Question: 1 / 400

How do energy-efficient appliances contribute to sustainability?

By increasing energy consumption

By reducing greenhouse gas emissions

Energy-efficient appliances contribute to sustainability primarily by reducing greenhouse gas emissions. These appliances are designed to use less energy while performing the same functions as standard appliances. This lower energy use means that less fossil fuel combustion is required to generate electricity, which in turn decreases the amount of greenhouse gases released into the atmosphere. Over time, widespread use of energy-efficient appliances can significantly mitigate climate change impacts by lowering overall carbon footprints.

In contrast, options that imply increased energy consumption, higher utility costs, or greater water usage do not align with the purpose of energy-efficient technologies. The goal of such appliances is to optimize their energy use, thereby making them environmentally friendly and economically viable in the long term.
