discovered 02.12 FOCUS WWW.Hzdr.DE In 2011 the German Federal Government announced an energy turnaround for sustainability, meaning that in the future Germany will not source its energy from nuclear power but will instead rely mainly on renewable energy sources. Energy efficiency is also being talked about more than ever. Private households have quite a lot of untapped potential to become more energy efficient by modernizing old homes with the latest thermal insulation or upgrading heating systems with state-of-the-art technology. On a much larger scale however, industry can contribute to energy efficiency by developing and using new technologies that are resource- and energy-efficient. As part of its new focus on energy, the Helmholtz-Zentrum Dresden-Rossendorf is looking at resource-intensive and energy-intensive production processes, like for example steel and aluminium casting or crystal growth. Similarly, in the production of raw chemical materials (the chemical industry // The casting process is a fundamental technology that uses a considerable amount of energy. As a result steel production is one of the most energy-intensive industrial processes around. The new Institute of Fluid Dynamics at HZDR hopes that its research will be able to redress this energy balance. _TEXT .
