I learnt today at school that the fossil fuel oil supply will run out supposidly within the next hundred years, i this true?

Also i know about reusible fuel sources, but is there anyway of artificially creating fossil fuels on a low budget?

How long will it take to naturally reproduce oil... millions of years... billions... 3 years?

Fossil fuel is fuel made from petroleum which will definitely run out at some point. How soon depends on how much is actually down there and how fast we use it; two variables that are hard to estimate.
There is no way to make artificial fossil fuel, strictly speaking, because petroleum is formed from organic matter that has to sit deep underground for millions of years. There are ways to make fuels which can be used to replace fossil fuels, like ethanol from corn for example. Scientists are also working on things like genetically engineered bacteria which can make petroleum-like products from agricultural waste. Whether any of these things actually can be used as a viable alternative to fossil fuel depends on their cost and efficiency.
Incidentally, none of these alternatives are 'reusable'. Once you burn fuel, it is effectively gone. They are, however, 'renewable' which just means that the source of the fuel (i.e. corn) can be replaced relatively easily.

On how soon oil will "run out" (i.e. become so expensive to find and extract that it is no longer commerically viable), it's well worth reading Prof. Steven Dutch's short article "So What's With the Price of Oil?".  The short answer is, yes, it's going to happen well within the next hundred years. http://www.uwgb.edu/dutchs/PSEUDOSC/PriceofOil.HTM

This just showed up in my RSS reader today:

It shows the size of the recent Gulf of Mexico oil spill compared to other spills and to the size of world oil consumption. It estimates a rather bleak 29 years worth of proven reserves.

I was at a lecture at the Linnean Society the other week and was informed that it is very likely peak oil has either happened or will happen in the next couple of years, corroborated by the US Army report for the Joint Forces Command
(http://www.guardian.co.uk/business/2010 … ion-supply), article here: http://www.karavans.com/GetTRDoc.pdf.

As the US Military is probably the largest single consumer of oil on the planet, this makes interesting reading, as it does not tally with what the Energy Information Administration are saying. I'm not saying this is conclusive but it's certainly something to think about, what with politicians banging on about the necessity for economic growth (which, ultimately, can't happen without oil...)...
