Will the 2010s be less carbon intensive than the "noughties"?

I recently introduced my 4th year chemical engineering class to the IPCC AR5 reports.
We were really struck by the reversal in carbon intensity of the global economy in the period 2001-2010.
(Figure SPM.3 of WGIII).
With investments into renewables taking off big time since about 2008, and coal taking a real hammering in the US energy market at the hands of shale gas, can we start to optimistically ask whether the 2020 version of this graph will show a fat orange chunk at the bottom of the bar for the decade 2011-2020?
It is clear that energy intensity reductions won't help to achieve emission reductions.
Low carbon energy options have to contribute big time!
A 54% increase in GHG emissions for the 20 years from 1990 is a dismal defeat for 'team go green Rio 1992'. Will we, the generation that has to win this game, turn it around in the 2nd half? I've got 19 years till retirement...
