english: It's going to really require a national energy policy, frankly for each country, because the solutions in each country are going to be different based upon income levels, traffic jams and also how integrated the systems already are.
non_english: To će stvarno zahtevati nacionalnu energetsku politiku, za svaku državu, zato što će rešenja u svakoj državi biti različita na osnovu nivoa dohotka, saobraćajnih gužvi i koliko su sistemi integrisani sada.
