Trump Administration Launches National Security Investigation into Wind Turbine Imports

The Trump administration has initiated a national security investigation into imports of wind turbines and their components, citing concerns about foreign supply chains, government subsidies, and potential predatory trade practices. This move could further constrain the US renewable energy industry, leading to additional tariffs and a setback for the sector. The investigation, launched under Section 232 of the Trade Expansion Act, follows the administration's recent decision to raise tariffs on steel and aluminium imports for hundreds of products, including wind turbines.
