Coal at the current rates of consumption. Crude oil has hundreds of years of availability also, but as it becomes less plentiful, we have to reach further for it or use less workable forms of the raw material.
Coal will most likely last the longest. It is being used less often then in the past. It is also the most abundant fossil fuel
As long as a fossil. Over billions of years.
There is not to much fossil fuel left of the whloe world of have fossil fuel. we need to work lees time of it to last more time .
this fossil fuel provides about 40% of the worlds energy
Carbs are the chief fuel. they last the longest
If you are using bio fuel you are not using fossil fuel. Crude oil is a fossil fuel
Until the alien comes and destroy us, fossil fuel will last forever
We can't because fossil. Fuels are made from non renewable energy which wil eventually will be finshed
natural gas
Oil. And lots of it. Not enough to last forever, but plenty for now.
one fossil fuel is Peat another one is lignite also bituminous coal anthcite trace fossils and last but not least droopings
The stars that have the longest lifetimes are the smaller, cooler stars - red dwarfs. They are just about massive enough to sustain nuclear fusion of hydrogen fuel, but consume fuel at a very low rate. They could last for hundreds of billions of years before they exhaust their fuel.
