The Sweden's problem came to light a few weeks ago. The harshest winter in several years caused the authorities to decide to launch a backup heating oil power plant in Karlshamn in the south of Sweden. A decision was also made to import "dirty" energy because its source is, among others, coal, from Poland, Germany, and Lithuania.
"How will an industrial nation in northern Europe survive if we cannot produce enough energy to survive a normal winter?" - asks Christoffer Heimbrand, a politician from the party which was against shutting down nuclear power plants.
At this moment, in Sweden, any cold day without wind can be a disaster.
