Abstract:
Conversion of solar energy to useful chemicals has become necessary for finding solutions to energy and environmental issues. One of the means is to use of solar energy for the reduction of water to generate hydrogen or for the reduction of CO[Formula: see text] to useful chemicals. In spite of substantial effort, the discovery of stable and efficient photocatalysts remains a challenge, although some encouraging results have been reported. In this article, we provide a brief perspective of the current status of solar water splitting and reduction of CO[Formula: see text].

Abstract:
The article presents the assessment of the environmental impact of 9 variants of building heat supply for heating purposes. The building energy standards and the main primary energy carriers being in use in Poland were taken as input data. The subject of analysis was a single-family house characterized by a utility energy demand of 47 kWh/(m2 year). An environmental impact analysis was made using the specification for LCA in damage categories encompassing human health, ecosystem quality and natural resources depletion. From the obtained results it has been found that coal-based technologies in Poland's building energy supply systems are capable of reducing the noxious environmental impact. An example of such a system is the effective heat distribution network with a coal-based cogeneration energy source. From the point of view of radical low emission reduction, an interesting solution is the effective heat distribution network with a gas-based cogeneration energy source. Nevertheless, forecasts about the development of renewable energy source installations in Poland indicate that a significant role in building heat supply systems will be played by solar systems and geothermal systems using heat pumps. Achieving the environmental acceptance of heat pumps in Poland's conditions requires a decisive intensification of efforts to increase the share of renewable energy sources in electric energy generation processes in the central electric power system and in local and individual systems, as well as the continuation of the processes of thermal insulation of already existing buildings.

Abstract:
The demand for clean energy is strong, and the shift from fossil-fuel-based energy to environmentally friendly sources is the next step to eradicating the world’s greenhouse gas (GHG) emissions. Solar energy technology has been touted as one of the most promising sources for low-carbon, non-fossil fuel energy production. However, the true potential of solar-based technologies is established by augmenting efficiency through satisfactory environmental performance in relation to other renewable energy systems. This paper presents an environmental life-cycle assessment (LCA) of a solar-photovoltaic (PV) system and a solar-thermal system. Single crystalline Si solar cells are considered for the solar PV system and an evacuated glass tube collector is considered for the solar thermal system in this analysis. A life-cycle inventory (LCI) is developed considering all inputs and outputs to assess and compare the environmental impacts of both systems for 16 impact indicators. LCA has been performed by the International Reference Life Cycle Data System (ILCD), Impact 2002+, Cumulative Energy Demand (CED), Eco-points 97, Eco-indicator 99 and Intergovernmental Panel on Climate Change (IPCC) methods, using SimaPro software. The outcomes reveal that a solar-thermal framework provides more than four times release to air ( 100 % ) than the solar-PV ( 23 . 26 % ), and the outputs by a solar-PV system to soil ( 27 . 48 % ) and solid waste ( 35 . 15 % ) are about one third that of solar-thermal. The findings also depict that the solar panels are responsible for the most impact in the considered systems. Moreover, uncertainty and sensitivity analysis has also been carried out for both frameworks, which reveal that Li-ion batteries and copper-indium-selenium (CIS)-solar collectors perform better than others for most of the considered impact categories. This study revealed that a superior environmental performance can be achieved by both systems through careful selection of the components, taking into account the toxicity aspects, and by minimizing the impacts related to the solar panel, battery and heat storage.

Abstract:
Considered a proposal to combat global warming, which consists in placing the creation of information in near-earth space. It is shown that instead of a space solar power plant that transmits energy to terrestrial consumers, it is more profitable to organize an orbital territorial-production complex, in which a new information and communications energy production cycle is implemented: the energy received from the Sun is used on site to create and store valuable information, and instead of an unused technology of wireless energy transmission to Earth, using a well-functioning space communication technology. Using the simplest mathematical model, it was demonstrated that the profitability of orbital information must be considered taking into account the anthropogenic impact on the climate of ground data centers. The dependence of the profitability of an information orbital product in comparison with a ground-based analogue on the cost of emission quotas for waste heat and greenhouse gases is discussed.

Cost analyses show that buildings with a higher cooling load and full load hours have lower costs. For high internal gains, cooling costs are around 1,7 €/kWh and 2,5 €/kWh for buildings with lower internal gains. Despite the fact that solar cooling systems have significant potential to reduce CO2 emissions due to a reduction of electricity consumption, the economic feasibility and attractiveness of solar cooling system is still low.

