What is one disadvantage of using high-power appliances?

High-power appliances are designed to consume a significant amount of electricity, which directly leads to increased energy consumption. This higher energy usage results in elevated electricity bills for consumers, particularly if these appliances are used frequently or left on for extended periods. While there are advantages to using high-power appliances, such as efficiency in task completion or performance, the downside is the additional financial burden due to their energy demands.

The other options present characteristics that do not typically align with high-power appliances. For instance, they often have higher initial costs rather than lower, and while some may require less frequent maintenance, this is not universally true. Insulation is unrelated to the power consumption of appliances, and generally, high-power appliances tend to require careful consideration of energy use.
