The Australian Greenhouse Office much less, 28% of domestic use. The
reduction in greenhouse gases in switching to solar hot water is said to
be 50-90%.  But I think this would be optimistic if comparing efficient
gas to solar hot water in a southern state + there will be a higher take
up of solar already in northern areas where it is most effective.

I think domestic use is about 10% of total greenhouse emissions so
maximizing our use of solar how water might reduce greenhouse emissions
1-2%.
