However, there is a tax on nuclear fuel which is equal to 80 times the worth of the fuel itself. Some regional courts have ruled it unconstitutional. Proceeds from the tax are used to finance subsidies for the competition (coal and renewables).

You pay an addtional surcharge on all electricity you buy, but only the 'green' producers get this money, regardless of where your electricity really comes from.
