Prioritization of the individual measures within the energy sector
The biggest short-term and medium-term CO2
reduction effects at constant use of resources can be achieved through
- the reorientation from solid and liquid fuels to natural gas or district heating in already developed areas
- the introduction of combined heat and power systems (only when the energy mix for the whole of Germany is taken into account)
- the use of energy saving lamps
- the use of waste heat
- the use of wind energy and biomass
- the modernization of heating systems.
It becomes clear that the assessment of the saved electricity is significant for the result when it comes to measures aiming at the saving or production of electricity.
Measures supporting the use of solar energy and the efficient insulation of buildings have the highest specific values for both investments and funds. The priority among insulation measures lies in the damming of basement and floor ceilings.
At our current energy prices, almost none of the measures achieve the efficiency limit. Only the use of energy saving lamps and wind energy (provided that the current law on inputs of electricity to the grid is maintained) exceeds the efficiency limit.
What also plays an important role are measures aiming at removing obstacles which prevent the implementation of energy efficient measures and amplifying the effects of measures in the fields of heat insulation (E1.1), the modernization of heating systems (E2.1) and substitution effects (E3.1).
For this purpose, the central focus is put on the recommended analyses concerning the rational use of energy by industry (E2.2, E2.5), expansion potentials of the energy services provided by TWS (E4.1, E4.2), measures regarding city-owned buildings (E4.5, E3.7) and development areas (E1.4, E1.5), which can be directly initiated by city authorities as well as the increased use of renewable energies.
