Here in Norway electric blankets are unheard of. I've only seen them as a child, visiting my grandparents in the States. Down "dyne" all the way! I don't know if that's a duvet or a comforter, it's downfilled, puffy, and has a washable cover. We have a lightweight summer one and a heavier winter one which can only be used in the coldest winter months. My solution for freezing sheets in winter is to toss in an oldfashioned hot water bottle a little while in advance.
