Commentary:
The increase in specific emissions is attributable to
our commitments in Germany’s eastern states.
The lignite-fired power station in Lippendorf operated
for a full year for the first time in 2000.

Water output
Coolant water intake l/kWh 59.759
Evaporation water l/kWh 1.369
Direct intake l/kWh 0.017
Waste water l/kWh 0.011
Commentary:
As a result of the modernisation of the cooling
towers at the Heilbronn and Philippsburg sites in
2000, both the overall volume of waste and the
quantity of waste requiring disposal increased substantially.