Abstract:
In recent years, with the continuous promotion of China’s marine power strategy, the comprehensive development and application of marine resources in many aspects and in depth has become a trend. China’s South China Sea is vast and rich in resources, which has important national defense, economic and environmental significance for its comprehensive development and construction. The South China Sea is a vast sea area with abundant wave energy and solar energy. The pilot development and application of natural energy in this area is of great strategic and environmental significance for the decentralized power supply of deep-sea islands. Therefore, based on the actual application of the wave energy-solar power generation platform on YX Island, a comprehensive analysis is carried out based on the characteristics of the marine climate and environmental elements of the South China Sea, exploring the apparent efficiency of intermittent energy such as wave energy and solar energy under specific environmental conditions and putting forward relevant suggestions. The forecast will provide relevant theoretical basis and data support for the subsequent in-depth development, application and system optimization of renewable energy in the South my country Sea.

Abstract:
A prior requirement to the design of any solar-based conversion systems is the knowledge of optimum orientation and tilt surface at which peak solar energy can be collected. In many parts of the world, however, the solar radiation data for the surfaces of interest are not always available. This paper presents a numerical approach to calculate the solar radiation on sloped planes by integrating the measured sky radiance distributions. The annual total solar yield at different sloped surfaces facing various orientations and monthly solar radiations at the optimal tilt surface and three vertical planes facing east, south, and west were determined. The energy outputs and efficiencies were simulated using a computer package. The environmental benefits in terms of greenhouse gases reductions and cost implications were also considered. The findings provide technical information for engineers to design and evaluate photovoltaic (PV) systems which could contribute to the environmental, energy, and economic aspects.

Abstract:
The growth of solar energy is projected to slow down during 2023–25 despite the fall in costs due to economic deceleration, reduced incentives, and market barriers including the lack of relevant and flexible energy project planning and decision-making tools. This study proposes a flexible and computationally simple multi-criteria decision analysis (MCDA)-based model that takes technical, financial, environmental, social and legal aspects of all project options as input and outputs a feasibility score for each option, which enables ranking the options and identifying the best alternative. The proposed model is applied to a real-world photovoltaic solar farm planned at a site in England and comprising nine different configurations formed by varying system capacity, energy storage option, mode of stakeholder, and network connections. The results of our study show that in this case the options without battery storage and a greater number of off-taker connections are more favorable than the options with battery storage. The analysis also shows that for the solar farm of the presented case study, ‘self-consumption fraction’ and ‘energy yield’, ‘net present value’, ‘life-cycle carbon emission reduction’, ‘ease of permit acquisition’ and ‘public approval’ are key sub-criteria for ‘technical’, ‘financial’, ‘environmental’, and ‘social and legal’ criteria, respectively. A sensitivity analysis was conducted to assess the confidence on the obtained solution, and a change in the first preference was noticed when ‘environmental’ and ‘social and legal’ aspects are given higher weight over ‘technical’ and ‘financial’ aspects. The results obtained are in line with the recommendations by experts, who carried out an independent feasibility analysis considering the same options.

Abstract:
As the demand of energy increases, renewable technologies are dominating in the recent years. Solar energy is one of the leading technologies in all of the renewable energies, due to its simplicity. In Pakistan, solar PV stand-alone units are mostly used to meet the energy requirements. During production of solar PV panel, it emits out lot of waste heat and it is necessary to calculate these emissions. This study investigates the complete Life Cycle Analysis (LCA) of two different types of solar panels which are locally available in Hyderabad markets. Complete modeling of Monocrystalline and Polycrystalline PV panels has been done by using GaBi software. This study shows the complete waste heat emissions during each stage of PV panel production. Two different types (Monocrystalline and Polycrystalline) of solar panels are designed under the dimensions of 1 m2. It is calculated that Monocrystalline PV panels are more efficient than Polycrystalline PV panels and they generates more units of electricity under same temperature conditions during its complete life. To enhance the electrical efficiency of solar PV panel, cooling system must be provided across it. The comparative analysis shows that Polycrystalline PV panels requires less amount of electrical energy as compare to Monocrystalline PV panels resulting in the reduction of waste heat emission. At the end of life, this study highlights the significance of recycling of solar panels which consider the reuse of the raw material. In this study, the combination of mechanical, thermal, and chemical process of recycling is considered. Recycling rate of solar PV panel has been assumed to be 90%. Recycling of raw material reduces the waste heat emission during purification process of raw material. Thus, cost is reduced and beneficial for environmental aspects. Result shows that recycling of solar PV panel is more beneficial than landfill for environmental and economic aspects.

