According to Wikipedia, fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. A fuel contains energy, mostly heat, which can be released and then manipulated. Most fuels used by humans undergo combustion, a redox reaction in which a combustible substance releases energy after it ignites and reacts with the oxygen in the air. Other processes used to convert fuel into energy include various other exothermic chemical reactions and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons are by far the most common source of fuel used by humans, but many other substances, such as radioactive metals, ,are currently used as well.
In economics, fuel is one of the inelastic commodity goods because the world needs so much fuel every day to run and will factually need to pay whatever it costs, or it will cease to run. Yet, once the price for the fuel increase, the consumers were still consume the fuel as the fuel played such an important commodity together with development in economics. Fuel have a lot of functions that would give us plenty of benefit such as, we are using fuel to produce energy and generate the power especially in the industrial sectors, using for transportation, construction, and so on.
When a war breaks out in Country A, which is the main producer for fuel in the world, it causes fuel supply disruptions in the world. Essentially one of the hottest news on global market is oil price fluctuation because the consumer will give their responsiveness immediately as the price of fuel keep increasing day by day. It is because crash in oil market can disrupt stability of any industry. The world’s current energy systems have greatly depended on certain fuel rich regions. For example, two thirds
