“Polish refiner Orlen has in recent months chartered at least 10 tankers that previously shipped Russian oil to Asia to deliver Arab crude to its refineries in Lithuania and Poland on their return journey, according to two traders and LSEG data. Many oil majors have avoided contracting tankers that have carried Russian crude because of the risk of sanctions and self-imposed restrictions. Using the tankers operated by non-Russian shipping firms, but delivering Russian oil and products is not in breach of any sanctions, but the shipments are subject to the price cap policy imposed by the Group of Seven (G7) leading economies.”

“Traditional geothermal plants, which have existed for decades, work by tapping natural hot water reservoirs underground to power turbines that can generate electricity 24 hours a day. Few sites have the right conditions for this, however, so geothermal only produces 0.4 percent of America’s electricity currently. But hot, dry rocks lie below the surface everywhere on the planet. And by using advanced drilling techniques developed by the oil and gas industry, some experts think it’s possible to tap that larger store of heat and create geothermal energy almost anywhere. The potential is enormous: The Energy Department estimates there’s enough energy in those rocks to power the entire country five times over and has launched a major push to develop technologies to harvest that heat.”

“Afghanistan’s Taliban has signed seven mining contracts that would bring roughly $6.5 billion in investments to the ruling government, the Associated Press reported on Thursday. This figure, AP says, represents the biggest round of deals made by Taliban since seizing power two years ago. According to AP, the contracts are with locally based companies, many of whom have foreign partners in countries including China, Iran and Turkey. They include the extraction and processing of iron ore, lead, zinc, gold and copper in four provinces: Herat, Ghor, Logar and Takhar.”

“The theory that shifting thermal dynamics within the oceans may be intensifying this El Niño is not yet proved, but there is no question that global warming more broadly is set to make El Niños worse. “As climate change unfolds, the impacts for a given El Niño are not the same, they’re bigger,” says Adam Scaife of the Met Office, Britain’s meteorological agency. Global warming means the air is more charged with water, rainfall fluctuations are increasing, “and therefore, a given El Niño with the same strength as we had in the past can dump more water or cause a bigger drought.” Whereas the “triple dip” La Niña masked some warming, making temperatures cooler than they would otherwise have been, an El Niño will amplify it.”

“The European energy crisis is a wake-up call to the dangers of fossil fuel dependence. But too many countries are hitting the snooze button. Putin’s attempt at energy blackmail highlights more profoundly than ever before how continued reliance on fossil fuels not only harms the climate but also threatens security and prosperity. Although Europe avoided the immediate threat of winter shortages, thanks in part to mild temperatures, too few leaders are doing enough to reduce their susceptibility to such blackmail in the future. Instead of taking comfort in escaping Putin’s energy trap, governments must do more to speed away from fossil fuels and ensure that such vulnerabilities become a thing of the past.”