Abstract:
The photovoltaic (PV) sector has undergone both major expansion and evolution over the last decades, and currently, the technologies already marketed or still in the laboratory/research phase are numerous and very different. Likewise, in order to assess the energy and environmental impacts of these devices, life cycle assessment (LCA) studies related to these systems are always increasing. The objective of this paper is to summarize and update the current literature of LCA applied to different types of grid-connected PV, as well as to critically analyze the results related to energy and environmental impacts generated during the life cycle of PV technologies, from 1st generation (traditional silicon based) up to the third generation (innovative non-silicon based). Most of the results regarded energy indices like energy payback time, cumulative energy demand, and primary energy demand, while environmental indices were variable based on different scopes and impact assessment methods. Moreover, the review work allowed to highlight and compare key parameters (PV type and system, geographical location, efficiency), methodological insights (functional unit, system boundaries, etc.), and energy/environmental hotspots of 39 LCA studies relating to different PV systems, in order to underline the importance of these aspects, and to provide information and a basis of comparison for future analyses.

Abstract:
Environmental Education is the key for creating a clean energy future for not only the nation, but the world. World Energy Consumption relies heavily on coal, oil, and natural gas. Fossil fuels are non-renewable, that is, they rely on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources, such as wind and solar energy, are constantly replenished and will never run out. Due to the rising need for professionals and academics with a background and understanding in the Energy field, Holon Institute of Technology (HIT) developed an integral system of environmental education and training and a new program at the Faculty of Electrical Engineering. The Renewable Energy program gives the students technical and practical aspects of energy use (technology and methodology of the study) and energy efficiency. The program also deals with minimizing the environmental impacts of energy use, as well as with energy economy and environmental policy. This article presents a new challenge.

This paper focuses the novel GIS-related aspects of a prototype planning support system for urban planners and energy advisers. The system design combines commercial database and GIS packages to provide a flexible means of predicting the solar energy potential and energy consumption of dwellings. By incorporating customised tools designed to derive useful data directly from digital maps and aerial photographs, it addresses the significant problem of data collection for urban-scale energy modelling. In conjunction with data generated by a new dynamic default data system, the map-derived data provide the necessary input for an embedded domestic energy model and a solar energy calculation engine. In this way, robust estimates can be obtained, at almost arbitrary scales of resolution, of the potential for solar energy to replace delivered domestic energy and to mitigate emissions of carbon dioxide.

Abstract:
Abstract. Increasing the production of clean and environmentally friendly energy has become one of the world agendas as a strategic effort in dealing with long-term climate change. Seeing the potential of the energy produced, the ease in the installation process, with the small risk of harm generated, solar energy has received significant attention from many countries in the world. The potential for solar energy in Indonesia alone reaches 207 GWp, but only 145.81 MWp has been utilized. Currently, the Indonesian government has set a target to build a Solar Power Plant capacity in 2025 of 6.5 GWh. Urban areas are areas with higher energy demand than rural areas, but the availability of vacant land in urban areas is very minimal for installing solar power plants. Therefore, rooftop solar PV(Photovoltaic) can be a solution in dense areas such as cities. Good planning by looking at the potential resources and energy needs in spatial is needed to manage and utilize energy optimally and sustainably in urban areas. This study aims to develop a geospatial assessment for plan smart energy city that uses rooftop solar PV's potential energy in every building that is effective and efficient. The novelty in the analysis of the distribution of the potential for rooftop solar PV development in urban areas integrates meteorological and spatial aspects and socio-economic aspects. Integration of multi-dynamic spatial data uses in determining the rooftop solar PV construction location, such as meteorological data for solar energy potential, increasing energy needs of each building, and socio-economy data. The data source used comes from statistical data and remote sensing data.

