Alternative fuel is obtained from the updatedsources of energy. For example, as an alternative to oil, fossil fuel derivatives (liquefied petroleum gas or natural gas) are widely used in many countries. Also, as fuel for cars, you can use hydrogen or electricity, obtained from both fossil and renewable sources of energy. At the same time, the automotive industry that uses these fuels is only in its infancy.

Alternative fuel becomespriority in connection with the constantly deteriorating state of the environment, as well as the impossibility of fully meeting the ever-increasing demands of motorists for world production of oil. One example of a fuel that opposes oil and gas products is biofuel. Unlike hydrogen and electricity, its use for transport does not require significant changes in modern infrastructure, engines and equipment. Thanks to this fact, the gradual conversion of the fleet into biofuel becomes a reality.

Today, researchers alternative fuel is grouped into eight types. All of the types listed below have the potential to replace gasoline and diesel in the future.

For example, methanol (wood alcohol)used in cars. Its main advantage is environmentally beneficial indicators. Countries such as the United States and China have recently been actively implementing programs for the use of methanol as a fuel.

Liquid fuels used asan alternative to the existing one, is represented by ethanol, which is made on the basis of alcohol by distillation and fermentation of some crops (barley, corn and wheat). To improve the quality of environmental performance and increase the octane number, it can be mixed with gasoline.

Gas fuel is now widely used by the population of most countries. So, natural gas is supplied to enterprises, to apartment houses by municipal services.

But mixing hydrogen with natural gas, they receive alternative fuel for cars equipped with internal combustion engines.

Electricity can be used onlyelectric vehicles with battery power. Energy is stored in batteries that need to be recharged by connecting the vehicle to a standard type electrical source.

Biodiesel fuel is made on the basis of animal fats and vegetable oils.

Liquefied petroleum gas, called propane,is obtained by processing crude oil and natural gas. This type of alternative fuel is widely used in human life. For example, for heating and cooking. Today, propane is a popular fuel for motor vehicles.

And, finally, the last kind of alternative fuel- P-series, which is a collection of ethanol, methyltetrahydrofuran, liquefied natural gas and co-solvent, which is obtained from biomass. Such fuel has a high octane number and therefore can be used even by cars with multi-fuel engines.

A list of alternative fuels would beincomplete, if not to mention such innovations as the manufacture of a heat source and additional energy from solid waste. Already in many countries, corresponding factories have been built, whose "finished products" are entitled to solve two problems simultaneously. First, to prevent environmental pollution due to the constantly increasing amounts of debris. Secondly, a positive solution to environmental issues.
