Yes full log built houses are made here as well, but not just with the log except for summer houses, usually there's a foot of insulation to boot. My summer house is built of solid logs a foot thick but you can't really stay there in winter as it has no other insulation than wood and only twin plated windows too. Wood is what we have plenty of here indeed, I myself probably own a thousand pines and spruces, birches and such...impossible to count of course. How many trees are there in a couple of hectares of woods? I've no idea.
My house was made in 53' and it's been renovated, and it's built of wood - not solids - but there's nearly dozen layers of wood and insulation; from inside it goes like : gypsum sheet, moisture seal (aluminum sheet), wood plank layer, 4 inch wood bars every two feet with the gap in between filled with sawdust, another layer of wood planks, a ventilation gap, a third layer of thicker planks (about an inch thick, then another 4x4 support stucture now layered with 4 inches of glass fibre insulation, then a thick kind of woollen type but hard windbreaker layer, then a wood wall with an air gap, then the outer wall.
For electricity, including heating, my bill is about $3200 per annum, but I also use wood to burn for which I spend ~300 more per year. Somewhere around 25.000 KW/h I believe off the top of my head for electricity, and the biggest bulk of it is of course heating...so I'd say three grand a year is a good estimate for heating costs.
