas have very attractive sites for wind power plants. However, due to non-standardized masts installed, the collected data are not reliable. Due to the unreliable nature of available data, the investors normally avoid the investing in the wind power projects. Various software and tools have been used so far for the feasibility analysis but due to unreliable data, the proper feasibility analysis is still out of sight. To overcome this deficiency, a feasibility study of a wind power project in the Hunza Valley of Pakistan using reliable data is presented in this paper. For this purpose, the RETScreen is used by exploiting the standard NASA’s (National Aeronautics and Space Administration) database. Since the developing countries are facing problems in the development of wind projects, it is envisaged that this approach will give an easy way to launch new clean energy projects.

Abstract:

The continuous desire to drift from the conventional sources of energy to renewable energy resources is stymied by the intermittent nature of some of renewable sources such as solar and wind. However, analyses on some of the required conditions in which intermittent energy resources will be attractive and when it will be less attractive are presented in this paper.Pearson’s product moment of correlation coefficient (r) technique was used to calculate to calculate the correlation coefficient with respect to how three distinct hourly load profiles relate to the available solar radiation. The three calculated r values were analysed and applied as the operating strategies for modelling the power system in RETScreen softwareThe results from the three strategies employed show that the positive r value strategy was the most viable option and it can compete with the diesel only system.Therefore, for a distributed power generation system that utilizes an intermittent energy source, the relationship between the intermittent source and the load profile should be considered as an important indicator for determining the feasibility of the project.

Abstract:

Thermal efficiencies of Combined Heat and Power (CHP) and Tri-generation system, which are installed in a residential district and a general hospital, respectively, are investigated by using RETScreen. Economic feasibility and amount of CO 2 reduction are also estimated by comparing them with separate energy system, which separately supplies electricity, heating and cooling energy to consumer. When power generation capacity of the CHP system is changed from 26 to 40 MW, the efficiency is the highest at 26 MW. It is found that equity payback period is 5.7 years. Power generation capacity of the Tri-generation system for a general hospital was estimated to be 3.2 MW. Depending on the insulation amount of the building, profits and operating efficiency of the Tri-generation system are significantly changed. As an operating strategy, the type of following electricity load shows the highest thermal efficiency of 86%. When cost of electricity is raised by 10% and 20% of the present price, simple payback period is reduced from 5.2 years to 3.0 and 2.1 years, respectively.

Abstract:

The present study analyzed the potential of eight operational mining sites in Uzbekistan for the installation of photovoltaic (PV) systems: Sarmich, Ingichka, Kuytosh, Yakhton, Chauli, Sherobod, Chorkesar, and Tebinbuloq. A PV system with 1 MW capacity, which required a total of 4926 m2 of project land, was considered. The renewable energy analysis software RETScreen, developed by Natural Resources Canada (NRC), was used to calculate energy production, greenhouse gas reduction, and financial factors of the PV systems in the selected study areas. The iron mine Tebinbuloq in Karakalpak showed the highest potential, with annual electricity production of approximately 1685 MWh, equating to a potential reduction of approximately 930 tons of greenhouse gases. The economic benefit of the PV system in this mine was $2.217 million USD net present value with a project payback period of approximately 13 years. The results of precision checks of satellite- and ground-based solar measurements showed high correlations; hence, satellite-based data can be applied for solar project assessments where solar monitoring meteorological stations are not available.

Abstract:

Generating energy from renewable sources, particularly solar energy, offers significant benefits and achieves a more clean and sustainable development. In the present paper, the potential of developing a 4.2kW grid-connected rooftop two-axis tracking PV system in 25 selected coastal Mediterranean cities located in different Arabic countries is evaluated using RETScreen software. The proposed system is serving the basic household energy needs according to the load profile from monthly electrical bills. It is found that the proposed system produces about 8824kW annually, which helps to reduce CO2 emissions. Also, the average energy production cost is assumed to range from 0.0337 to 00.0475$/kWh. It is concluded that the proposed system can provide an effective solution for energy poverty in developing regions with a very positive socio-economic and environmental impact. The small-scale grid-connected PV system will provide the domestic energy needs at a lower energy production cost than the electricity price grid-connected consumers pay. This study demonstrated that generating electricity from solar energy will help reduce the electricity tariff rates and the dependence on fossil fuels.

Abstract:

The possibility of incorporating several subsystems using successive, in parallel or combined links, in a complex system with a well-defined goal, has given the possibility of proposing a new model for the integrated system - in series – in order to assure the heating and domestic hot water independence of a residential building, and in order to use the Retscreen International software, to simulate its functioning. An integrated system, can be conformed in several ways, each scheme having some technological, organizatorical variants, but with different economic effects. In choosing the optimal variant of a category of installations, there are used some techniques of analysis the economic performance. In the simulation of the functioning of the integrated system which assures the heating and the domestic hot water there have been proposed a series of work parameters, namely: the destination of the building, the climatically zone, the demand of hot water, the medium demand of thermal energy concordant to the climatically zones, the cost of natural gases, the price of the wooden fuel, the inflation rate, the service duration of the equipment, the cost of system’s maintenance, etc.

