Biodiesel: is a mix of diesel gas and vegetable oils. The pros of using this fuel are that it produces less carbon emissions and harmful particulates than standard gas. It is an increasingly easy choice for car buyers to make since there are many biodiesel-fueled models on offer. In terms of fuel availability, while biodiesel outlets may still show short supply nationally, drivers retain the choice of filling up with standard diesel gas.Finally, Biodiesel is more energy efficient in production than gas.
Ethanol:ethanol-fueled vehicles run on a mixture of gasoline and a propellant derived from grain. On the pro side, there are an increasing number of alternative fuel cars now being supplied for this market. The most popular ethanol fuel brand is E85. The name reflects the proportions of 85 percent ethanol to 15 percent gasoline used in the fuel. This makes it an emissions-friendly fuel. It also provides another potentially large and profitable market for arable farmers.
Hybrid Cars: Hybrid cars operate by using a combination of gasoline power and electric power. In addition to the gas tank they have an electric battery that stores energy during the speeding and slowing parts of a typical journey. The pros of this type of vehicle include the substantial saving in fuel costs through the engine's efficiency.
Hydrogen Cars: Hydrogen is a fuel that appears to have enormous possibilities. The pros begin with the fact it comes from water and is, therefore, a renewable fuel with inexhaustible supplies and benefits in fuel cost. The exhaust from a hydrogen-fueled car is totally environment-friendly. Hydrogen cars also give the driver excellent mileage compared to regular gasoline cars.
