Students:Day Three - sustainable campus and renewable energy

Began the day at 9am at Leuphana University with a presentation by Dr. Alexa Lutzenberger on renewable energies, which began with a description of the bottom-up movement in Germany to create renewables sources of energy following the Chernobyl nuclear reactor meltdown 30 years ago. Over those years it's been found that production of electricity from renewables is relatively easy in comparison to production of heating from renewables. Something like 65% of the housing stock in Germany is 80-100 years old or older and so is very inefficient in terms of heating insulation. One percent of the housing stock is being refitted each year with the goal of refitting all buildings by 2060.
