　　     Electrical energy comes from the sun in a roundabout way, e. g. it　　 can come from the power of water falling down a mountain.

　　     Energy which we use to drive car engines comes from petrol, which　　 also was made with the aid of the sun in a roundabout way. Plants and　　 animals ate the plants died millions of years ago. It was these parts　　 that made petroleum, from which petrol and oil are now used by people.
