Ortogonal to the discussion, but I think in an odd way, Australia is one of the most similar countries to Spain in this aspect. Very limited to no natural gas proliferation, electric heating, if any, but houses made rather cheaply but somehow still ending very expensive. I've seen houses near Melbourne resembling a tin hut costing AU1.5M. According to weatherspark, some Spanish locations have their climate counterparts in Australia, e.g. Perth is most similar to Malaga.
