The ministry of energy is a big group of grown-ups in Iran whose job is to make sure that people have electricity, water, and fuel. They do this by figuring out how much of these things we need and where we can get them from. They work with other big groups of grown-ups to make sure that we have enough energy to make things work, like turning on the lights in our homes or making the cars go. Sometimes they have to make hard decisions about how much of these things we can use, because they want to make sure that we don't run out of them. Basically, the ministry of energy helps to keep our country running smoothly.