Abstract:

A demanda por fontes renováveis de energia tem aumentado nos últimos anos em função do crescimento econômico do país e pelo incremento de tecnologias no setor agropecuário brasileiro, contribuindo para a intensificação do uso de energia elétrica nas diversas atividades agrícolas. Um dos entraves que diminui significativamente a renda dos produtores familiares nos Perímetros Irrigados é o gasto com a energia elétrica utilizada para acionar os sistemas de irrigação, podendo chegar a 35% do custo total de produção. Diante desta problemática, objetivou-se com este trabalho realizar um estudo de viabilidade econômica e estimativa de produção do biogás como fonte alternativa para a geração de energia elétrica a ser utilizada no Perímetro Irrigado. Foi utilizado o software RETScreen® para análise de viabilidade econômica e estimativa de produção, e os principais indicadores de viabilidade econômica foram o payback e a taxa interna de retorno. O estudo demonstrou ser economicamente viável a utilização do biogás proveniente dos resíduos vegetais e animais, como fonte de biomassa para geração de energia elétrica. Portanto, quanto maior a quantidade de matérias vegetais e dejetos de animais disponíveis aumenta-se a geração de energia elétrica e, consequentemente, a viabilidade econômica do sistema de geração.

Abstract:

Transpired solar collector (TSC) systems are simple solutions for the preheating of ventilation air with solar energy. Their performance is a function of several environmental factors, so the climatic conditions of the location play an important role. In this paper, the effect of different climatic zones on the thermal performance of the TSC is investigated. To exclude other sources of influence, the same reference industrial building is examined in four Turkish locations (Antalya, Istanbul, Ankara and Sivas) representing different climatic conditions. RETScreen simulation is carried out for all four regions to obtain the drop of conventional heating requirement in case absorber azimuth of 0°, 45° and 90°. To illustrate the performance, temperature rise, heating energy savings and annual solar fraction are presented. Generally, it can be stated that a location with cold climate and high solar radiation at the same time benefits most from the use of a TSC system. A mathematical correlation has been found showing the solar fraction's dependence on solar radiation and heating degree days. Finally, simulation results have been compared to a set of measurement data from an industrial building's TSC system near Istanbul.

Abstract:

Pakistan suffers worst energy crises due to unavailability of primary energy sources. One of the solutions to energy problems of Pakistan lies in utilization of renewable energy sources like solar energy. One of the possible uses of solar energy is in the form of water eating. This work explored the availability of solar energy in the Sindh province of Pakistan. Moreover potential fuel savings and reduction in CO2 emission due to the use of solar water heating system is also evaluated. The RETScreen software was used for evaluation of fuel savings and CO2 emission reduction from a solar water heating system. Results show that the annual natural gas supplied to an average household in the three main cities of Sindh i.e., Karachi, Hyderabad and Sukkur could be reduced by 513.5, 409 and 543.5 m3, respectively. Annual reductions in emissions of CO2 for Karachi, Hyderabad and Sukkur were estimated to be 1, 0.8 and 1 tCO2 respectively. It is concluded that the utilization of solar energy for water heating in domestic sector of Sindh Pakistan could save fuel fossil and reduce environmental pollutants that in-turn may help mitigate energy crises in the country.

Abstract:

Due to environmental and economic drawbacks of fossil fuels, global renewable energy (RE) capacity has increased significantly over the last decade. Solar photovoltaic (PV) is one of the fastest-growing RE technologies. Selecting an appropriate site is one of the most critical steps in utility-scale solar PV planning. This paper aims at proposing a rational multi-criteria decision-making (MCDM) approach based on the Brown–Gibson model for optimal site selection for utility-scale solar PV projects. The proposed model considers the project’s net present value (NPV) along with seven suitability factors and six critical (constraint) factors. The RETScreen software was applied in calculating the NPV, the simple payback period and the carbon emission savings of the project at each alternative site. The weights of the suitability factors were determined using the analytical hierarchy process. Applied to the case study of finding the best location for a 5 MW solar PV project in northern Cameroon, the optimization results showed that Mokolo was the optimal location. The sensitivity analysis results revealed that the rankings of alternative sites based on the project’s NPV and the proposed model are not consistent. Compared to the traditional MCDM approaches, the proposed model provides decision-makers with a more practical thinking method in the optimal location process of utility-scale solar projects.

Abstract:

Libya is currently interested in utilizing renewable energy technologies to reduce the energy dependence on oil reserves and Greenhouse Gas (GHG) emissions. The objective of this study is to investigate the feasibility of a 10MW grid-connected PV power plant in Libya. NASA data are used to analyze the global horizontal irradiation, direct normal irradiation, and air temperature of 22 selected locations in Libya and to evaluate the potential of solar energy. RETScreen software is used to estimate the energy production, GHG emissions, and financial parameters for the 22 locations. Based on the solar atlas map, it is noticed that the highest global horizontal irradiation is in the southern part of Libya, which ranged from 2100 to 2500kWh/m2. These results indicate that Libya has a huge solar energy potential that can be used to ‎generate electricity. Moreover, based on techno-economic results, it is observed that the highest electricity generation of 22067.13MWh is recorded at Al Κufrah and the lowest at Al Jabal al Akhdar with a value of 17891.38MWh. Furthermore, Al Kufrah and Murzuq are the best locations for the future installation of PV power plants from annual energy and the economic parameters point of view. The maximum value of power that can be generated by the plant was estimated to be 22.06GW.
