In Puerto Rico, an oil tanker will begin unloading 300,000 barrels of diesel fuel to the island, after the Biden administration granted a limited exemption to shipping restrictions under the century-old Jones Act. In a statement, the Department of Homeland Security said the fuel was needed to provide electricity to critical facilities, as Puerto Rico recovers from Hurricane Fiona. Nearly two weeks after the storm collapsed the island’s fragile electrical grid, about 20% of homes and businesses remain without power, and there are widespread shortages of clean drinking water.
