Gobs companies sell conversion kits allowing petrol and diesel powered cars to bound on alternative fuel. Biodiesel, for instance, can be created from the surplus of used vegetable oil from fast food restaurants.Tax Credits
The United States Internal Revenue Service allows tax credits for owners of vehicles with alternative fuel conversion kits.
Alternative fuels all have reduced carbon emissions compared to using gas or diesel for fuel.
Dependence on Oil
Using alternative fuels reduces dependence on imported oil and the need for domestic drilling.
Fuel Economy
Most alternative fuels provide better fuel economy, thus increasing fuel mileage.
Availability
Many alternative fuels are readily available. People using these converters can switch back and forth between gas and the alternative fuel. Types of alternative fuels include biodiesel (vegetable oil-based), biogas (methane and carbon dioxide), ethanol (corn-based), hydrogen, methanol, natural gas and propane. Most cars and personal use trucks can be converted to alternative fuels without having to replace the engine.
