Electricity-price sensitivity
| Electricity price | Energy/use day | Annual energy | Annual cost |
|---|---|---|---|
| 15p/kWh | 1.20 kWh/day when used | 187 kWh/year | £28/yr |
| 25p/kWh | 1.20 kWh/day when used | 187 kWh/year | £47/yr |
| 35p/kWh | 1.20 kWh/day when used | 187 kWh/year | £66/yr |
Important assumption
Low power for a long time can still use less energy than a high-power oven, but recipe and duration determine the comparison.
This is a worked planning estimate, not a measurement of your appliance. A smart plug, energy monitor or manufacturer annual-kWh figure usually gives a better real-world input for cycling appliances.
