Chances For Communities ? !

1. „century task“: energy

2. strategies for communities

3. chance: independence

4. chance: value creation

5. chance: co-operation

Communal concepts for renewable energies



The century task



Development of world energy consumption

2010

firewood

water power

nuclear energy power

coal

gas

oil

[year]

12.000



Chance: independence



6

Nitsch, u.a. 2006

essential elements:

reduction of conventional energy sources by 51%

extension of renewable energies to 49%

reduction of energy consuption by 45%

strategie for germany

energy efficiencygeothermal

solar energy

wind, water power

biomass

natural gas

mineral oil

black coal

brown coal

Nuclear power



CO2-neutral energy supply

Long-term communal strategy climate protection

and services for the public

Avoiding CO2 emission

Renewable energies

Fundamental communal strategies



chance: regional value creation



depreciation of households

energy costs 1.250 € (per inhabitant/ per year)

Oil and natural gas asmain energy sources

only 15 % value creation remains (35 % in germany)

costs for fossile energy sources are not available for regional consumption and for investments

example „Baunatal“ (28.000 inhabitants, reduction of energy costs by 50%):

about 600 € per inhabitant x 28.000 inhabitants : => about 16,8 Mio. Euro per year available assets more !

materials and energy flows

capital flow



nowadays

loss in buying power and global division of labour

value creation i.e. in Dubai already visible

future

Regional value creation and personal involvement

value creation (jobs) on location

structural change in the field of energy efficiency and power reduction offers big chances in regional development



chance: co-operation



consulting

funding

motivationinformation

qualifikation

communication

success depends on a good co-operation !

example: communal operating company for photovoltaic plants

• Share holding of the citizens in regional energy production

• All citizens can profit from revenue of the plants

• Collective acquisition

• Collective operation

example: communal biomass firing

Oberrosphe Oberrosphe:rural area about 830 inhabitants about 240 households 122 joined the projekt

Central biomass boiler (wood chips) power: 850 kW



example: inter-communal co-operation

KlimaX: invitation für second meeting of communal regulation teams



European co-operation ?

We are interested in co-operation with european partners:

• to develop common projects

• to speed up the implementation of processes

• to learn from each other

• Dämmung Kellerdecke 6cm WLG 035

• Zusammenfassung 3 Südgauben, Flächengewinn für Solarkollektor

• Solarkollektor ca. 15m² für Warmwasser und Heizungsunterstützung

• Kombispeicher ca. 900 Liter und Gas-Brennwerttherme

• Barrierefreies Bad im EG

• Lüftungsanlage (Abluft)



Kosten / Finanzierung

• Gesamtkosten: ca. 130.000 EUR

• „Energetische Kosten“: 70.000 EUR

Finanzierung

KfW-Kredit: Energetisch SanierenZinssatz Stand: 26.06.2009: 2,12% Kreditlaufzeit: 30 Jahre + Zuschuss von 12,5% zur Reduzierung der Annuität.

Finanzierung „Energetische Kosten“: Zins- und Tilgung: 247,84 EUR / MonatEnergiekosten vorher: 25l/m² x 230m² = 5.750 Liter pro Jahr Energiekosten nachher: 5l/m² x 230m² = 1.150 Liter pro Jahr

Mittlerer Ölpreis der nächsten 10 Jahre: 70Ct / Liter (aktuell: 55Ct / Liter)

Ersparnis: 4.600 Liter x 70 Ct = 3.220 EUR/a entspricht: 268,3 EUR / Monat

Zusätzlicher Effekt: extrem günstige Finanzierung der Gesamtmaßnahme
