💭 Warm-Up Question
How do you usually use energy at home during the day?
📖 Short Reading
Energy use at home is important for many daily activities. We need electricity for lights, cooking, and heating or cooling rooms. Using too much energy can increase bills and waste natural resources like coal, gas, or oil. Many homes also use energy for water heating and electronic devices. Turning off lights when not needed saves energy. Using energy-efficient bulbs and appliances also helps reduce use. Some families set timers on heating or cooling systems to avoid wasting energy. Insulating windows and doors keeps heat in during winter and cool air in during summer. Solar panels can help produce clean energy but need a good sunny place. Simple actions from everyone at home can make a big difference in reducing energy use and protecting the environment.
