Propulsion alternativeLa propulsion alternative des véhicules (voitures, camions, navires) consiste en deux catégories : les moteurs à combustion et explosion alimentés par des carburants alternatifs tels les biocarburants, biodiesels, biogaz, diesters, huiles végétales carburant ; les systèmes alimentés par d'autres sources, dont les moteurs Stirling, piles à combustible, batteries d'accumulateurs, moteurs à air comprimé, panneaux solaires ou éoliennes.
Ethanol fuel in BrazilBrazil is the world's second largest producer of ethanol fuel. Brazil and the United States have led the industrial production of ethanol fuel for several years, together accounting for 85 percent of the world's production in 2017. Brazil produced 26.72 billion liters (7.06 billion U.S. liquid gallons), representing 26.1 percent of the world's total ethanol used as fuel in 2017. Between 2006 and 2008, Brazil was considered to have the world's first "sustainable" biofuels economy and the biofuel industry leader, a policy model for other countries; and its sugarcane ethanol "the most successful alternative fuel to date.
Alternative fuel vehicleAn alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels (petrol or petrodiesel). The term also refers to any technology (e.g. electric cars, hybrid electric vehicles, solar-powered vehicles) powering an engine that does not solely involve petroleum. Because of a combination of factors, such as environmental concerns, high oil-prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world.
Véhicule polycarburantUn véhicule polycarburant ou VCM est un véhicule dont le moteur peut utiliser deux ou trois types de carburants. On dit aussi véhicule bi-combustible, tri-combustible ou multi-carburant. L'acronyme « VCM » (pour « véhicule à carburant modulable ») est la dénomination officielle française. Le terme anglophone « Flex fuel », couramment utilisé pour désigner tout type de véhicule polycarburant, désigne en français une technique particulière de moteur polycarburant.
