Kerosine is a popular fuel for lanterns. It also can be used in small heaters. From this same middle level comes diesel fuel and heating oil. Diesel fuel operates trucks and tractors, ships and trains. Many homes use fuel oil rather than gas or electricity to run the furnace.
Many power companies create electricity by boiling water and having the steam turn a motor.
This motor turns a generator, which makes the electricity. Just think, the fuel used to create electricity took several million years to make, and it's used up in just seconds. That means that you should turn lights and TVs off when you're not using them. Here in the lower part of the tower, the crude oil vapor condenses, and we get lubricating oil. When Mom or Dad says that the car is a quart low, they mean that the car needs more oil from lubrication or grease.
