One of the interesting things about life in Siberia is the prevalence of 
district heating systems, where an entire neighborhood or village is 
heated from a central plant.  While I am certainly not an expert on the 
subject, my reading is that such systems are more efficient than the 
typical modern house which has its own individual heating system.  One 
of my thoughts about urban permaculture is that district heating and 
cooling systems, coupled with superinsulation and other passive systems, 
would be a useful way to lower the energy consumption of cities.  To 
some extent, this happens in central business districts, where there is 
often some form of district heating or cooling available.  Downtown 
Oklahoma City has that "amenity".
