As other say: it is converging to Hawaii-prices, but most of that is Taxation. In Denmark, the policy has been to put taxes on resource usage in the later years and not only on income. In this case the resource usage is on fossil fuels.

The slight problem with that model is that in principle, it should be cheaper when the energy is green, and more expensive when it is not. But the state has come to rely on the tax, so now it is a bit murky what it is really for.
