For cooking , use your resources efficiently : first kitchen with a microwave , then pressure cooker with oven last.
Make sure that the bottom of the containers is slightly above the cooking area so that the flame does not exceed : fully leverage the heat of the kitchen.
In electric cookers and cookware used the rest of the household with a thick diffuser : achieve a uniform temperature throughout the container.
Whenever you can use pressure cookers Super fast (not just steam loss during cooking) : consume less energy and save much time.
Cover the pans during cooking : consume less energy.
Take advantage of waste heat from electric cookers (except induction ) turning them off about five minutes before end of cooking .
Use the microwave instead of the oven , saves between 60 and 70 % of energy and a considerable saving of time.
If you buy an electric oven try to be class A.
Do not open the oven only to not get bored . Every time you open it you’re losing at least 20 % of the energy stored inside.
Try to maximize the capacity of the oven and , if possible at once, the more food .
Generally it is not necessary to preheat the oven for cooking over an hour.
Turn off the oven just before the end of cooking : the residual heat will be enough to finish cooking.
Convection ovens promote uniform distribution of heat, saving time and , therefore, less energy .
