Which of the following actions can help reduce energy consumption in homes?

Using energy-efficient appliances can significantly reduce energy consumption in homes. These appliances are designed to use less electricity or gas while providing the same level of performance as their less efficient counterparts. For example, Energy Star certified appliances consume less energy, which not only lowers utility bills but also reduces the overall environmental impact by decreasing greenhouse gas emissions. Homes equipped with energy-efficient appliances typically demonstrate lower energy use, making them a wise investment for both homeowners and the planet.

In contrast, leaving lights on in unoccupied rooms leads to unnecessary energy expenditure, as does keeping windows open in winter, which can result in heat loss and increased heating costs. Traditional incandescent bulbs are less energy-efficient compared to newer technologies like LED or CFL bulbs, consuming more power for the same amount of illumination. Therefore, investing in energy-efficient appliances is a proactive way to promote energy savings and enhance overall household efficiency.
