Because those decisions are made at the country level. People keep speaking of the EU as if it had the authority of a country. It does not. While it was empowered by the members states to regulate certain things, a lot of things come down to each individual country. Pointing at the EU is a way to launder the failures of each country. For instance, while there are regulations on emission reduction and percentage of renewables, how those are achieved is on each country. It was not the EU that made Germany retarded with nuclear. If anything, the EU regulation on emissions reduction and renewables make the countries here slightly less dependant on oil and gas. For the EU to make the "hard decisions" that would allow it to be relevant in the global stage, it would need to federalize. Become a de-facto country.
