12-Points-Programme Renewable Energy NRW 2020
12 targets
Management by EnergieAgentur.NRW
Monitoring starting 2006 and evaluating the progres,e. g. using indicators
First Report 2010, Final Report 2020
Actually: collecting measures for realization, research project for an evaluation and monitoring concept
Seite 5
Ref. 411Dr. Dagmar Everding30.04.2007
Targets for the industrial sector of Renewables
Turnover increase to 15 Billion Euro
Increase of persons employed to 40,000 Pers.(Pers.employed in NRW: 7.6 million)
Recruitment of companies, research institutes and international institutions
Consulting and training for small and medium companies and for cities administration
Seite 6
Ref. 411Dr. Dagmar Everding30.04.2007
Targets for heating by renewables
Heating supply by renewables:minimum cover ratio 20 %
in new buildings
in reconstructed buildings
In public buildings combined with cogeneration units for heat and power
Seite 7
Ref. 411Dr. Dagmar Everding30.04.2007
Biomass Targets
Biomass Srategy NRW (Ministery of environmental affairs and agriculture)
Increasing the production of heat and electricity using biomass e. g. by the following measures:
Innovative cogeneration plants for heat and power using biomass
Development of bioenergy villages (self-sufficient)
Support of new biofuel plants in NRW
Seite 8
Ref. 411Dr. Dagmar Everding30.04.2007
Research Targets
Support of technology development:
Energy efficiency, cost reduction,
energy grids, energy storages and batteries,
hydrogen technologies (e. g. using clearing sludge) (Energy Research concept NRW, Ministry of research and innovation)

50 Solar Energy Housing Estates Example: New Building Project, Aachen
Passive Houses with solar thermal collectors
Measured heat demand: 10.6 kWh/m²a,Total: 1.700 kWh/a
Less than energy demandfor domestic hot water!
Comparison to heat demand of a conventional house: 11.000 kWh/a(Passive house: -85%)
