Some ovens are heated by burning gas. Water is a byproduct of the burning of gas, and this creates a humid environment inside the oven. While this reduces the need to cover foods to prevent drying, it also prevents drying when drying is desired. Gas ovens generally provide poor support for broiling. Gas fuel is cheaper than electricity in some areas, and gas ovens often come with the generally desirable gas cooktops.
