Natural Gas as Fuel
The same natural gas that many of us use for cooking and heating can also be used as an engine fuel.
It is far less polluting than gasoline. And it is cheaper than gasoline.
Around 85% of the natural gas we use comes from the US and Canada, whereas over 50% of our gasoline comes from OPEC and Persian Gulf countries.
Increased use of natural gas would greatly reduce our dependency on foreign oil.
Natural gas is not regularly used by individual car owners because it is not readily available.

Natrual Gas

Resource
It is used mostly by large companies and government agencies who can afford to build their own natural gas fueling stations.
Many city and airport bus systems, taxi cab companies and private companies with fleets of cars use natural gas powered vehicles. Several million are in use around the world.
Current gas stations could make natural gas pumps available to you.
Recent Update:
The NewWave is happening!
Honda is now selling a passenger vehicle that runs on natural gas. It's called the Civic GX. You can find a dealer who sells the car by going to the Honda Civic GX website.

Equally important is the fact that many more fueling stations that pump natural gas are open to the public. At the time of this update natural gas prices are much cheaper than gasoline.
Ethanol Fuel
Ethanol is a liquid fuel made from vegetable type sources instead of from oil.
Sources for ethanol include corn, wheat, barley, trees and grasses, etc.

Green Power
Ethanol is less polluting than gasoline.
Because ethanol is created from renewable resources, wider use of ethanol would greatly reduce our dependency on foreign oil.
Ethanol is most commonly mixed with regular gasoline and many vehicles are made to run on a fuel mixture known as E85 which is 85% ethanol and 15% gasoline.
Major auto manufacturers such as Ford, Chrysler, Nissan, Mercedes-Benz and GM make several vehicles which use ethanol. They are sometimes known as Flexible Fuel or "flex fuel" vehicles (FFV).
Ethanol is now becoming more and more available at fueling stations across the US.
Ethanol could easily be made available to consumers at all currently existing gas stations.
Biodiesel is a fuel made from renewable resources such as soybeans and mixed with regular diesel fuel for use in diesel engines.
The unique case of Algae
Fuel produced from algae is very different from most biomass based alternative fuels.
Most of these fuels, such as ethanol, convert biological matter into an alcohol. Algae sourced production is based on algae, a living organism, feeding on a solution created by water, carbon dioxide and sunlight and biologically converting it into an oily substance.
The resultant oil can be eventually processed in the vast oil/petroleum gas infrastructure that currently exists to process petroleum based oils.
One of its main advantages is that the production of this alternative fuel does not rob the overall community of food and feedstock resources, such as corn.
The companies involved in algae based fuel estimate they can produce tens of millions of gallons of usable fuel by 2015.
