A convection microwave typically uses more electricity than a non-convection microwave. This is because convection microwaves incorporate additional features, such as a built-in fan and heating elements, to circulate hot air and provide even heat distribution. These added components consume extra energy.
The exact energy consumption of a microwave depends on several factors, including the power rating of the appliance, the cooking time, and the specific settings used. However, in general, convection microwaves tend to consume more power due to the additional functionality they offer.
To get a more accurate estimate of the electricity usage, you can refer to the energy specifications provided by the manufacturer of the microwave model you are interested in. The specifications typically mention the power consumption in terms of watts or kilowatts. By comparing the power ratings of different microwaves, you can gauge the relative energy consumption between a convection microwave and a non-convection microwave.
