In Tanja Männistö´s Master´s Thesis (University of Jyväskylä) the main objective was to discover if first-hand experience of a wind farm influences the general attitude towards wind energy. Central Finland´s first wind farm was constructed in Latamäki of Luhanka in the summer 2014. There are six 3 MW wind turbines in Latamäki.
First survey to inhabitants was conducted in April 2014. The second survey was send to the respondents of the first one in January 2015 about five months after the construction of Latamäki wind farm. The sample consisted of 10 % population of Luhanka.
Prior to construction of Latamäki wind farm, inhabitants held mainly positive attitudes towards both wind energy in general and Latamäki wind farm. After the construction of the wind farm inhabitants were still in favour of Latamäki wind farm. Moreover, attitude towards wind power in general as a form of electricity production had become more positive. Respondents had also changes their attitudes on how they perceived impacts on nature caused by the wind power production. Related to the latter, women and people, who had not seen wind turbines prior to the ones constructed in their own municipality, changed their opinion more than men and people who had seen wind turbines before.
