Project description

According to statistics the electrical energy consumption in the domestic sector has risen significantly for more than two decades. Within 1990 and 2006 household power consumption increased by 30 % despite considerable gains in energy efficiency at the same time. This was for several reasons – first of all raised saturation levels (number of appliances per household) as well as demographic trends were effective as main influencing factors.

An enormous energy efficiency increase plays a crucial role in all scenarios in the context of energy politics. It’s undoubted amongst experts that a detailed examination of the recent domestic power consumption trend is urgent. Although the complex background for people’s behavior is challenging indeed – economical consideration opposes cultural and psychological aspects in a synchronous way.

Instruments, which are designed for reduction of energy consumption, are applied in a demanding and hardly controllable arena. Moreover already existing studies contain quantitative data only in a very poor resolution.

Primary aims and content of the project:

  • Target as well as primary result of the project is an assumption for the trend of domestic power consumption in the period 2010 to 2030, reflecting different structural types of households. Based on a qualitative and quantitative analysis of electrical power consumption in this sector serving as a description of the status quo the most relevant influencing factors are evaluated in the context of socio-economic aspects and life style concepts. These factors, e.g. energy consumption per category, specific energy consumption, demographic aspects, wealth level, energy efficiency, tariffs, market offer, saturation levels, needs as well as demand for services, and their dynamic evolvement are assessed in a holistic approach. Consequently valid outcomes for policy design processes can be provided in order to reduce power consumption enduringly.
  • A direct involvement of stakeholders is a precondition for a successful implementation of the project’s outcomes. This will be done on different levels within the project.
  • Resulting from an assessment of existing and expected energy efficiency potentials for several technologies in the domestic area the most likely paths will be identified. This will be supplemented by a fundamental exploration of the area of conflict “needs and related solutions on technical level”. Potential users will be involved to identify and develop more sustainable innovative concepts.
  • The development of different scenarios, based on participative methods for stakeholder involvement (Delphi scheme), will support establishing a dynamic bottom up model for assessing energy consumption trends in the period of 2010 to 2030.
  • In an open discussion with stakeholders sensitivity analyses will be accomplished to debate critical paths. The following parameters will be considered amongst others: changes in climate, variation of tariffs, demographic trends, saturation levels, etc.
  • Following the analysis of scenarios and the evaluation of possibilities for interaction the main focal points for a sustainable transformation of the subsystem domestic electricity use will be identified. As an important result from the project a catalogue of appropriate measures on national level will be elaborated. This catalogue will comprise hierarchized activities, which are synergetic or complementary to actual and upcoming EU policies.
