For years, perovskites have been hailed as the "holy grail" of solar energy thanks to their promise of highly efficient and cheaper solar cells. Perovskites are a class of materials with similar crystalline structures with high superconductivity, high magnetoresistance, and high ferroelectricity, making them a potential replacement for silicon. Perovskite thin-film PV panels can absorb light from a wider variety of wave-lengths, allowing them to reach efficiencies of around 40% compared to silicon's theoretical limits around 30%. Unfortunately,…

Earlier this week, Brent crude slipped below $60 per barrel, and West Texas Intermediate dipped to $55, under the combined weight of a projected supply overhang and media reports claiming the United States and Russia were close to a peace deal for Ukraine. Even a blockade on sanctioned tankers carrying Venezuelan crude ordered by President Trump did not do much for prices. The question now is just how low Brent and WTI could sink from here. President Trump said this week that a peace deal for Ukraine is closer than ever. However, this may be just…

Mexico’s state oil giant Pemex is struggling to reverse a years-long decline in oil and gas production while trying not to incur additional liabilities on top of its already massive pile of $100 billion debt that makes it the world’s most indebted energy firm.   Petroleos Mexicanos, as Pemex is officially known, has received major government support this year under Mexico’s President Claudia Sheinbaum. Unlike her predecessor and mentor, Andrés Manuel López Obrador, incumbent President Sheinbaum has signaled…

The visit of Russian President Vladimir Putin to Indian Prime Minister Narendra Modi just over a week ago seems to have been overlooked by many geopolitical observers, which is surprising. It represents one of the most consequential recalibrations of India–Russia ties in years -- combining defence access, energy guarantees, and diplomatic symbolism -- at a moment when global alignments are shifting faster than ever. At the heart of the visit was the ratification of the ‘Reciprocal Exchange of Logistics Support’ (RELOS) pact, a…

For years, heat pumps were seen as the fragile heroes of mild climates, efficient in theory but unreliable when the mercury dropped. That narrative has now collapsed under the weight of experience. From the frozen lakes of Finland to the prairies of Canada, heat pumps are thriving where they were once thought impossible. The data from the multiple past winters tells the story clearly. Even in subzero temperatures, installations are growing faster than almost any other clean heating technology. This shift is more than a technical achievement; it…

U.S. gasoline prices are set to fall to the lowest level since 2020, thanks to increasing supplies, despite some ongoing refinery maintenance, GasBuddy has predicted. GasBuddy has predicted that U.S. motorists will pay an average of $2.79 per gallon on Christmas Day, down from $2.95 per gallon a year ago. That will mark the cheapest gas since prices averaged $2.26 per gallon in the Christmas of 2020. “Christmas is often when gas prices settle near the lowest levels of the year, and 2025 is no exception,” said Patrick De Haan, head of…

Brazil, Guyana, and Argentina are set to be major drivers of non-OPEC oil supply growth in 2026, accounting for half of the expected 0.8 million barrels per day (b/d) increase in 2026 the U.S. Energy Information Administration has predicted. According to the energy watchdog, Brazil's growth will mainly be driven by new offshore pre-salt projects coming online, including the start-up of Equinor’s (NYSE:EQNR) Bacalhau field in October as well as the start-up of two additional FPSOs by Petrobras in December. EIA has projected a 0.2 mb/d increase…

Since early December 2025, a wave of protests has swept across Iran, ranging from human rights campaigns in major urban areas to labor strikes in industrial hubs. As Statista's Tristan Gaudiat reports, part of the growing popular unrest concerns the accelerating use of the death penalty by the Iranian regime (more than 1,000 executions documented so far in 2025), while the country's economic situation has significantly deteriorated. Iran is currently facing one of its most severe economic and social crises of the decade, as the country grapples…
