4
Basic cause of the increase of atmospheric
CO2 Energetic (and material) use of fossil
(hydro)carbons
5

• 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!)
6

• 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

Climate Protection Activities of the City of
Munich
8
Self-Commitment (Climate Alliance) Minus 10 of
local CO2 emissions every 5 years (with the
only - help of energy conservation and renewable
energies)
9
Local CO2 Reduction Concept
Reference Scenario (21 CO2-Reduction)
Measure Scenario (44 CO2-Reduction)

• Target Scenario
• (60 CO2-Reduction)

Renewable Energies in the City of Munich Facts
and Figures
13

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

14
Water Power Annual production ca. 350 million
kWh (ca. 5 )
15

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
16
Wind Energy
Energetic supply of ca. 1,000 Munich households
(0.03 )
17
Biomass (solid, liquid, gaseous)
0.68 of electricity demand 0.39 of heat
demand
18
Geothermal Energy
Covering the base load of the heat supply of
Messestadt Riem Covering over 50 of the
heat demand of Riem
19
ca. 6 of the total electricity demand and
lt 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)

Activities of the City of Munich to avoid
flooding of the river Isar
22

• 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

23
Water levels of the river Isar (Munich)
outflow daily values (m3/s)
24

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

25

• 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
