Most of the electricity in Finland is not produced by using fossil fuels. For example during year 2020 14 % of the electricity in Finland was produced by fossil fuels.
I was talking about energy intensive industries, not electricity production. If Finland has to compete with other countries that have cheap renewables, it will lose these industries. As an example of something like that today, look at primary aluminum production.

There are 31 countries on that list, from China to Venezuela. Finland is nowhere on there.
In the all-electric economy of the future, every energy intensive manufacturing activity will start to look like aluminum production.
