Primary energy demand is projected to increase by 41% between 2012 and 2035, with growth averaging 1.5% per annum (p.a.). Growth slows, from 2.2% p.a. for 2005-15, to 1.7% p.a. 2015-25 and just 1.1% p.a. in the final decade.

They do not look at other ways to get clean energy (like with nuclear). They just have a plan for trying to get four times more money for $36 trillion of the roughly $120 trillion that will be spent on energy.