Abstract:
Renewable technologies could be utilized to solve the energy crises of world’s sixth most populous country, Pakistan. Being rich in renewable resources of energy, the demand of electricity in household sector of Pakistan can easily be fulfilled which is otherwise scarce and have made the life of common people highly miserable. To formulate proper policies concerning the development of alternate energy sector it is essential to evaluate and prioritize the renewable technologies. In the present paper the aforementioned issue of evaluation and prioritization of renewable technologies has been addressed using AHP (Analytical Hierarchy Process) with the aim that the financial, technical, societal and environmental aspects are not compromised. Six alternatives (namely solar, wind, biomass, geothermal, ocean and hydel energies) have been prioritized. It has been concluded that to get around the crises of domestic electricity shortfall the choice of solar energy technology is the best among the alternatives highlighted above, followed by wind and biomass. With reference priority of the choice of alternate energy it is also emphasized that the financial aspect must be the decisive factor.

Abstract:
Glazing is considered as a preferred solution for the buildability, aesthetic, and comfort of commercial buildings since glass cover can protect occupants from external environmental conditions, ensure the light transmission, and provide view and ventilation. At the same time, in the context of climate change and global warming, the use of renewable solar energy, such as solar and wind power, are encouraged to be utilized. Specifically, solar energy has become a renewable energy source that is clean and endless, at reasonable cost, to contribute to energy security as well as ensure sustainable development. Therefore, the study proposes a method for supporting the decision making in installing solar panels on vertical glazing façades of the building in the worst case that the remaining radiant energy from the sun was only transferred to the inside of the building. The Life Cycle Assessment and the Life Cycle Costing methodologies are applied to consider both environmental and economic aspects. The proposed method can (1) minimize the project cost (including initial investment cost and operation cost) during the building lifetime; (2) analyze the optimal budget to minimize the total life-cycle cost of the building over its lifespan and maximize the renewable energy generated from the sunlight entering buildings in different directions. The results show that with different initial investments, the investor will have a corresponding solution for choosing an optimal installation ratio for each type of glass combined with the installation ratio of solar panels on the façades to reach the optimal energy efficiency as well as environmental performance. This study is beneficial for investors in selecting energy-saving solutions in office buildings in the beginning phase of the project life cycle.

Abstract:
In this review, the concept of a hybrid solar cell system, called all-weather solar cells, a new view on energy harvesting device design, is introduced and described in detail. Additionally, some critical economical, technological, and ecological aspects are discussed. Due to drastic global climate changes, traditional energy harvesting devices relying only on solar energy are becoming less adaptive, hence the need for redesigning photovoltaic systems. In this work, alternative energy harvesting technologies, such as piezoelectric and triboelectric devices, and photoelectron storage, that can be used widely as supporting systems to traditional photovoltaic systems are analysed in detail, based on the available literature. Finally, some examples of all-weather solar cells composed of dye-sensitized solar cells (DSSC) and silicon solar cells, often modified with graphene oxide or phosphors materials, as new perspective trends in nanotechnology are presented. Two types of solar cell triggers are analysed: (i) solar cells working during day and night (DSSC with phosphors materials), and (ii) solar cells working under sun and rain conditions (piezoelectric and triboelectric silicon or DSSC solar cells).

Abstract:
Organic–inorganic hybrid perovskite solar cells (PSCs) have made immense progress in recent years, owing to outstanding optoelectronic properties of perovskite materials, such as high extinction coefficient, carrier mobility, and low exciton binding energy. Since the first appearance in 2009, the efficiency of PSCs has reached 23.3%. This has made them the most promising rival to silicon-based solar cells. However, there are still several issues to resolve to promote PSCs’ outdoor applications. In this review, three crucial aspects of PSCs, including high efficiency, environmental stability, and low-cost of PSCs, are described in detail. Recent in-depth studies on different aspects are also discussed for better understanding of these issues and possible solutions.

Abstract:
Climate change has become a major constraint to the development of rain-fed agriculture due to the decline of rainfall. Therefore, irrigated agriculture is an alternative allowing farmers to have more access to water in order to meet crop water requirements. However, irrigated agriculture faces a major constraint related to the accessibility of energy sources used in pumping water. In general, the most common energy sources used in pumping water for irrigation are fuel and electricity. Nevertheless, they are very expensive, are not always accessible particularly in rural areas in Africa and have a negative impact on the environment; hence the need to find alternatives to solve this problem. This review focuses on the technical and economic feasibility of solar irrigation pumps and the impact of their use on the environment. Several aspects related to solar pumping have been discussed, namely the components of the solar pumping system, the energy source used, the principle of operation of the system, the technical, economic, and environmental feasibility. Reviews show that the use of solar irrigation pumps is a technically and economically feasible alternative in several areas with less environmental impact.

