How do we obtain energy from fossil fuels?

The process of obtaining energy from fossil fuels is primarily achieved through combustion, which involves burning them. When fossil fuels such as coal, oil, or natural gas are burned, a chemical reaction occurs that releases energy in the form of heat. This heat can then be used to produce steam that drives turbines in power plants, generating electricity, or it can be used directly for heating.

Burning fossil fuels releases carbon dioxide and other gases, contributing to atmospheric pollution and climate change. This combustion releases a significant amount of energy because fossil fuels are made up of hydrocarbons, which contain stored chemical energy from ancient biological materials.

The other methods mentioned, such as dissolving fossil fuels in water, storing them under pressure, or converting them directly into electricity without combustion, do not effectively capture the energy stored in fossil fuels. These alternatives do not involve the conversion of the chemical energy into usable energy in the way that burning does. Thus, the method of burning is the clear and correct answer when discussing how energy is obtained from fossil fuels.
