Refrigerators run continuously and maintain a cool temperature, making them the largest energy consumers in most households.

The Energy Star rating is a government-backed program that certifies appliances that meet strict energy efficiency standards.

The energy efficiency of a refrigerator is primarily determined by its size, temperature setting, and frequency of door openings, not by its brand.

The ideal temperature for a refrigerator is 35°F (2°C) for the fresh food compartment and 0°F (-18°C) for the freezer compartment.

Using cold water instead of hot water for washing clothes can save a significant amount of energy.

Air-drying clothes on a clothesline is the most energy-efficient method, as it utilizes natural sunlight and air to dry the clothes.

Induction cooktops are highly energy-efficient as they use electromagnetic energy to directly heat the cookware, minimizing energy loss.

Programmable thermostats can be set to automatically adjust the temperature based on a schedule, leading to energy savings.

Leaving lights on when not in use is a common energy-wasting practice that should be avoided.

Energy-efficient appliances consume less energy, resulting in lower energy bills for consumers.

Electric ovens typically have the highest energy consumption per hour of use due to the high temperatures required for cooking.

Running the dishwasher with a full load maximizes energy efficiency by distributing the energy consumption over a larger number of dishes.

Built-in water heaters are not typically found in energy-efficient washing machines, as they consume additional energy to heat the water.

Using low heat in a clothes dryer consumes less energy compared to higher heat settings.

Energy-efficient appliances typically reduce greenhouse gas emissions by consuming less energy.
