How to lower the cost of running a rice cooker
- Turn off keep-warm once the rice is done. Over several hours it can use more than the cook itself.
- Cook larger batches and refrigerate leftovers.
- Use the quick cook mode if your cooker has one.
In standby it draws about 1 W, which adds roughly 9 kWh (C$1.46) per year if it is never unplugged.
