Oil is typically extracted from underground reservoirs through drilling operations and can be refined into various products such as gasoline, diesel, and jet fuel. Oil is transported via pipelines, tankers, and other means.

Nuclear energy is another significant source of energy, generated by the process of nuclear fission. This involves splitting atoms, releasing a large amount of heat energy that can be used to generate electricity.

Natural Gas is a versatile fossil fuel that can be used for various purposes, including heating, cooking, and generating electricity. It is often transported through long pipelines and can be stored underground in depleted gas reservoirs.

Mining refers to the process of extracting valuable minerals or other geological materials from the Earth. While not directly an energy source itself, mined resources like uranium (used in nuclear power) and coal (a fossil fuel) are crucial
