Economic growth dipped in 09, but there is widespread complacency that Asia is now back to 'business as usual'. That would require commensurate growth in the availability of energy. (The energy intensity of US GDP has fallen, but it is far from clear that this would have been the case if manufacturing had not been offshored. It seems far from clear that 'green growth' is possible.) A look at the implications of compound growth, and the levelling / decline of some Asian energy sources, highlights the potential constraint of energy availability. China's energy demands are much in the press, and its government is clearly very aware of energy security. Some other countries appear almost oblivious, having received an energy windfall and forgotten its magnitude, and may be surprised to find that they cannot grow as fast without it.
