Very different from my situation. At high altitude, with roughly 20 frost
days/ year the house is modern, small, well insulated and the heating period
is about 3 months pa. For those 3 months, the total expenditure on natural 
as
and electricity [all purposes] is about $250- $350: two persons. No solar
energy used, that is a hobby thing for the garden and garden workshop.
No more than two snow days pa. Even in midsummer, the outdoors temp may drop
under 10C before dawn but the mid day temp then as high as 38C. Smart summer
move, is to open all windows and doors before breakfast then close same by 9
am.
So you see, there's no interest in domestic co- gen here. But industrial co-
gen has always been a major topic in NSW. Large industry running own gen
stations, are welcome neighbours!
