Summary: The study used data from stations in the nine states of the Brazilian Northeast region to model historical wind speed series, revealing persistent multifractal behavior across all stations. The highest mean wind speeds were observed in Rio Grande do Norte, Paraiba, and Pernambuco, while the lowest were found in parts of Bahia, Piaui, and Maranhao. Multi-fractal analysis showed that the wind speed series exhibit persistent overall behavior dominated by small fluctuations.

Summary: The rollout of China Pakistan Economic Corridor (CPEC) has helped Pakistan achieve faster economic and financial stability. Pakistan, located in a significant geographical position in Asia, has immense renewable energy potential, primarily wind energy, in its Sindh, Balochistan, and Khyber Pakhtun-Khwa provinces. This study focuses on twelve selected sites in these provinces and uses the Weibull probability distribution technique to assess their wind power potential. The results show that Sindh is suitable for commercial-scale wind farm development, Balochistan is appropriate for utility-scale wind power development, while Khyber Pakhtunkhwa is unsuitable for commercial-scale due to low wind speeds throughout the year.

Summary: India's increasing electricity generation capacity must meet the demands of domestic consumption, energy security, and climate change accords. To achieve the goal of 40% non-fossil fuel electricity by 2030, a greater focus on renewables is necessary, particularly wind energy. This study uses reanalysis data to estimate India's wind power potential, finding that both onshore and offshore regions have significant potential, with up to 7.2 TW and 18.4 TW respectively. Sparsely vegetated areas have an additional 53 TW of wind power potential. Future efforts should concentrate on the availability of wind resources near energy-hungry regions.
