The annual average electricity consumption of the appliances in a household [kWh/(year∙household)] is the selected parameter for measuring the appliances efficiency. In 2011, the appliances of household consumed an average of 2873 kWh [1].
The values for the appliances electricity consumption are taken from the three scenarios presented in PROGNOS 2012 [1] and they define the max and min values for the appliances efficiency slider.
The evolution of the appliances electricity consumption is expected to be:
| Appliances annual average electricity consumption of a household [kWh/(year∙household)] * | |||||||
|---|---|---|---|---|---|---|---|
| Appliance type | 2011 | 2035 | 2050 | ||||
| 2011 | BaU | PM | NEP | BaU | PM | NEP | |
| Electric stoves and ovens | 401 | 357 | 344 | 344 | 342 | 310 | 304 |
| Auxiliaries for cooking | 307 | 281 | 271 | 263 | 275 | 253 | 242 |
| Appliances (no cooking) | 853 | 604 | 562 | 534 | 580 | 504 | 467 |
