Advantage:

Fossil fuels play a very important role because we can use beauty products (to produce water and carbon) to generate energy. The usage that used that is very well in the history. Coal used to use for quchen metal. Semi-solid hydrocarbons leaked to the ground were also used as fuel in the era, but most of these materials were used as waterproofing and embalming agents. Commercial commercial oil production, largely replacing animal oils (such as fish oil) as fuel for oil lamps, dates back to the 19th century.

At the same time, natural gas or coal gas was also used extensively. The invention of internal combustion engines and the installation of them in cars and trucks has increased the demand for gasoline and diesel, both of which are distillates from fossil fuels. Other forms of transport such as rail and air also require the use of fossil fuels. Other sources of fossil fuel consumption include power plants and petrochemicals. Tar is the product left after oil extraction, also used as pavement material.

Disadvantages:

Under the principle of supply - demand, when the supply of hydrocarbons decrease, the price will increase. Higher prices, however, will increase the demand for renewable energy supplies, where previously unprocessed sources of supply will become valuable for commercial exploitation. Artificial gas and renewable energy sources are currently very expensive in terms of production and processing technologies compared to conventional oil supplies, but can become economically valuable in the near future.
