Convection cooking is generally more energy efficient than using top and bottom heat. This is because convection ovens use a fan to circulate hot air around the food, which allows for more even and faster cooking. This means that food can be cooked at a lower temperature for a shorter amount of time, ultimately saving energy. Additionally, convection ovens often have better insulation and more precise temperature control, further contributing to their energy efficiency. **
