Himself - President & Co-Founder, The Breakthrough Institute:  We 're basically gon na double the amount of energy we consume by 2050 , we 're gon na triple it or quadruple it by the end of the century .
Himself - President & Co-Founder, The Breakthrough Institute: And meanwhile , if you want to stabilize emissions at some reasonable level , almost all of that energy has to be clean energy .
Himself - President & Co-Founder, The Breakthrough Institute: You 've got to not only create a clean energy infrastructure to replace the fossil - fuel infrastructure we have , but we have to create another _ one _ or maybe two of them between now and 2050 or 2100 in order to reduce our emissions to stabilize the climate .
Himself - President & Co-Founder, The Breakthrough Institute: And that is just nothing that anybody has been talking about or dealing with in the last 20 years .
