Energy is one of the most important resources for mankind and its sustainable development. Today,
the energy crisis becomes one of the global issues confronting us. Fuels are of great importance because
they can be burned to produce significant amounts of energy. Many aspects of everyday life rely on fuels,
in particular the transport of goods and people. Main energy resources come from fossil fuels such as
petrol oil, coal and natural gas. Fossil fuel contributes 80% of the world’s energy needs. Most industries
use diesel machines for the production process. In the transportation sector, private vehicles, buses,
trucks, and ships also consume significant amounts of diesel and gasoline. This situation leads to a strong
dependence of everyday life on fossil fuels. However, the growth of the population is not covered by
domestic crude oil production [5-6].Fossil oils are fuels which come from ancient animals and microorganisms.
Fossil fuel formation requires millions of years. Thus, fossil oils belong to non-renewable
energy sources.
