Energy isn't created or destroyed,it's transferred, so it's transferred from the center of the Sun through the atmospheres to us in many forms, warmth and light via the plants and via the food that we eat.

Ancient man was right to worry whether the Sun would rise again, it's been burning for 5 billion years, but it's now used up half its hydrogen fuel resisting gravity, one morning the Sun will rise on a last perfect day on Earth, for many years we have no idea when the end would come, but now we can predict the Sun's fate and our own, we have learnt it not by studying the Sun, but by observing all the other stars in the sky, the breakthrough came when American astronomer Henry N and the Dane tried to create a pattern that made sense of all the stars in the night sky.
