Did you know that most of the energy used by an oven is during the preheating time and after the oven door has been opened? And on hot days, the longer the oven door is open, the hotter your kitchen gets, since that hot air is escaping into your kitchen.
Whenever you are baking in the oven, try and only open the oven door for the shortest period possible. This means have the baking dish sitting on the stovetop so you can immediately place it in the oven, rather than opening the oven door, walkin across the kitchen to another counter, walking back with the dish, and then closing the oven door.
When you only open the oven door for the shortest period of time possible, you will save money on your electricity bill, as well as save money on your air conditioning because it won’t have to work as hard to get the house temperature down because of the oven being used.
