During January 2016, the NZERTF consumed 1289 kWh of electrical energy. The solar electric photovoltaic system generated 761 kWh of electricity during the month. The difference between the energy produced by the solar photovoltaic system and the energy consumed by the NZERTF, 528 kWh, was exported to the electric grid. A graphical representation of the energy consumed and generated is found in the year to date results.

The following chart breaks down the total energy consumed by the house into the various end uses. For the month of January 2016 the greatest energy end use was for plug loads followed by appliances. The third largest end use was space conditioning to maintain the house at 70 F +/- 1 F (21.1 C +/- 0.5 C).

A breakdown of the appliance end use into the energy consumed by individual appliances is captured in the following pie chart. During the month of January 2016 the greatest appliance energy usage was associated with the clothes dryer.
