The details of the technologies assessed are shown in Table 1. Discussion of burdens and impacts Noise from the wind farm is a burden to the residents and other people in the area close to the wind farm. As Tun Knob wind farm is located at sea 3 km from land the noise effect is negligible. Still, as noise is the most discussed burden in relation to wind energy this burden is given high priority. Also in the case of Fjaldene wind farm the assessment of noise is quite important.
Visual intrusion is a burden for residents, visitors, travellers and others near the wind farm.
The region of Tun Knob is a popular one for summer residents and visual intrusion is therefore a burden that has caused a lot of discussion. The visual burden has been given a high priority. There are no atmospheric emissions related to power production using wind turbines. However the production of materials for the wind turbines will cause atmospheric emissions. Coal and natural gas, causing emissions of SO2, NOx, CO and particulates will mostly produce the materials.
