We will have to run electric cars, which exist today. There is talk also of cars that run on compressed air. Hydrogen is another fuel source that will run cars if we can manufacture it cheaply enough, and store it safely in the cars.
Cars can be adapted to run on a wide range of renewable fuels by using diesel engine. The diesel engine is one of the most effective energy converters available to us today.
As of 2018, most cars run on fossil fuels such as gasoline or diesel; there is an increasing tendency for cars to run on stored electrical energy (batteries), but those cars are still in the minority.
Cars can run on Hydrogen gas, however the car's engine must be modified first.
Gasoline and ordinary diesel fuel are both fossil fuels, so almost all cars run only on fossil fuels.
They could make alternative fuels.
When fossil fuels run out we will have to do without cars (unless they run on an alternative,) cold houses, and we will be forced to use different things to start fires and eventually the human race will be fighting for whatever is left.
