Wind turbines are possible but will be limited by conditions such as air traffic (Schiphol airport is nearby), nature and landscape conservation, and lack of space. Only a few small turbines in rural areas are likely to be possible. This means that solar energy provides the best possibilities, although limitations to this are also imposed by nature areas, cultural heritage and lack of space. The regional study concluded that given the limitations, Hillegom will be able to meet no more than 40% of the energy demand by exploiting sustainable energy sources. What did the SEA address? The SEA sketched the outline of the risks and opportunities caused by the strategic “direction” laid down in the draft environmental strategy for seven subareas and two themes. The SEA showed that on the one hand, there are several options for improving physical environmental conditions, such as improving environmental quality in urban areas by relocating industries. On the other hand, it 28 The NCEA’s Views and Experiences 2018
