Four European countries have demanded that the EU grant nuclear energy a similar status to that of solar and wind energy. Ultimately, this could lead the EU to pay billions of dollars to subsidize nuclear power.
Subsidies are supposed to be a Pigouvian tax, which cover this activity's negative externalities. However, with the high costs associated with following the demands of these four countries, it is just not practical to regard nuclear energy as a renewable energy source.
In fact, other countries, such as Germany, have learned their lesson and are trying to avoid disasters such as the one in Fukushima by trying to ween themselves off of nuclear energy completely. Germany intends to shut down all of its nuclear power plants, which is estimated to occur by 2022.
