| Zusammenfassung |
| Sufficient energy access is essential for development and adequate
livelihood conditions, as the majority of societal activities depend on
reliable and sufficient energy. Especially in developing and threshold countries,
energy access remains limited and intermittent. Moreover, compared to developed countries, often the expenditures for energy constitute a huge part of the available money.
The vulnerability of energy systems to the impacts of climate change
differs depending on the utilized source of energy. A special characteristic of developing and threshold countries is the fact that the spatial heterogeneity of the energy supply structure, especially between urban and rural regions, is generally larger than in developed countries, while the adaptive capacity of people is often much lower. A sound consideration of these complex conditions is a necessary basis for determining in how far climate change impacts can further diminish energy access in regions, where energy access is already limited.
The topic of energy vulnerability has often been addressed for developed
countries, but assessments for less developed countries remain scarce. On
the one hand, data needed for energy vulnerability assessments, as they
exist for the developed world, is usually not available. On the other
hand, existing assessment methods for the developed world are often not
transferable because they focus on specific supply infrastructure or energy
carriers. Transferability is also hindered by the large differences in energy access and energy use
patterns.
We propose a novel approach to assess domestic energy supply
vulnerability, by reversing the usual chain of assessment. On the basis
of a basket of household energy needs for different purposes, we first
assess which sources are used in order to fulfil specific energy needs.
By focussing on the regionally specific energy carriers, we are able to
significantly reduce data needs and assess directly, how energy
vulnerability may play out in a specific context. Using Sankey diagrams
to visualize energy flows, the method allows identifying household
reliance on specific energy carriers. The approach provides a basis on
which to identify specific patterns of vulnerability as well as existing
limitations to energy access. Finally, options for a pathway towards
reliable as well as sustainable energy access can be assessed. We will
present the conceptual basis of the approach and show a first
implementation for two case study countries. |
