Presentation Transcript

Slide1: 

The local contribution of the City of Munich against climate change and its impacts. CEMR Seminar Climate Change Brussels Joachim Lorenz City of Munich

Slide2: 

T source: D. Meadows The Causes for Climate Change

Slide3: 

source: D. Meadows

Slide4: 

Basic cause of the increase of atmospheric CO2: Energetic (and material) use of fossil (hydro)carbons

Slide5: 

Sustainable measures and technologies to bring down CO2 emissions: Saving energy More energy efficiency Utilisation of renewable energies (Nuclear energy and CCS technology are not representing sustainable technologies!)

Slide6: 

Instruments of local authorities for better energy conservation and renewable energies legal frame conditions financial and organisational support for individuals and companies guidance in energy and building issues acting as a model building insulation/refurbishment conservation of electricity offering (utilities) and/or utilisation of RE

Slide7: 

Climate Protection Activities of the City of Munich

Slide8: 

Self-Commitment: (Climate Alliance) Minus 10 % of local CO2 emissions every 5 years (with the – only - help of energy conservation and renewable energies)

Slide9: 

Local CO2 Reduction Concept Reference Scenario (21 % CO2-Reduction) Measure Scenario (44 % CO2-Reduction) Target Scenario (60 % CO2-Reduction)

Slide10: 

Development of CO2 emissions in municipal buildings

Slide11: 

Subsidy Programme for Energy Conservation

Slide12: 

Renewable Energies in the City of Munich: Facts and Figures

Slide13: 

Water power Solar energy Photovoltaics Solarthermal energy Wind energy Biomass Geothermal energy

Slide14: 

Water Power Annual production: ca. 350 million kWh (ca. 5 %)

Slide15: 

Solar energy – PV and solar thermal ca. 20 million kWh (0.1 %) of end-energy (electricity + heat) are produced by solar plants in the city

Slide16: 

Wind Energy Energetic supply of ca. 1,000 Munich households (0.03 %)

Slide17: 

Biomass (solid, liquid, gaseous) 0.68 % of electricity demand 0.39 % of heat demand

Slide18: 

Geothermal Energy Covering the base load of the heat supply of „Messestadt Riem“ Covering over 50 % of the heat demand of Riem

Slide19: 

ca. 6 % of the total electricity demand and < 1 % of the total heat demand are presently produced on the basis of renewable energies. (based on national figures (2005): 10.2 % and 5.3 % resp.) Aim 2020: 1,500 GWh (min.) green electricity production (at present: 350 GWh)

Slide21: 

Activities of the City of Munich to avoid flooding of the river Isar

Slide22: 

Background: Mid of the 19th century: Canalisation of the river Isar to enable electricity generation Climate change Risk of floods 1959: construction of the Sylvenstein reservoir in the Alps for the regulation of the outflow to avoid flood water

Slide23: 

Water levels of the river Isar (Munich) – outflow: daily values (m3/s)

Slide24: 

Isar plan flood protection more orientation towards nature higher quality of recreation

Slide25: 

Measures: Widening of river bed Lowering of steep banks Construction of gravel islands Broadening, raising and reshaping embankments Cultivating meadows between river and embankments Renaturalisation

Slide26:
