> Sweden is moving to greener energy and is currently exporting electricity to Germany and Poland. How come it works here but not down there?

Sweden has 3.5x more hydro than wind energy (in TWh produced). Germany has 7x less hydro than wind. Sweden can easily use their large hydro reserves to balance out the fluctuations in wind power output.
