Charmaine Watts hasn't had a power bill for eight years.Her family of two adults and three children are one of hundreds around the country generating their own electricity.
With power prices on the rise, the $20,000 the Watts spent installing solar panels, a small wind turbine, storage batteries and wiring is starting to look like a good investment.
"I don't need to worry about power cuts," said Ms Watts. "It's just like a normal house. I flick the switch on my computer or my DVD player and away I go."
