Breakdown of Alex's energy use

This pie chart shows the percentages of Alex's total energy consumption of broken down by the metered appliances.

The tumble dryer, washing machine and dishwasher were monitored over a two week period and the energy consumption measured. The fridge-freezer, computer and TV were monitored over a 12 hour period and the energy consumptions scaled up. The 'always on' was calculated by measuring the minimum power demand, subtracting that of the computer, and calculating its consumption scaled up over the period. The consumption of all remaining appliances was calculated by subtracting the consumption of each of these categories from that of the household.

These values are similar to what you'd expect from an average household.
