So your total daily energy use including water heating is only 8.17kWh compared to my household's 14.9!<BR/><BR/>That's a good example of how much more efficient gas is for hot water and cooking compared to electricity, in terms of absolute energy usage. Though if my electricity were generated from solar panels or a wind turbine it would be more sustainable than even natural gas.<BR/><BR/>I'm <I>so</I> itching to ditch my electric hot water system and put some nice black panels on my roof.TBhttps://www.blogger.com/profile/08364685562037692444noreply@blogger.comtag:blogger.com,1999:blog-6164913240597091741.post-62714035193828451782007-05-15T19:12:00.000+10:002007-05-15T19:12:00.000+10:00Water: 220 litres per day.Electricity: 6.5kWh/day ...Water: 220 litres per day.<BR/>Electricity: 6.5kWh/day on Tariff 11 (no other meters).<BR/>Gas: approximately 6 megajoules per day.<BR/><BR/>Two adults (and one dog :) ) using the above.

Unfortunate, but we're still well below the 150 or so litres/person/day Brisbane's currently seeing.Iainhttps://www.blogger.com/profile/01490549114541000348noreply@blogger.com
