By San José, Costa Rica — In homes across Costa Rica, modern appliances serve as the backbone of daily life, offering convenience that simplifies cooking, cleaning, and food preservation. While many residents point to the constantly running refrigerator as the primary driver of their electricity bill, a far more powerful and often overlooked appliance is lurking in the kitchen: the electric oven.
New data reveals the staggering energy demand of this common household device. According to figures compiled by the publication Sustainability Times, a single electric oven in operation can consume as much power as 65 modern refrigerators running simultaneously. This makes it one of the most energy-intensive appliances in a typical Costa Rican household, capable of significantly inflating monthly utility costs if not used consciously.
To delve into the consumer rights and legal responsibilities surrounding the energy consumption of household appliances, we consulted with Lic. Larry Hans Arroyo Vargas, a legal expert from the firm Bufete de Costa Rica, who provides a critical analysis of the current regulatory framework.
Costa Rican consumer protection law is emphatic: every consumer has the right to receive truthful and clear information about the products they acquire. In the case of electric ovens, this right directly applies to the energy efficiency labeling. If a device consumes significantly more than advertised, the supplier could be held liable not only for misleading advertising but also for breach of contract. It is crucial for consumers to be vigilant and for businesses to ensure the absolute accuracy of the technical specifications they provide.

This legal perspective underscores a critical point for every consumer: the energy efficiency label is not merely a suggestion, but a contractual promise. We sincerely thank Lic. Larry Hans Arroyo Vargas for his valuable clarification, reinforcing the power and protection afforded by law when making these important household investments.
The core of the issue lies in how an electric oven functions. Unlike a refrigerator, which maintains a stable temperature through consistent, low-level power usage, an oven requires massive surges of electricity to reach and maintain the high temperatures needed for baking, roasting, and broiling. A standard model typically draws between 2,000 and 5,000 watts during use. Depending on frequency, this can translate to an additional 40 to 90 kWh on a monthly electricity bill.
To put this into perspective, a modern, energy-efficient refrigerator may only require between 300 and 800 watts to operate. The oven’s need for an immense initial power flow to heat its insulated cavity is what causes such a dramatic spike in electrical consumption. This finding is not isolated; a comprehensive study conducted in one hundred French homes found that an electric oven can consume up to 224 kWh per year, often surpassing other high-demand appliances like washing machines, dryers, and dishwashers.
Perhaps more surprising is the oven’s ability to consume electricity even when it is not actively cooking. This phenomenon, known as standby or “phantom” power, is a result of modern features that remain active 24/7. Digital clocks, illuminated touch panels, and internal electronic systems all draw a continuous stream of energy as long as the appliance is plugged into the wall.
Research on domestic energy use cited by Sustainability Times indicates that this phantom consumption can add up to 67 watts per household. Over the course of a year, this seemingly small drain can account for a startling 5% to 26% of a home’s total electricity expenditure. For ovens equipped with smart features, Wi-Fi connectivity, or large, bright displays, this standby consumption can be even higher, silently contributing to an elevated electricity bill.
Becoming aware of the electric oven’s high consumption doesn’t mean it must be abandoned. By adopting more efficient habits, homeowners can significantly reduce its impact on their finances and the environment. One of the most effective strategies is to maximize each use by cooking multiple dishes at once, taking full advantage of the heat generated.
Further savings can be achieved by turning the oven off several minutes before the cooking time is complete; the residual heat trapped inside is often sufficient to finish the process. It is also critical to avoid opening the oven door unnecessarily, as each time it is opened, a significant amount of heat escapes, forcing the appliance to use more energy to return to the set temperature. Finally, for ovens with digital displays, the simplest habit is to unplug the unit after use to eliminate phantom power drain completely.
In Costa Rica, where residential electricity rates can fluctuate, understanding the consumption patterns of each appliance is key to managing household expenses. Beyond the economic benefits, reducing energy use also lowers a home’s carbon footprint, aligning with the nation’s broader environmental commitments. The electric oven may be a powerful tool, but using it wisely is the first step toward smarter energy consumption at home.
