“…This work simulates the impact of hurricane shading in 2050 on PV solar generation sized to cover 50% of the total existing power capacity (including fossil power) in case of small islands or territories without publicly available official government targets for PV expansion. The basis for estimation of the projected utility-scale PV solar power capacity of the U.S. and Brazil in 2050, being 98.7% of the PV capacity interconnected by the U.S.-Caribbean-South America SG, was obtained from studies and plans elaborated on by the U.S. National Laboratories for the DOE and the Brazilian Energy Research Company [31,35]. The projected 2050 PV capacity of the U.S. and Brazil is detailed separately in Appendix B.…”

“…In Brazil, the Brazilian Energy Research Company, a Brazilian federal-owned organization, issued the National Energy Plan 2050 (PNE). The centralized PV generation capacity (excluding residential or commercial PV) is estimated to reach between 27 and 90 GW in 2050 [35]. In 2022, the centralized PV generation capacity in Brazil was around 18.…”

Solar photovoltaic (PV) generation technology stands out as a scalable and cost-effective solution to enable the transition toward decarbonization. However, PV solar output, beyond the daily solar irradiance variability and unavailability during nights, is very sensitive to weather events like hurricanes. Hurricanes nucleate massive amounts of clouds around their centers, shading hundreds of kilometers in their path, reducing PV power output. This research proposes a spatiotemporal method, implemented in MATLAB R2023b coding, to estimate the shading effect of hurricanes over a wide distribution of PV solar plants connected to a high-voltage power infrastructure called the U.S.–Caribbean–South America super grid. The complete interconnection of the U.S., the Caribbean, and South America results in the lowest power valley levels, i.e., an overall percentual reduction in PV power output caused by hurricane shading. The simulations assess the impact of hurricanes in 10 synthetic trajectories spanning from Texas to Florida. The Caribbean would also experience lower power valleys with expanded interconnectivity schemes. The U.S.–Caribbean–South America super grid reduces Caribbean variability from 37.8% to 8.9% in the case study. The proposed spatiotemporal method for PV power profile estimation is a valuable tool for future solar power generation expansion, transmission planning, and system design considering the impact of hurricanes.

“…However, some scepticism regarding renewable energy exists, especially in the context of solar PV waste, due to some toxic or rare metals and chemicals that PV systems contain. De Sousa et al (2023) state that end-of-life PV systems are not hazardous if treated right, and the value of generated solar power surpasses the possible environmental damage of properly disposed PV systems, which is minimised. Of course, in order to ensure proper utilisation of solar panels, technological solutions and processes should be developed, as well as political mechanisms and structures should be implemented.…”

Research background: In order to tackle climate change and ensure Paris agreements are met, countries are forced to look for alternative ways of producing, consuming, and wasting and adopt a circular economy. Reduction of greenhouse gas emissions becomes one of the key elements. The demand for electricity is increasing, and most greenhouse gas emissions derive from the energy sector. Because of that, it is crucial to ensure the transition from fossil fuels to renewable energy. Renewable energy, as a part of the circular economy, also contributes to sustainable development. Only the efficient implementation of circular economy and renewable energy practices can ensure that sustainable development goals are achieved. Purpose of the article: The study aims at determining the efficiency of European Union countries implementing circular economy practices through renewable energy to attain SDGs. The study focuses on the significance of renewable energy as a tool for the circular economy to achieve sustainable development and highlights the progress achieved in SDG through renewable energy in the EU. Methods: For efficiency assessment of the circular economy represented by the renewable energy indicators, data envelopment analysis (DEA) was performed. Findings & value added: This study presents a relation analysis of the circular economy and renewable energy and the importance of efficiency in achieving SDGs through a circular economy. The study helps to understand the circular economy represented by renewable energy and how it transforms into sustainable development and contributes to necessary actions needed for countries to improve. Based on the results, Sweden, Luxembourg, Ireland, Latvia, Estonia, Malta, the Netherlands and Bulgaria are considered the most efficient countries, while Austria is the least efficient. Unused solar and wind power potential can slow down sustainable development; however, EU programs and renewable energy strategies help countries move towards clean energy and ensure efficient implementation of sustainable development goals.

“…The lack of e-waste management from C&D wastes can lead to air emissions, dust, ground contamination, or fire risk. To avoid contamination and ensure the safe handling and management of e-waste from the construction industries, it is essential to understand the risks of impact on the environment from the e-waste [4]. E-waste collection and separation, handling, storage, and transportation stages should be customised based on their risks or hazards and on the key supply chain indicators to improve resource recovery efficiency.…”

E-waste or electronic waste uses electrical power from a power cord/plug/battery. Construction and demolition (C&D) industries use various electronic components such as cables, switches, sockets, electrical heat pumps, air conditioning systems, and solar panels, which become e-waste at the end-of-life-cycle stages. E-waste contains valuable metals/non-metals/plastics that are recoverable and recyclable. E-waste disposal is banned from landfills in Victoria (Australia), because of their toxic components that require an additional waste separation process to avoid considerable environmental emissions and costs of separation and safe disposal. This paper aims to review the alternative circularity scenarios for recoverable materials from e-waste the C&D industries. Alternative scenarios for e-waste handling and management originating from the C&D industries are assessed in the current study. We identify and assess the important circularity indicators and waste management steps that would drive towards the identification of future initiatives or policy development to increase the resource recovery from e-waste. The policies would help to advocate for policy development for the C&D industries’ e-wastes.
