What is the consumption in kW/h for a typical NZ home?
This is a difficult question to answer as it depends on a number of factors such as the type of house, size, number of people living in the property etc. As a very rough estimate a typical NZ home with 2 adults and 2 children would consume between 15 and 28 kW/h per day.
Nevertheless large modern open plan homes with pool, aquarium and down lights can easily use between 40 and 50kW/h per day with some households using as much as 60kW/h of electricity per day. A highly energy-efficient home with energy efficient appliances, a net meter and solar power system can use as little as a 5 -10 kW/h per day.
