What I think you mean is that politicians have spoken and the market saw the open coffers and took advantage of that.
If I go to the market and ask for 240TWh of stable energy each year (Danish electricity consumption), without any carbon-based sources as backup, which technology will provide that the cheapest?
Oddly enough, electricity is 50% more expensive in windmill-rich Denmark, than nuclear and hydro-powered Sweden. One wonders what the market is trying to tell us Danes...
