How to be more efficient in the kitchen

When cooking, there are ways to achieve better results with less effort. If you apply these tips, you will save time, trouble and money, in addition to helping to preserve the environment. 

Eating may seem like a relatively innocuous activity, but in reality it is something we do several times every day, and which is of decisive importance in various fields, from the smallest to the largest:

  • Our physical and mental health.
  • Our economy.
  • Our planet.

Becoming efficient in the kitchen is therefore a challenge with a triple benefit.


  1. Think about what you buy

The challenge begins with the first port of call: the supermarket or the shop where you stock up on food. This is where your carbon footprint comes into play, which is the amount of polluting gases you emit into the atmosphere with each activity.

Every purchase decision is allocated a certain number of points, contributing to your carbon footprint. Where the food comes from or how it has been processed are very important factors.

For example: fresh fish being transported to the supermarket adds 2 points, while driving 15 km by car adds 4 points. So, buying fish from a local shop will keep the score at 2, while driving to a big supermarket to get it will raise it to 6 (2 + 4).

Following this logic, you can judge how to organise yourself. You should shop as close to home as possible, but it is also important for the products we buy to have travelled only a short distance. The further away a food comes from, the greater its carbon footprint and therefore the worse it will be for the environment.

We can apply the proximity principle: try to avoid food produced more than 100 km away. There are now many restaurants that are convinced about the gastronomic sustainability of zero-mile food.

"Shop as close to home as possible and choose locally produced food. "

2. Saving energy when cooking

The next step of the challenge comes when you get home with your shopping bags. It's time to get cooking, and of course it is important to have efficient appliances, something you can guarantee by understanding your energy label in depth

  1. Once you have efficient appliances, you should follow these 4 top tips
  2. Microwaves consume the least amount of energy and, in addition, cook the fastest, consuming approximately 60% less energy than a normal oven. Other than microwaves, the most efficient ovens are convection ones
  3. Every time you open the oven, around 20% of the heat escapes, so it is advisable to open it as little as possible. It is also a good idea to cook several dishes at the same time or use the residual heat (the heat that remains after you turn the oven off) to heat up other things.
  4. Gas hobs are the most efficient , followed by the induction and ceramic. Gas is more efficient at producing heat than electricity. A natural gas hob emits 200 grammes of CO2 for every kWh, while a ceramic hob emits 450 grams and an induction hob emits 360 grams.
  5. It is important to look after your appliances and your electrical and gas installations. To do this, it is essential to have a good maintenance and breakdown service.

3. Batch cooking and real food: sustainability with homemade food

The challenge continues with planning your weekly menus. The goal is to cook as few days a week as possible. This way, you maximise the efficient use of energy and minimise the time/effort involved in cooking.

Here, the philosophy of batch cooking can help a lot, by using electrical appliances as little as possible, as can focusing on real food and avoiding ultra-processed foods.

By cooking in batches and planning what you are going to eat in the coming days, you reduce the amount of energy you use. By avoiding ultra-processed foods, we escape a production chain with multiple steps that increase the emission of harmful gases. It is about opting for natural, locally produced foods, helping us reduce our carbon footprint by more than 25%.

"To be efficient, avoid ultra-processed foods: you will achieve better results in terms of your health and your energy use."

4.    Fight waste

When food ends its journey and ends up in the bin, the sad result is that a large part of the polluting gases released to produce it have been in vain. In 2018 alone, Spaniards threw away 1.34 billion kilos/litres of food and drink in good condition.

You should therefore strive to:

  • Buy only what you need.
  • Opt for foods with no packaging or easily recyclable packaging
  • Be creative with leftovers, don't throw away food that can still be eaten.

And we are not just talking about food. We must also take energy into account.

Energy waste is increasing and we have it in our power to enjoy all the comforts without consuming too much.

With Unica by Endesa, you always pay the same fee, or even a lower fee.


We have an efficiency Challenge Plan prepared for you:

  1. You only need to be a customer of Única by Endesa.
  2. We will send you personalised challenges by email that encourage you to reduce your energy consumption:
  • If you consume less, you pass the challenge and that saving will be reflected in your next instalment (keep in mind that the electricity challenges are quarterly, while the gas challenges are annual). We will help you pass the challenges with efficiency tips and we will tell you how you are doing.
  • If you do not pass the challenge, you will still pay the same, without any unpleasant surprises or changes in your charge.

What are you waiting for? Start saving and look after the planet!

"Spaniards waste more than 1.3 billion kilos/litres of perfectly good food each year, a sign of inefficiency."
