Exactly snuff. We have had this debate on HC before, and the most generally accepted figures are another forty to fifty years before oil/gas supplies become scarce and several hundred years before coal becomes scarce. There are no figures for nuclear fuel.
That is the global picture of course and does not reflect regional or politically induced shortages.
The major oil companies are busy developing alternative technologies for future use so they will still be in business as the fuel supply gradually changes.
