Nuclear Energy Public Support Remains at All-Time High in Finland
A new survey published at the end of April by Energiateollisuus ry (Finnish Energy) shows that 66% of Finns now have a positive view of nuclear power, while only 8% view it negatively.
This places the current approval rating among the highest ever recorded since the poll began in 1983, just below the record of 68% reached in 2023, and up from 61% in the previous survey of 2024, as shown in the chart below.
The strongest growth in support has been seen among younger people: 59% of respondents under the age of 25 view nuclear power positively, and none in this age group reported a negative attitude.
The shift over four decades is indeed striking: when the poll was first conducted, nearly 40% of Finns viewed nuclear power negatively, while only one in four had a positive opinion.
“Support rose above 60% as we entered the 2020s. This is partly due to the commissioning of OL3, but also because the benefits of nuclear power as a large-scale, stable, and weather-independent form of production are now better understood,”
stated Johanna Aho, Head of Communications at Teollisuuden Voima Oyj (ENS Corporate Member).

In 2024, nuclear power accounted for approximately 40% of the country’s total electricity generation, which is already nearly fossil-free, having reached 96% last year.
Finland currently operates five nuclear reactors in two power plants, Olkiluoto, which produced about a quarter of the Finnish electricity consumption in 2025, and Loviisa.
Looking ahead, the Loviisa plant has already been granted a lifetime extension until 2050, while TVO is currently exploring a further extension of Olkiluoto 1&2 beyond their 60-year design lifetime, with a 2024 environmental impact assessment validated by the Finnish Ministry of Economic Affairs and Employment in October 2025.
