Germany is world-renowned for its ability to develop and produce innovative energy efficient technologies. On May 1, 2012, USEA will host several such innovators from the cites of Bottrop and Lingen, Germany for a discussion on implementing efficient technologies for the benefit of municipalities. Winner of the InnovationCity Ruhr project, Bottrop has developed a credible plan to reduce its CO2 emissions by 50% by 2020 while maintaining the city’s quality of life and enhancing its economic competitiveness. Technologies tested in Lingen include biogas-powered sewage treatment systems, hydrothermal carbonization and hydrogen from biogas.
