We arrived at the Bavarian village of Iffeldorf the morning after the first snow, in late November, 2015. Dr. Uta Raeder, Co-Director of the Technical University of Munich (TUM) facility, greeted us in the parking lot. We huddled close, straining to catch her words before the wind, or traffic noises took, them away. She and her colleagues has been considering keeping us indoors. Instead they led us toward the boathouse, to see how they are monitoring how the climate is changing Germany’s lakes.
Germany added 2.3 GW of new onshore wind capacity in the first half of 2017. Though it failed to meet the target last year, the Renewable Energy Act set annual target of installing 2.5 GW new solar capacity.

But this project is only one of the reasons why we need to look at Hamburg Wasser.
