German Chancellor Scholz pointed out that the major challenge facing the industry is high energy prices. The impact of rising energy prices on the steel industry, coupled with supply chain bottlenecks, has made the already severe situation worse. Scholz emphasized that the next goal of the federal government is clear, that is, to ensure that Germany has a climate-friendly electricity and energy industry, and at the same time, to make the corresponding prices affordable for people and businesses.
