Electric vehicles use grid power that can come from various sources, but now that is primarily coal then oil then other.
Hydrogen fuel cell technology is proven to work, but at a million dollars per car plus a very high rate for hydrogen to operate that is not viable for about 50 years even if the automakers got full on board with it.
The best chance is the water separator to hydrogen+oxygen then run the car on that, which returns to water after combustion. It uses existing Internal Combustion Engine technology, requires moderate alteration of existing vehicles and the source of fuel is abundant. But again this technology is a ways out except for fringe scientists that have to work privately, funding their own research and hoping that they survive the Big Three automakers and their death squads.
Remember that big oil and big auto industries are practically one and the same. What is good for the people is bad for the shareholders by nature.
bio-diesel fuels are a good alternative to fossil fuel.
used cooking oil from fry vats is an alternative to fossil fuel, but the engines that use those being ICE diesel engines still require regular or bio-diesel to start and end the trip

A lot, you may consider Water. You may see the same impossible, but it is otherwise. There is a Technology now that separates the two Chemical Component of Water - Hydrogen and Oxygen. There is this gadget attached to the machine of the vehicle that automatically separates the Hydrogen componet of the water and that is the one being utilize as fuel, renewable isn't it ?
There is also vehicles run by Electricity by and through Solar and Wind Energy.
There is this CNG or the so - called " Compressed Natural Gas ".
Our mission therefore is to help propagate, promote and demand to our respective governments the use, propagation, promotion and most importantly the mandatory law for the implementation of the renewable energy and the banning or prohibition of using the fossil fuel, as source of fuel not only for our vehicles but to all appliances, pieces of equipment, tools, gadget, machines and other things that need fuel to be operated.
Long live the utilization of renewable sources of Energy.

I suspect in the future that we'll be driving cars that use synthetic fuels, either hydrogen or synthetic hydrocarbons (produce them using nuclear power).
Electricity can be used but our battery technology isn't really up to it although hybrids can give the internal combustion engine a significant improvement in fuel economy and power.
Biofuels are a stupid idea that we shouldn't be wasting any money on, instead we should be using the corn to feed people (or turning the farmland back to nature).

Cars that run on fossil fuels - gasoline, diesel, hybrids (because their only fuel source is gasoline - no plug-ins available!), LPG, CNG, and even flex-fuel vehicles (E85 - still 15% gasoline, and VERY few E85 capable cars are ever even fueled with it because of the sparce fueling network)
Then you have electric vehicles (few, but they exist, usually battery electrics). The problem is how do you charge the battery? Perhaps your local power source is biomass (garbage, cow poo/methane), hydroelectric, wind, tidal, solar, or even nuclear, so then you'd be fossil-fuel free. However, many power plants still rely on coal, oil, and CNG for their fuel... Hydrogen vehicles are really just electric vehicles, just that their battery is the hydrogen fuel cell. There again, through what process did you crack the hydrogen - breaking hydrocarbons from fossil fuels, or using electricity/electrolysis (same problem as the battery electrics)...
At least diesel engine vehicles, with little to no modifications to the engine/fuel system, can run on biodiesel (diesel created from waste vegetable oil, like from restaurants), or with some conversions to run on straight waste vegetable oil.
In the early days of automobiles, steam-powered cars were common. I guess you could use wood/charcoal as fuel, to stay away from the fossil fuel coal.
There are also some concept vehicles about using advanced flywheel designs. Similarily, one could look into a wind-up/spring propelled design (like seen on toy cars).
I've also heard of concept compressed-air propelled cars, too.
of course, there's nothing stopping you from hitching up a team of horses or oxen (or strong men!) to pull your existing car, either! but then the car isn't running on its own.

Biodiesel, electricity from the power grid, and eventually maybe hydrogen. Solar energy can provide some of the power for a car as well. See the links below for further details.

I guess you could make a Hydrogen car, or a Solar powered car.
I don't think it will be possible to create the sorts of cars we have now. They will be slower and won't be able to go as far. You could probably say goodbye to your Hummer or your Ferrari F-50, or even your Toyota Camry. They'll probably all look like Smart Cars.

Hydrogen cell technology seems to offer the best result with 0 (Yes zero) emissions

We have the biofuel, which came from the organic materials like animal dung, waste etc.
