The U.S. stock market has taken its worst hit this week since March 2020, with the S&P 500 falling over 10% in just two days, while the tech-heavy Nasdaq is down 22% from its all-time high in December. The tremendous decline in stock values is a reflection of Donald Trump’s chaotic attempt at reordering the global economy, wrenching America’s average effective tariff rate to the highest level since 1909 — four years before the establishment of the federal income tax.

The clean energy economy has not been spared, although the effect has hardly been uniform. Some of the highest flying companies of 2024 and early this year — think Tesla or anyone selling power to a data center — have been some of the hardest hit, while some companies closer to the residential solar market have held their own.

President Donald Trump has exempted some — but certainly not all — of the critical minerals necessary for the energy transition from the sweeping tariffs he announced Wednesday. Minerals such as lithium, nickel, cobalt, manganese, and copper are key components of clean energy infrastructure such as lithium-ion batteries, which are used in electric vehicles or stationary storage, and copper wires, which conduct electricity in solar panels and wind turbines.

The White House has published a complete list of hundreds of products that are exempt from tariffs. We combed through the list looking for key transition minerals. Here are the ones that caught our eye, plus some that were notably left off. If you see anything on the list you think we missed, my inbox is open.
