Eating may seem to be a relatively harmless activity but in reality it is something that we do every day, various times a day and which has a decisive importance in various areas, from the smallest to the biggest:
- Our physical and mental health.
- Our economy.
- Our planet.
Let us discover how to save energy in the kitchen while taking care of ourselves and leading a more sustainable life.
1. Think about what you buy
The challenge begins and it does so from the first station along the journey: the supermarket or the shops at which food is purchased.
Here the most important thing is to take into account the carbon footprint, which is merely the amount of pollutant gases emitted into the atmosphere with each activity.
Each purchase decision leads to a rate, a number related with the amount of CO2 emitted into the atmosphere during its transportation.
For example: fresh fish reaches the supermarket with a rate of 2 and travelling 15 km by car represents a rate of 4.
Hence, if we wish to engage in efficient cooking, we see that buying fish next door, or in the neighbourhood, will maintain the rate of 2, while if we go by car to a shopping centre to buy it, the rate will rise to 6 (2+4). Look how easy it is to save energy when cooking, up to 66%.
Following this logic we can judge how to organise ourselves to cook more efficiently. We must travel as little as possible to shop, but it is also important that the product that we have purchased has travelled a short distance.
The further the origin of the food, the greater the carbon footprint and, therefore, the greater the damage to the environment.
We can apply a principle of proximity: attempt to avoid food produced over 100 km away. There are many restaurants that ask how to save energy in the kitchen and that are joining the gastronomical sustainability 0 km scheme.
