How many alternative fuels are there?
Alternative fuels are more popular than ever. It is widely known the fact that alternative fuels generally produce fewer vehicle emissions that contribute to smog, air pollution and global warming. There are 8 top alternative fuels: ethanol, natural gas, electricity, hydrogen, propane, biodiesel, methanol and p- series fuels. The excellent news is that alternative fuels can help any nation become more energy independent. This is excellent. Needless to say, most alternative fuels are not derived from finite fossil-fuel resources.
