Future fuels

Fossil fuels deposits worldwide are finite i.e. they will run out one day. How many years more can these fossil fuels last. Scientists estimate that the world has roughly another 40 years of cheap recoverable crude oil left. Natural gas and coal is estimated to last about another 65 years to 230 years respectively.
What will happen when these fossil fuels become exhausted? Where will the world get its energy supplies from?
From where would the most promising alternative sustainable fuel come from?? biomass,solar energy, water or Hydrogen ??????????????????????????

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.
