Ever wondered what really gets your power meter spinning? We took the power bill for an average New Zealand house, broke it down into six parts, and identified just where the money had been spent.

Two adults and two children live in this all-electric, well-insulated, suburban Wellington home. The time of year is autumn/winter.
