Here's a wacky question:
" instead of trying to live off the Electricity Grid, (-by installing lots of PV Cells and huge back-up batteries...etc etc)
-How would you go removing yourself from The Gas Grid?
Have just noticed that for a quarterly use of only 1148 MJ (costing $47.26), I'm paying a whopping $78.08 in supply charges
Wouldn't it be cheaper to convert my appliances, switch to bottle gas, and then put the savings into a really efficient hot water system like the new Schott Evacuated Glass Solar collectors?"
Does anyone out there have any background knowledge on this?
