Belief in the possibilities of utilising alternative energy continues to be strong in all circumstances. Significantly many (45%) consider the pollution-free and inexhaustible solar energy to be a realistic solution in the near future. Those who expect a long waiting period are also numerous (32%). The time series of these estimations is harmonious. Optimism regarding the possibility of using solar power increased with fairly steady, albeit short, steps for a long period. At the turn of the millennium the development stopped and attitudes started to gradually change back towards scepticism. The share of sceptics did not increase in the previous survey, and the current results indicate a new growth in optimism regarding solar power [Figure 22.].

Seven out of ten (70%) believe that wind and solar power could be taken into extensive use in Finland fairly soon, if there were willingness to invest in the research and development work on these technologies. Only a few (12%) deny the truthfulness of this. An alternatively minded, but extremely technological, belief gained strength steadily over a period of several years until 1998, after which the trend broke and opinions started to become slightly more cautious again. Belief in alternative energy is now on the same level as in the previous survey, and close to the average of several years before that [Figure 23.].

Attitudes towards wind power were tested with a separate statement, in addition to asking about the desired extent of the use of this energy form (see Chapter 1.). Referring to this energy form's negative effects on the landscape does not noticeably alter the sympathies of the general public. Slightly fewer than one in four (23%) now agree with the opinion that an increase in the use of wind power would result in considerable environmental harm, with wind farms spoiling the scenery in extensive areas. Even though this figure is now slightly lower than in the previous year, the time series of eight surveys indicates a growth rather than a decrease in scepticism. It is possible that with time, people start to see problems even with wind power. Few people are still likely to have personal experiences of the aesthetic nature of wind farms [Figure 24.].

A new statement measuring attitudes toward utilisation of waste was included in the current study. Even though this is not alternative energy in the traditional sense, the public discussion on the treatment of waste largely follows the same division as attitudes toward alternative sources of energy. The thesis 'Burnable domestic and other municipal waste should be burned in waste burning plants rather than attempted to be utilised in some other way' was supported by as many as seven out of ten respondents (70%). Only about one in ten (9%, no figure) dare to disagree. When interpreting this extensive consensus, the lack of contradicting arguments as well as the practical problems in organising the burning of waste must be considered. Approval may subside quickly when the question of waste burning plant locations is raised (the so-called NIMBY syndrome).
