One aspect that we usually overlook when cooking is about the power of ovens and the amount of electricity they consume. Let's take an in-depth look and discover some practical tips on how to save energy when using your oven.
What power does an oven use?
A normal oven usually uses between 900 and 3,500 watts of power (W), although this depends significantly on the functions we use to cook and the type of oven. For example, a domestic electric oven has an average power of 1500 watts (W) in normal use.
Therefore, if you use your oven for 1 hour to bake a cake, you would be consuming 1500 watts per hour, i.e., 1.5 kW/h.
10 Tips for saving energy when using your oven
1. Cook several dishes at once
Without saturating it, one good way to save energy when using your oven is to cook several dishes at the same time. Most home ovens have enough space to cook several dishes simultaneously. This way, you get two for the price of one in your kitchen saving money, energy and time.
2. Don't open the door while cooking
It is true that often you might have to open the door to check that your dish is turning out as planned. However, by reducing the number of times you open the oven door when cooking, you can avoid a loss of heat, achieving a more efficient and sustainable use.
3. Harness residual heat
Once you have finished using the oven, it will still retain a lot of heat that you can continue to use to heat other foods. Instead of using your microwave, use the residual heat in your oven to heat other dishes and save energy.
4. Turn off the oven 5 minutes before
Another way to harness the residual heat is to turn the oven off 5 minutes before finishing cooking your dish. The residual heat will be enough to finish the dish without affecting its quality and you could save, using this simple trick, more than €3 per month.
5. Cook food in smaller pieces
The same amount of a food, baked in smaller portions, requires a shorter cooking time. A very simple way of saving time and money when using your oven, with the same exquisite results. Furthermore, this makes it much easier to serve meals if you have already prepared the portion sizes.
6. Keep your oven well maintained
Cleaning and maintaining your oven are two other factors that greatly enhance the energy savings offered by this appliance. Over time, the door might not close properly or either the thermostat or fan might fail.
Furthermore, significant amounts of accumulated dirt can result in the heating of the resistor or the gas burners not being distributed homogeneously within the oven.
When taking care with cleaning and performing small checks on the most important points of your oven, you can extend its useful life and help consume less energy.
7. Use suitable baking containers
Your choice of container is essential to get the most out of each kW/h consumed by your oven. For example, ceramic or glass containers retain the temperature very well and can help to avoid having to heat the oven too much. Another example are metal containers indicated for baking, which heat up quickly and are perfect for dishes that require temperature in short periods of time.
8. Pre-cook vegetables
Boiling vegetables before baking them is one very interesting way of saving energy. This reduces baking times, thus saving energy and the results are amazing.
9. Choose ovens with a high energy rating
Although it is true that they require a greater initial investment, ovens with A or B ratings provide energy savings and offer maximum performance in the long run.
