The U.S. is on the verge of a lithium rush, crucial for renewable energy and electric vehicle batteries. In 2023, scientists found a massive lithium deposit in an ancient supervolcano, and in 2024, another significant reservoir was discovered in Pennsylvania’s fracking wastewater. Currently, the U.S. has only one large-scale lithium mine and relies on imports. The Department of Energy aims for domestic lithium production by 2030. However, expanding lithium mining is controversial due to environmental and Indigenous land concerns. Pennsylvania’s Marcellus Shale, rich in lithium, offers a potential solution.
