Some of the costs and benefits of renewable energy that have been identified to date have yet
to be quantified. This is true, for example, of their importance for internal and external security.
In view of the wide range of effects, it is of central importance that quantitative comparisons
are only possible within the individual main effect categories. The most useful approach
to this to date is a systematic cost-benefit analysis.
A rough calculation of the existing quantitative system costs in the heat and power sectors
reveals total costs of just under 10 billion EUR for 2010. In the same year this was offset by a
quantified gross benefit of approx. 8.5 billion EUR, though only some the benefit effects were
quantified, while others were not taken into account (e.g. the lower risk potential of renewable
energy sources). This statistical view of costs in 2010 therefore has to be supplemented
by additional (especially dynamic) benefit effects such as spill-over effects of political and
R+D activities, technical progress and increased (supply) security, which cannot at present be
quantified in monetary terms. Here, as in the other categories, there is still a considerable
need for research. In view of the significant benefit items, it is nevertheless evident that an
analysis of the expansion of renewable energies that is based on costs alone falls considerably
short of the mark.
The following table once more provides an overview of the main cost and benefit effects currently
known for heat and power generation from renewables.
