Heat pumps already became popular a long time ago. Electricity is so widely used for heating, that the difference in electricity consumption between the coldest winter days and July nights is almost 2.5x. While there are some old legends of Finnish (or maybe Sami) wind wizards, we still haven't figured out how to generate wind power on demand.

In any case, it's up to the market. If you believe it's possible to make money with wind / solar / nuclear power in Finland, you should be able to get permits in a reasonable time. Right now, those building solar are investing more than the others.
