Air conditioners are known to be the most energy-intensive appliances in a household, especially during hot summer months.

The main advantage of energy-efficient appliances is their ability to consume less energy while performing the same tasks as traditional models.

The Energy Star rating is a government-backed certification that indicates a product meets strict energy-efficiency standards.

The EnergyGuide label provides information about an appliance's energy consumption and estimated annual operating cost.

Built-in dryers are not typically associated with energy-efficient washing machines.

Energy-efficient dishwashers are designed to use less water while still providing effective dishwashing results.

Variable speed compressors allow air conditioners to adjust their cooling output based on the demand, leading to improved energy efficiency.

Energy-efficient lighting fixtures, such as LED bulbs, consume less energy while providing the same or better light output compared to traditional incandescent bulbs.

Built-in DVD players are not directly related to energy efficiency in TVs.

Energy-efficient computers are designed to consume less energy while still providing adequate performance for various tasks.

Power-saving mode is a common feature in smartphones that reduces energy consumption by limiting background activities and optimizing performance.

Energy-efficient chargers are designed to minimize energy waste during the charging process.

Built-in water softeners are not typically associated with energy-efficient water heaters.

Energy-efficient ceiling fans consume less energy while still providing effective air circulation and cooling.

Convection cooking uses a fan to circulate hot air, resulting in more efficient and even cooking.
