Always use the lid. This advice is especially important for preparations that need a longer cooking. Using the lid the heat is distributed more evenly and more effectively, saving us up to 25% of energy.
Check out the flame. It must be blue in color, which indicates a good combustion of gas. A yellow flame, on the other hand, signals us that the combustion process is not complete.
Keep the burners from the stove clean. Clean and good burners are important to avoid further heat loss.
Once boiled, it lowers the flame. Cook your food at the right temperature. Leaving the flame high, in addition to making us consume more gas, makes us run the risk of burning our dishes.

Take advantage of the residual heat. Once the stove is turned off, pots and pans continue to be so hot that we can afford a few more minutes of cooking.
Use the pressure cooker. To some it is even scary, but it is a very useful and economical tool, which allows us to save up to 50% of energy.
It thaws before cooking. Defrost food the night before saves us energy. A frozen food takes longer to cook.
Organize everything before cooking. Pots and pans don’t take long to heat up, avoid consuming energy while looking for what you need to prepare the dishes.
Avoid opening the oven continuously. Learn to use a timer to have precise stitms and not need to continuously open the oven to check them.

Learning to consume less gas does not only benefit the wallet, but it is also useful to protect the environment.
