How about those big masonry stove things that burn wood? Much used in northern Europe, apparently. Those are supposed to be very efficient, and handy for people in remote rural areas.

Nuclear power, of course is the ultimate non-carbon generating power source...

"Kaminofen", as we say here in Germany. Very popular in summer houses asn country areas. You can get all sorts of recycled sawdust "bricks" to use in them (Sadly, in Germany a lot of "brown coal" (shale coal) briquettes are also used).
