Sweden, a member of the European Union, with the highest percentage of renewable energy, Sweden has 29 beautiful national parks and 4,000 nature reserves. The country’s progressive policy is also reflected in its higher education system. Tuition is free for all PhD students in Sweden, and scholarships are available to cover living expenses. Eight Swedish universities are among the top 350 in the QS World University Rankings, including Lund University, which is ranked 92nd in the world.

And at the end of our look at affordable European study destinations for PhDs, we come to Norway. Studying in the public universities of this northern European country is free for all students regardless of nationality, and you only have to pay a small fee to the student union to cover the cost of student facilities. Of course, like all Nordic countries, the cost of living in Norway is still high. Academically, there are four Norwegian universities in the QS World University Rankings, with the University of Oslo ranked 135th in the list.
