SELF-SUFFICIENT FOR SURVIVAL
SHOULD Linda and Nevin Sweeney ever be confined to their home, they could survive comfortably for months, thanks to their assortment of crops and many sustainable features installed over decades. “I would like to say indefinitely, because we save our own seeds and all that sort of stuff, but along the way there’s little inputs you don’t realise you need,” Mr Sweeney said. “We would be able to have a reasonable – if not, a little bit deficient – protein diet for somewhere between six to 12 months.” He said in such a scenario, the couple would limit their electricity usage, made easy by their 10 solar panels, 12V system, one kW back-tothe-grid system and solar oven. The couple’s latest electricity bill came in at less than $30 for the quarter. And they were using 3kW hours a day, significantly less than the average 14 to 16 for a twoperson family, Mr Sweeney said.
