Energy efficiency experts warn that frequently opening the oven door to check if food is ready is a habit that can increase the electricity bill. According to the article, each time the door is opened, part of the accumulated heat inside escapes into the kitchen, forcing the appliance to work again to recover the set temperature.
According to Carles Torrecilla, a professor at Esade cited by the Spanish newspaper El Español, each time the door is opened it can cause a loss of up to 20% of the accumulated energy inside the oven. This gesture, very common during meal preparation, ends up representing an energy waste when repeated frequently.
The article mentions that leaving the oven preheating for longer than necessary also represents additional consumption. Furthermore, experts draw attention to similar behaviors in other appliances, such as opening the refrigerator for too long or placing still hot food inside.
The main recommendation is to avoid constantly opening the oven during cooking, use the interior light to monitor food, and respect the times indicated in recipes. These are small behavioral changes that, combined with efficient use of other appliances, can help reduce energy consumption at home.