Abstract:
Environmental contextStudies involving modelling are increasingly being performed to better understand how technology-critical elements such as tellurium are transported and accumulated in man-made technological systems. The resulting ‘anthropogenic cycles’ provide estimates of current and anticipated future material releases to the environment, and their associated environmental implications. This information complements data on natural cycles in which the subsequent transport and fate of tellurium in the environment can be examined. AbstractGlobal demand for tellurium has greatly increased owing to its use in solar photovoltaics. Elevated levels of tellurium in the environment are now observed. Quantifying the losses from human usage into the environment requires a life-cycle wide examination of the anthropogenic tellurium cycle (in analogy to natural element cycles). Reviewing the current literature shows that tellurium losses to the environment might occur predominantly as mine tailings, in gas and dust and slag during processing, manufacturing losses, and in-use dissipation (situation in around 2010). Large amounts of cadmium telluride will become available by 2040 as photovoltaic modules currently in-use reach their end-of-life. This requires proper end-of-life management approaches to avoid dissipation to the environment. Because tellurium occurs together with other toxic metals, e.g. in the anode slime collected during copper production, examining the life-cycle wide environmental implication of tellurium production requires consideration of the various substances present in the feedstock as well as the energy and material requirements during production. Understanding the flows and stock dynamics of tellurium in the anthroposphere can inform environmental chemistry about current and future tellurium releases to the environment, and help to manage the element more wisely.

Abstract:
AbstractAlkaline water electrolysis powered by renewable energy sources is one of the most promising strategies for environmentally friendly hydrogen production. However, wind and solar energy sources are highly dependent on weather conditions. As a result, power fluctuations affect the electrolyzer and cause several negative effects. Considering these limiting effects which reduce the water electrolysis efficiency, a novel operation strategy is proposed in this study. It is based on pumping the electrolyte according to the current density supplied by a solar PV module, in order to achieve the suitable fluid dynamics conditions in an electrolysis cell. To this aim, a mathematical model including the influence of electrode-membrane distance, temperature and electrolyte flow rate has been developed and used as optimization tool. The obtained results confirm the convenience of the selected strategy, especially when the electrolyzer is powered by renewable energies.

Abstract:
In the modern era, energy demand rises dramatically accompanied by the rapid growth of our population, causing urgent energy shortages and environmental issues around the globe. People turned their attention to solar energy for an eco-friendly and economic solution, in which, perovskite solar cells emerged and had caught a great deal of attention in the past decades for their promising and commercial development potential. To fully release their capability for a high-performance device, defect mechanisms which are one of the main factors inhibiting the efficiency and stability, as well as passivation strategies must be thoroughly studied. In this review, the concept and formation mechanism of the defects are summarized, the corresponding defect characterization techniques regarding their working principles and downsides were also compared. Furthermore, substantial passivation strategies were discussed. Although perovskite solar cells still have a long way to go, facing difficulties in a lot of other aspects, we believe that the research we are doing now is of great significance in making perovskite into a real application.

Abstract:
During the last decades, life cycle assessment (LCA) has been one of the most common approaches for environmental impact assessment. This methodology has become more and more complex in its representation of the real environmental impacts of products. However, it does not take into account temporal and cumulative aspects, and therefore appear not so suitable to observe potential rebound effect of new technologies. In this paper, we explore the limits of static LCA and understand how some dynamic LCA can be interpreted, by comparing the results of two environmental impacts assessments of energy production from solar cells. The global warming potential (GWP) of different technologies was accounted from the last 50 years. We show with this example how any temporal evolution of technology matters for environmental assessment (e.g. the global warming potential). Turning then to the future, we offer scenarios to see the evolution of greenhouse effect in long term regarding different mixes of technologies. This example opens new horizons for future research in the field of temporal LCA and its applications.

Abstract:
Renewable energy sector of India has the potential to be a credible alternative for households and communities. The sector accounts for approximately 13 per cent of the national energy capacity, including technologies such as solar grid/ off – grid generation, wind power, small hydro power, biomass/ biogas, and waste to energy. Statistics related to implementation illustrate the scope of tapping the renewable energy sector comprehensively, esp. for decentralized, household and community level applications. This paper analyses on – ground case studies and projects from various renewable energy categories, specifically the socio – technical and community aspects that play a significant role in successful Renewable Energy Technologies (henceforth RET) implementation. The distilled positive and negative drivers include technical, economic considerations, policy and regulatory, environmental aspects, market/ business models, and social/ community linked aspects. Case studies describe the need for a system based and stakeholder engagement approach where all possible stakeholders and their issues are envisaged and taken into account. Use of an evaluating framework is suggested to ensure successful community models of RETs and mass adoption of renewable technologies.

