Where energy resources are concerned, lignite, hard coal and uranium figure principally in car production. For example, the iron demand is less because the share of steel is less, while the bauxite demand increases because of the higher light alloy share. The new C-Class shows a slightly higher level in this respect than its predecessor.
Thereby, we completely forego coal-based electricity and obtain our electrical energy from only renewable sources. Today, new plants in Europe are already planned with a CO2-neutral energy supply from the start. However, today’s production grids are powered by alternating current—which has to be converted.
