Drag the pointers and you will see that although the initial estimates look good, with only minimal annual growth of say 3-4%/year (compared with China’s economic growth of around 10%) we only have a generation of all three fuels remaining — even assuming that we find ways to overcome the greenhouse gas impacts of each one.

The figures are based on known reserves and do not  include so-called ‘tight’ oil.

The figures appear not to include allowance for the fact that remaining reserves require increasing amounts of energy to extract (so that 100 units of reserves may be only 90 extractable units of energy).
