I would like some evidence that 80% of domestic use is for heating water. I
would suspect that heating the house in the southern states takes a lot more
energy and cooling the house in the northern states (and southern states
summer) would also take a fair chunk. I just evaluated solar hotwater for my
wife and myself in Melbourne and the %age of our gas bill (let alone our
total energy bill) that it would save was pretty small.
