In 2023, the UAE adapted its National Energy Strategy to accommodate several new goals, including doubling renewable energy (RE) capacity 14 GW by 2030. This development further highlights significance of transitioning towards RE sources. study focuses on examining and assessing utilization technologies in Sharjah, an emirate United Arab Emirates (UAE). It offers overview Sharjah’s current scenario investigates factors influencing adoption area. Furthermore, it provides evaluation installations, production capacity, future prospects for Sharjah. These findings contribute a deeper comprehension transition potential The analysis uncovers growing inclination adopting Solar installations are experiencing upswing, driven advancements technology, cost reductions, supportive policies. However, wind remain limited due lower region. Sharjah yields advantages, reduction greenhouse gas emissions, diversification sources, economic expansion. Nevertheless, challenges like intermittency, grid integration, initial investment costs require attention expedite adoption. outlook appears promising. Sustained government backing ongoing research efforts, addition collaborations between public private sectors, can facilitate wider implementation technologies. Implementing policies that encourage uptake RE, such as feed-in tariffs net metering, should be considered. Additionally, partnerships with international organizations exchange best practices enhance knowledge transfer building.

This study examines the complex interplay between food security, climate change, population, water, and renewable energy desalination in five Arab countries: Morocco, Egypt, Jordan, Saudi Arabia, United Emirates. Using a comprehensive econometric approach: an Auto-Regressive Distributed Lag approach (ARDL) Vector Error Correction Model (VECM) technique spanning 1990–2022, to explore short- long-run dynamics of these relationships identify causal linkages. The ARDL results reveal mixed outcome. While capacity holds potential for enhancing security all countries, its impact depends on cost government support. negatively affects most cases, highlighting need cost-effective solutions. Climate change poses significant threat, particularly but it may also offer unexpected opportunities KSA UAE. Population growth, unsurprisingly, strains across region. Water scarcity emerges as major challenge, especially Jordan. Granger causality tests uncover bidirectional desalination, water Morocco suggesting their interconnected influence. In imports drive system, while UAE exhibit with acting key drivers. Policymakers facing challenge countries should take note this research’s multifaceted findings. promise, success hinges reducing costs through technological advancements support, adaptation strategies must be prioritized, recognizing potentially regions like Additionally, addressing innovative resource management is crucial, Managing population growth family planning initiatives promoting sustainable agricultural practices are vital long-term security. Finally, identified underscore integrated policy approaches that acknowledge interconnectedness factors.

Renewable energy communities (RECs) aim at achieving economic, environmental, and social benefits for members society. This paper presents a roadmap the design, operation, monitoring of renewable in Italy, fundamental to guide orient any stakeholder involved decision-making process REC. The is inspired by Deming Cycle, also known as Plan-Do-Check-Act, which provides framework continuous improvement standardization procedures. To demonstrate practical application roadmap, real case study presented Italian communities, making full adoption data derived from official databases using urban district study. findings phase I “do” stage indicate that REC could lead decrease carbon emissions roughly 38% support 51 67 families through REC’s revenues, depending on installed PV capacity. Furthermore, both physical self-consumption virtual schemes assist sustainable transition built environment, where consumers have significant impact electrical markets. Therefore, these results validate roadmap’s effectiveness promoting an informed design implementation RECs while guiding energy, social, political decisions.
