What is one way to increase energy efficiency in household appliances?

1. Using older models

2. Using Energy Star rated appliances

3. Increasing the size of the appliance

4. Using more power-consuming features

The correct answer is: Using Energy Star rated appliances

Using Energy Star rated appliances is a significant way to increase energy efficiency in household appliances. Energy Star is a program that identifies and promotes energy-efficient products, which are designed to consume less electricity while providing the same, if not better, performance as their non-rated counterparts. Appliances that are Energy Star certified undergo rigorous testing to ensure they meet specific efficiency standards set by the Environmental Protection Agency (EPA). By selecting these appliances, consumers can reduce their energy consumption, which not only leads to lower utility bills but also minimizes the environmental impact associated with energy production. In contrast, using older models typically results in higher energy use, as past appliances were not designed with modern energy efficiency technologies. Increasing the size of an appliance doesn’t guarantee better energy efficiency; in many cases, larger appliances can consume more energy. Similarly, opting for more power-consuming features would directly counter the goal of enhancing energy efficiency by increasing overall power usage, leading to higher energy costs.
