Abstract:
The aim of this investigation is to determine environmental aspects of(1) upscaling of both onshore and offshore turbines and (2) offshore versus
onshore placement of turbines. Attention has also been paid to a couple of
waste processing options in order to obtain a responsible disposal of
dismissed wing blades of wind turbines. Shortcomings of the followed
procedure for life cycle assessments are pinpointed in the field of the
software package, the inventory and the normalization of effect scores both
for classification and evaluation. Upscaling from a 300 kW wind turbine to a
500 kW wind turbine results in a decrease (20-50%) of all environmental
impacts considered in this study both for an onshore and an offshore
situation. This is caused by the fact that the increase of materials use
turns out to be lower than the increase in energy production. However,
smaller differences than assumed in this study in electricity production
between the two types of wind turbines - depending on wind climate and design
- will result in a lower decrease or even an increase in environmental
impacts. Offshore placement leads to considerably higher environmental
impacts compared to onshore placement (5-180%). However, offshore placement
offers important advantages in the field of noise pollution, adverse effect
on landscape and level of electricity production. 11 figs., 25 tabs., 41 refs.