Abstract:
The growing energy needs of agriculture, the need to reduce the burning of fossil fuels, and, on the other hand, the increasing technical efficiency are contributing to the wider use of solar energy technology in agriculture. The aim of the article is to identify factors determining farmers’ investments in solar photovoltaic and solar thermal installations for electricity and heat production, to establish the proportion between the consumption of such energy for the needs of the farmer’s family and for the needs of the farm, and to identify the drivers of solar energy use in agricultural production. Empirical materials were collected through surveys of farmers conducted at the end of 2020 in south-eastern Poland, in the Podkarpackie region. It is a region characterized by significant land fragmentation. Producing energy from renewable sources can be an opportunity for farmers not only to reduce household expenses, but also to increase agricultural income. As a result, it can be a driver of sustainable agricultural development in the region. The article presents the most important economic and social determinants that stimulate the adoption of solar photovoltaic and solar thermal technologies by farmers for the needs of their households as well as for agricultural production.

Abstract:
Photovoltaics is amongst the most important technologies for renewable energy sources, and plays a key role in the development of a society with a smaller environmental footprint. Key parameters for solar cells are their energy conversion efficiency, their operating lifetime, and the cost of the energy obtained from a photovoltaic system compared to other sources. The optimization of these aspects involves the exploitation of new materials and development of novel solar cell concepts and designs. Both theoretical modeling and characterization of such devices require a comprehensive view including all scales from the atomic to the macroscopic and industrial scale. The different length scales of the electronic and optical degrees of freedoms specifically lead to an intrinsic need for multiscale simulation, which is accentuated in many advanced photovoltaics concepts including nanostructured regions. Therefore, multiscale modeling has found particular interest in the photovoltaics community, as a tool to advance the field beyond its current limits. In this article, we review the field of multiscale techniques applied to photovoltaics, and we discuss opportunities and remaining challenges.

This paper presents a high-level overview of the integration of renewable energy sources (RES), primarily wind and solar, into the electric power system (EPS) in Croatia. It presents transmission system integration aspects for the particular case of this country. It explains the current situation and technical characteristics of the current conventional generation units and currently installed wind energy capacities. Based on the current situation future development scenario is determined and used to evaluate the impacts of the wide-scale integration of renewables. Grid connections aspects, power balancing, market participation, and inertia reduction aspects are considered. Furthermore, some specifics of both solar and wind integration are discussed identifying problems and potential solutions. Primarily through the provision of the inertial response of both solar and wind and through better forecasting of wind production. Finally, the outlook for the Croatian power system is given, that will most probably double its RES capacity in the coming 3-year period and a certain level of investments and changes of current operational practices will need to be provided.

Abstract:
In the global effort to curb energy consumption and promote a sustainable lifestyle for our societies, we must strive to lower our energy needs in all aspects of our lives. One of the biggest contributors to our energy requirements are the buildings we spend most of our time inside. Buildings’ energy consumption can take many forms, such as, air conditioning, heating, ventilation, and lighting systems in order to create a comfortable environment for the users. One way of reducing buildings’ energy consumption is the use of renewable resource for energy. The main aim of this research is to measure and assess the public perceptions, knowledge and awareness of the concept of renewable energy, with specific regards to the use of solar photovoltaic cells, as well as investigate the desire to spend on the installation of renewable energy sources. Data was collected through a survey questionnaire applied in Irbid governorate in the north of Jordan. The statistical SPSS program was used to analyze closed-ended questionnaires and obtain numerical results based on arithmetical averages and percentages. The results show people are adequately aware of the benefits of renewable energy and most would like to have photovoltaic cells installed. However, 54.35% of the study sample live in apartments and do not have the space for the installation. 70.1% are open to the idea of sharing the solar energy system with their neighbors. 50% thought that the photovoltaic cells affected the aesthetics of the architecture style of the buildings especially the more traditional styles. It is concluded that the government needs to build a large-scale solar energy project to sustainably produce electricity instead of relying on individuals who generally lack the ability or the space for such systems, taking in note that the general public supports such concepts.
