Researchers have developed a low-cost tool to assess rooftop photovoltaic (PV) potential in two informal settlements in Brazil, enabling the installation of approximately 577 solar modules, which could meet 61% of the average monthly electricity demand for each household. This methodology utilizes UAV photogrammetry and GIS analysis, comparing simplified irradiance models with detailed simulations from the University of Jaén and the Federal University of Bahia.

The 2026 Ipsos Energy Transition Barometer indicates a significant global shift towards solar energy, driven by rising costs and a desire for energy independence. The Global Solar Council is actively promoting residential rooftop solar in urban areas to enhance energy resilience. Concurrently, Australia is implementing its Future Made in Australia policy, specifically targeting emissions reduction in the iron and steel sector through investments in green technologies.

In Delhi, a new policy aims to eliminate gas-powered vehicles by 2027, promoting electric vehicles (EVs) to combat severe air pollution. This initiative includes subsidies for EV buyers and incentives for scrapping gas vehicles, though challenges remain in developing sufficient charging infrastructure and upgrading the electricity grid. As of the 2026 financial year, electric vehicles constituted 12.7% of new vehicle sales in the city, reflecting growing adoption amid these efforts.
