Solar is not practical. Geothermal is not possible for a car. Wind is not practical either. Tidal energy is not possible. Any internal combustion engine will run on propane / methane / natural gas (they are all basically the same thing) with very little modification. The exhaust is a little better than 98% clean. Any internal combustion engine can be modified to burn hydrogen, with warm water vapor as the only exhaust. Any diesel engine can burn cooking oils. Much lower exhaust emissions. Electric cars are possible and do exist, but the costs are high and the maintenance is high. Fuel cell cars are here but are high maintenance and do not perform well in cold temperatures and refuse to operate in very cold temperatures (they freeze solid – water does that).

Any fuel source has to be portable. Look up LPG Liquefied Petroleum Gas and propane.

Wind energy possible. Geothermal and Tidal Energy not possible unless the vehicle is going to be underwater or in attached to the ground or stationary which means they would not be cars as defined because they would not move.
