Our Challenge: Growing Demand - less CO 2 Renewable Energy Source: Shell AG - ‘Global Renewables Market’ 1999 2060: 60% renewables provide world GDP-growth Energy Need CO 2 -Reduction

Vattenfall Utilities in Berlin Quelle:Vattenfall Europe

Vattenfall District Heating in Berlin Quelle:Vattenfall Europe

Coal Use in the planned Coal Plant Waste Heat ca. 40%! District heating ca. 12%! Electricity ca. 48%!

Only 12% of the Coal goes to Heat

Only 4-8% CO2-Emissions needed!

The RenewableDistributed Power Plant ,[object Object],The combination and organized play together of wind, solar biomass and waterpower can follow the path of electricity demand over the day and year and can fully substitute conventional energy system

Solar Electricity Feed-in-Tarriff 2000-2011 Source: VDN beim VDEW In 2011 at least 20,5 % EEG-electricity

2007 we have 16% EEG-electricity in D Source: VDN beim VDEW In 2007 the ordinary electricity in public grids in Germany has 20% renewable electricity In 2007 we have 16% EEG-electricity + 4% from water and bio-waste = 20% in public grids
