There is a single sun in our own solar system, but not in the universe. There are trillions upon trillions of suns (or stars) in the universe.
When we talk about the world, we mean the earth we live on. This world is a small planet revolving around the sun, one of many billions of other suns, or stars, in the universe. So, the world is very, very small compared to the universe.
Energy can be obtained by converting hydrogen into heavier elements (nuclear fusion). Suns usually have lots of hydrogen, which was available from the early stages of the Universe.
Around 1.15 billion suns could fit inside VV Cephei, which is one of the largest known stars in the universe. Its diameter is estimated to be about 1,650 times larger than the Sun's.
Our solar system is only a tiny fraction of the universe. Many suns exist out there somewhere, but we might not know their exact location.
