* Compressed natural gas (CNG) - natural gas.
* Electricity - generated by coal, water, wind, solar or geothermal.
* Hydrogen - a very flammable gas...

Natural gas unfortunately is a non renewable resource, and is used as a feed stock for a lot of the alt fuels at the moment...
Fortunately, there is a lot of natural gas available which makes these other technologies viable and cheap...
The supply of NG is naturally stable and cheap, too, which makes it a viable option in the short term until it too becomes a rarer option...
