The report, produced by the Finnish Meteorological Institute (FMI), advocates fresh consideration by government agencies and planners to building a greater number of turbines in hilly inland areas with an altitude of 100-150 metres.
The FMI wind-mapping survey is part of a government programme to identify optimum sites for wind parks, onshore and offshore, in Finland. FMI concludes that Finland has the potential to develop up to 15 GW of wind power using both onshore and offshore sites.
"In inland areas, if you build modern turbines in areas that are high enough, you will get wind conditions similar to those on the coast," says Bengt Tammelin, the FMI's development manager. Under the government's current plan, Finland is aiming for 2 GW of new wind capacity by 2020.
Wind power has been rated second after nuclear energy as the most popular solution to Finland's national long-term energy self-sufficiency needs, according to a TNS Gallup poll.
The survey finds that 31% of Finns favour construction of additional nuclear power capacity, while 25% favour wind. The shares for nuclear and wind show a slight drop compared to a similar survey conducted in April.
The sharpest increase in preference related to bio-energy, with 22% of those surveyed supporting the construction of more bio-energy production plants, up four percentage points on the April poll.
