As a country situated in region with abundant solar resources, Albania has enormous potential for using energy through photovoltaic (PV) systems. With the crisis repeating itself over years, now more than ever is moment to assess and fully use this opportunity. This paper studies current state of PV usage Albania's sector opportunities challenges coming together technology. Economic, social, environmental benefits are discussed, as well existing policies renewable energy. It evaluates technology's role country's sustainable transition analyzes various integration models like net-metering feed-in tariffs. Successful projects case highlighted, while such regulatory complexities public awareness discussed. The study also assesses large-scale feasibility emphasizes need integrated planning. research aims offer relevant information Albanian policymakers, stakeholders, investors support effective implementation systems cleaner, future. Furthermore, there lack about renewables reality. Enhancing sustainability reducing greenhouse gas emissions important.

Applying graph theory to find key leverage points in the transition toward urban renewable energy systems

Applied Energy, Год журнала: 2024, Номер 361, С. 122854 - 122854

Опубликована: Фев. 22, 2024

This article employs graph theory to quantitatively analyze the causal loop diagrams, focusing on transition decentralized renewable energy markets and identifying key variables acting as initiators reinforcers of this transition. The study utilizes a combination qualitative diagramming (CLD), SWOT analysis, theory, offering robust methodology applicable not only planning but across diverse domains. Key findings highlight significance profit-driven investment-based approaches, in tandem with political will strategic planning, integrating systems. Some variables, consistently present top ten graph-based measures, serve critical leverage points, including "Need for solutions" (in 6 out 10 measures), "Profit" (5 10), "Technological progress" "Consumers interest "Climate change" 10). Moreover, willingness customers engage market urban planning's role consumption patterns was found pivotal. presented approach offers valuable insights encourages holistic reevaluation systems, providing stakeholders comprehensive tool inform decision-making practices. research underscores importance well-established factors unveils specific nuances energy.

Optimal techno-economic design of PV-wind hydrogen refueling stations (HRFS) for 20 selected Saudi sites

Wind Engineering, Год журнала: 2024, Номер 48(6), С. 1055 - 1075

Опубликована: Апрель 29, 2024

The current study proposes a model of an autonomous HRFS installed on different sites in 20 Saudi cities powered by renewable clean energy sources. station is fully photovoltaic (PV) panels and wind turbines involving electrolyzer hydrogen tank for producing storing hydrogen. Three scenarios are investigated to propose optimized model, namely Scenario 1 containing (PV-Wind-Battery) system, 2 with (Wind-Battery) technologies, 3 (PV-Battery) components. expected feed the load demand 25 cars storage capacity 5 kg. simulation carried out using well-known HOMER software description technical parameters plant together detailed economic feasibility also performed. Furthermore, optimization process executed demonstrates competitive levelized cost (LCOE) (LCOH) especially third scenario LCOH varying within $12–15.9/kg LCOE range $ 0.332–0.414/kWh, all cities. For instance, encouraging lowest values net present (NPC) obtained futuristic NEOM mega city relatively first (NPC = $1,576,000, 0.627/kWh) $830,494, 0.332/kWh), respectively. On another hand, thorough analysis PV/Wind technoeconomic operation provided including improvements recommendations, comparison environmental impact discussion.

Critical skills needs and challenges for STEM/STEAM graduates increased employability and entrepreneurship in the solar energy sector

Renewable and Sustainable Energy Reviews, Год журнала: 2023, Номер 187, С. 113776 - 113776

Опубликована: Сен. 29, 2023

Energy produced by photovoltaic module (PVM) is poised to deliver the UN Sustainable Development Goal 7 (SDG-7) 2030 and Net-Zero 2050 but not until ample graduates with adequate Solar Technology (SET) skills are Higher education institutions (HEIs). Although PVM has witnessed significant penetration globally, sustainability of growth sector challenged attendant monotonic skilled labour shortages. The evolving imbalance critical in European Union (EU), limits her global competitiveness necessitates need create wider awareness on green technology stimulate more production solar energy (SES) specific graduates. Discussing mismatch between Europe needs SES, study outlines key Science, Technology, Engineering Mathematics (STEM) cum Arts (STEAM) ought possess secure employment challenges limiting them from acquiring competencies. review conducted via extensive relevant literature, analysis interviews observations. Academic, industrial, entrepreneurial identified as SES needs. Designing running educational modules/curricula that embed specialist students learners proposed vehicle increase their employability entrepreneurship. This profiles trends developments for stakeholders' increased while presenting in-demand sector. adoption SET Training (SETechTra) curricula/modules EIs will substantially industry-ready whilst decreasing gap.
